RFC 1470
FYI on a Network Management Tool Catalog: Tools for Monitoring and Debugging TCP/IP Internets and Interconnected Devices
FYI on a Network Management Tool Catalog ✨
Tools for Monitoring and Debugging TCP/IP Internets and Interconnected Devices 🎀
Okay bestie, here's the deets 💅 This is an FYI from the Network Working Group, labeled RFC 1470, and it was published in June 1993. The editors are R. Enger (ANS) and J. Reynolds (ISI) 👑 It's an informational doc, not a standard. It obsoletes RFC 1147, which is the older version of this same catalog 🦋
Status of this Memo 🌸
This memo gives info to the Internet community. It is not a standard, so nothing here is a spec you have to follow 🫶 Anyone can share it freely, no cap.
Abstract 🧚
The whole point of this FYI is to update FYI 2, which is RFC 1147 [1]. That older doc gave practical info to site admins and network managers. This RFC lists the new and updated tools. 💖
If you have more descriptions to add, send them to noctools-entries@merit.edu ✨ More are always welcome!
Introduction 💜
Okay so, here's the thing: a static doc can't keep up with the latest tools or with fresh updates to the older catalog entries 😭 That's why the NOCtools catalog lives online, on the Internet and on Usenet. Iconic, right? 🌈
news comp.networks.noctools
ftp wuarchive.wustl.edu:/doc/noctoolsPublishing takes time, so some entries in this catalog might be outdated 💀 Please check the online version for the latest info, periodt.
The index in this document matches what's currently in the online docs 📚
The NOCtools2 Working Group of the Internet Engineering Task Force (IETF) put together this revised catalog. Future revisions will go into the online NOCtools catalog. You're encouraged to send in new or revised entries, which get published almost right away ⭐
Caveat Emptor! The IETF does not endorse any of these tools. For the most part, nobody here tested them or checked their descriptions 🙈 Most commercial tool descriptions came straight from the vendors, so read with a grain of salt.
Acknowledgements 🫶
This catalog is the work of the NOCTools2 Working Group, which sits in the User Services Area of the IETF. Huge thanks to Chris Myers, Darren Kinley, Gary Malkin, Mohamed Ellozy, and Mike Patton for their especially notable contributions 👑🔥
Current Postings 🦋
You can grab the current NOCtools catalog through anonymous FTP from wuarchive.wustl.edu. Each entry is its own file, and they all live in the directory /doc/noctools 🍓
Keyword Definitions 🎀
okay bestie, the keywords are always listed in a predefined order 💅 sorted first by the general category they fall into, and then alphabetically ✨ the categories that have been defined for management tool keywords are:
- the general management area a tool relates to, or the tool's functional role;

xnetperfmon from SNMP ResearchTool Descriptions 🎀
Okay so this bit is basically a glow-up catalogue of short tool descriptions for managing TCP/IP internets 🦋 Everything's sorted alphabetically by tool name, and every entry follows the same template, so once you've read one you can read them all 💅
Right after a tool's NAME come its KEYWORDS. These are terse little labels for what a tool is for or what it's like. For the full story you go to the ABSTRACT, which is the detailed purpose and characteristics bit. The MECHANISM section explains how the tool actually works, and CAVEATS is where the warnings live, so please don't skip it 🙈 BUGS covers known bugs or how to report new ones, and LIMITATIONS spells out what the tool can't do. Then there's HARDWARE REQUIRED and SOFTWARE REQUIRED, which describe the environment the tool needs, and finally AVAILABILITY points you to vendors, online repositories, or other places to get it 🧚
Real talk: when tool names clash, the vendor name gets added too 🙈 MITRE and SNMP Research both sent in an updated description of a tool called "NETMON", but these were built independently, they do different things, and they run in different environments. So MITRE's one is listed asNETMON_MITRE, and SNMP Research's is listed asNETMON_WINDOWS_SNMP_RESEARCH. Two NETMONs, zero drama 💖
Here's our first entry, the very first one in the catalogue ✨
Internet Tool Catalog ARPNAME
arp 🌸
KEYWORDS
routing; ethernet, IP;; UNIX, VMS; free. 🍓
ABSTRACT
Okay so arp lets you peek at and even modify the internet-to-ethernet address translation tables that ARP uses, and ARP is the address resolution protocol 🦋 It's giving "look but also touch" 👑
MECHANISM
The arp program goes straight into operating system memory to read the ARP data structures. That's the whole trick, and honestly it's iconic 😭🔥
CAVEATS: None. Nothing to flag here, bestie 💅
BUGS: None known. ✨
LIMITATIONS: Only the super user can modify ARP entries. 🙈
HARDWARE REQUIRED: No restrictions. 🌸
SOFTWARE REQUIRED: BSD UNIX or related OS, or VMS. 🦋
AVAILABILITY AND CONTACT POINT FOR INFORMATION ABOUT THIS TOOL
Available via anonymous FTP from uunet.uu.net, in the directory bsd-sources/src/etc. It comes with 4.xBSD UNIX and related operating systems. For VMS, it's part of the TGV MultiNet IP software package, and also shows up in Wollongong's WIN/TCP and Process Software Corporation's TCPware for VMS. Iconic spread 🌈

Internet Tool Catalog ChameLAN-100
NAME
ChameLAN 100
KEYWORDS
analyzer, benchmark, debugger, generator, map,
reference, status, traffic; bridge, DECnet, ethernet,
FDDI, IP, OSI, NFS, ring; eavesdrop, SNMP, X;
standalone, UNIX.ABSTRACT
Tekelec's ChameLAN 100 is a portable diagnostic system for monitoring and simulating FDDI, Ethernet and Token Ring networks, all at once. Analyzing protocols across multiple topologies, including mixed topologies running at the same time, is a key feature of the product family. Tekelec's proprietary FDDI hardware gives you complete real-time analysis of networks and network components at the full ring bandwidth of 125 Mbps. It connects passively to the network, captures 100 percent of the data, measures performance and isolates real-time problems. Absolutely iconic 🔥
The simulation option gives you full-bandwidth load generation, so you can create and simulate any network condition. You can inject errors and malformed frames. A set of confidence tests makes it easy to evaluate new equipment. The ring map feature displays network topology and the status of all nodes via the SMT process. 🗺️
Monitoring FDDI, Ethernet and Token Ring lets you: view network status in real time; view network, node, or node pair statistics; capture frames; control capture using trigger and filter capabilities; view real-time statistics; view captured frames in decoded format; and view the last frame transmitted by each station. 📊
The following Real-Time Network Statistics for FDDI, Ethernet and Token Ring networks are displayed: frame rate, runts, byte rate, jabbers, CRC/align errors, and collisions. 💀
Product developers can use the ChameLAN 100 to observe and control various events, which helps them debug their FDDI, Ethernet and Token Ring products. End users can do real-time monitoring to test and diagnose problems that come up while developing, installing or managing FDDI, Ethernet and Token Ring networks and network products. They can also use it to help install and maintain Ethernet and Token Ring networks. To isolate specific trouble spots, the ChameLAN 100 uses filtering and triggering techniques for data capture. Higher-level protocol decode covers the TCP/IP, OSI and DECnet protocol suites. Protocol decode of IPX, SNMP, XTP, and AppleTalk is also supported. More protocol decodes are still in development. The ChameLAN 100 family also offers a Protocol Management Development System (PMDS) that lets users develop custom protocol decode suites. 🧚
The FDDI, Ethernet and Token Ring hardware interfaces have independent processing power. Real-time data is monitored unobtrusively at full bandwidth, without affecting network activity. Real-time data can also be saved to a 120MB or optional 200MB hard disk drive for later analysis. FDDI data is captured at 125 megabits per second (Mbps), Ethernet at 10 Mbps, and Token Ring at 4 or 16 Mbps. 🦋
MECHANISM
This portable, standalone unit brings together the power of UNIX, X-Windows and Motif. Its UNIX-based programming interface makes it easy to develop customized monitoring and simulation applications. The ChameLAN 100 can connect to the network at any location using standard equipment. Standard graphical Motif/X-Windows and TCP/IP allow remote control through Ethernet and 10Base T interfaces. Tekelec also offers a rackmounted model, the ChameLAN 100-X. Both models can be controlled remotely from a Sun Workstation. 🌈
CAVEATS
none. 💅
BUGS
none known. ✨
LIMITATIONS
none reported. 🫶
HARDWARE REQUIRED
None. The ChameLAN 100 is a self-contained unit and includes its own interface cards. It installs into a network with standard interface connectors. 🌸
SOFTWARE REQUIRED
None. 🦋

The CMU SNMP Distribution ✨
KEYWORDS
manager, status; IP; NMS, SNMP; UNIX; free, sourcelib.
ABSTRACT
The CMU SNMP Distribution includes source code for an SNMP agent, several SNMP client applications, an ASN.1 library, and supporting documentation.
The agent compiles into about 10 KB of 68000 code. The distribution includes a full agent that runs on a Kinetics FastPath2/3/4 and is built into the KIP appletalk/ethernet gateway. The machine-independent portions of this agent also run on CMU's IBM PC/AT based router. 🖥️
The applications are designed to be genuinely useful in the real world. Information is collected and presented in a useful format, which makes it suitable for everyday status monitoring. Input and output are interpreted symbolically. You can use the tools without referencing the RFCs. Main-character energy 👑

DECADDRS 🌸
NAME: decaddrs, decaroute, decnroute, xnsroutes, bridgetab
KEYWORDS: manager, map, routing; bridge, DECnet; NMS, SNMP; UNIX.
ABSTRACT: These commands display private MIB information from Wellfleet systems, and they're giving real detective energy 🕵️♀️ They retrieve and format values of one or several MIB variables from the Wellfleet Communications private enterprise MIB, using SNMP (RFC1098). They're mainly used to examine the non-IP modules (DECnet, XNS, and Bridging) of a Wellfleet system 💖
decaddrs shows the DECnet configuration of a Wellfleet system acting as a DECnet router, including the static parameters for each DECnet interface. decaroute and decnroute display the DECnet inter-area and intra-area routing tables (that is, area routes and node routes) 🧚 xnsroutes displays the routes known to a Wellfleet system acting as an XNS router. bridgetab displays the bridge forwarding table, with the disposition of traffic arriving from or directed to each station known to the Wellfleet bridge module 🍓
All of these commands take an IP address as the argument and can specify an SNMP community for the retrieval. One SNMP query is performed for each row of the table. Also, the Wellfleet system has to be operating as an IP router for SNMP to be accessible 🫶 Don't skip that part, it matters!
MECHANISM: Management information is exchanged by use of SNMP. 📡
CAVEATS: None. 🎀

EMANATE_SNMP_RESEARCH 👑
NAME: EMANATE: Enhanced MANagement Agent Through Extensions from SNMP Research.
KEYWORDS: alarm, control, manager, reference, security, status; bridge, Ethernet, FDDI, IP, OSI, ring, star; NMS, SNMP; sourcelib.
ABSTRACT: The EMANATE system gives you a run-time extensible SNMP agent that reconfigures an agent's MIB on the fly, without having to recompile, relink, or restart the agent. An EMANATE capable SNMP agent can support zero, one, or many subagents, and it can dynamically reconfigure to connect or disconnect those subagents' MIBs 🧚
The EMANATE system is made of several logically independent components and subsystems:
- Master SNMP agent, which contains an API to communicate with subagents.
- Subagents, which implement various MIBS.
- Subagent Developer's Kit, which contains tools to help implement subagents.
- EMANATE libraries, which provide the API for the subagent.
MECHANISM: A concise API allows a standard means of communication between the master and subagents. System dependent mechanisms are employed for transfer of information between the master and subagents. 🔥
CAVEATS: None. 🎀
BUGS: None known. 🌈
LIMITATIONS: None reported. ✨
HARDWARE REQUIRED: Multiple platforms, including PCs, workstations, hosts, and servers, are supported. Contact SNMP Research for more details. 🖥️

ETHERFIND_SUN 🔎
NAME: etherfind
KEYWORDS: traffic; ethernet, IP, NFS; eavesdrop; UNIX.
ABSTRACT: Etherfind examines the packets that traverse a network interface, and outputs a text file describing the traffic. Each line of text in the file describes a single packet, with values such as protocol type, length, source, and destination 📝 Etherfind can print out all packet traffic on the ethernet, or just the traffic for the local host. You can filter further by protocol: IP, ARP, RARP, ICMP, UDP, ND, or TCP. Filtering can also be done based on source and destination addresses, and on TCP and UDP port numbers 🦋
MECHANISM: In usual operations, and by default, etherfind puts the interface in promiscuous mode. In 4.3BSD UNIX and related OSs, it uses a Network Interface Tap (NIT) to obtain a copy of traffic on an ethernet interface 🧠
CAVEATS: None. 🎀
BUGS: None known. 🌈
LIMITATIONS: Minimal protocol information is printed. It can only be run by the super user. The syntax is painful 😭
HARDWARE REQUIRED: Ethernet. 🖥️
SOFTWARE REQUIRED: SunOS. 💜
AVAILABILITY: Executable included in the Sun OS "Networking Tools and Programs" software installation option 💾
ETHERNET-CODES 🌈
NAME: ethernet-codes
KEYWORDS: reference; ethernet, fddi; ; ; ;
ABSTRACT: Mike Patton of MIT LCS has compiled a very comprehensive list of the IEEE numbers used on Ethernet and FDDI (with some permutation). This file contains collected information on the various codes used on IEEE 802.3 and EtherNet. There are three "pages": type codes, vendor codes, and the uses of multicast (including broadcast) addresses 🍓
MECHANISM: FTP the file and use it like a secret decoder ring. 🗝️✨
CAVEATS ✨
Okay bestie, real talk: this info came from collected wisdom, so there are definitely gonna be omissions 🙈

Internet Tool Catalog: GENERIC-MANAGED-SYSTEM 🎀
NAME
Generic Managed System 💜
KEYWORDS
manager; osi; cmis; unix; free, sourcelib
ABSTRACT
Okay, the Generic Managed System (GMS) is giving foundation energy 🏗️ It implements all the functions that would be common to any OSI managed system. That includes parsing CMIS requests, selecting managed objects according to the scoping and filtering rules, handling notifications and event forwarding discriminators, and more. The whole point is that implementors use the GMS as a base for their own managed object implementations, and a support environment is provided to help with that ✨
MECHANISM
The GMS uses the UCL CMIP library plus a library of C++ objects representing common managed objects and attribute types 🔥
CAVEATS
The system is still experimental 🧪 It's subject to change and isn't yet well documented, so go in with open eyes 👀
BUGS
See above 🙃
LIMITATIONS
None known 🌸
HARDWARE REQUIRED
It has been tested on SUN 3 and SUN 4 architectures 💜
SOFTWARE REQUIRED
The ISODE protocol suite, BSD UNIX, the UCL CMIP Library, and GNU C++ (g++) 🧚
AVAILABILITY
The CMIP library and the related management tools built on it, known as OSIMIS (OSI Management Information Service), are publicly available from University College London in England. You can get them via FTP and FTAM. For more info, email osimis-request@cs.ucl.ac.uk or call +44 71 380 7366 📞
Internet Tool Catalog: GETETHERS 🦋
NAME
getethers 🌷
KEYWORDS
Traffic; Ethernet; Ping; UNIX; Free
ABSTRACT
Getethers is the ultimate ethernet scanner 🔍 It runs through all addresses on an ethernet segment (a.b.c.1 to a.b.c.254) and pings each one, then figures out the ethernet address for each host. The result is a list of hostname/ethernet address pairs for all hosts on the local nework (yes, that's how the original spells it 🙈). The list comes out in plain ASCII, in the file format for the Excelan Lanalyzer, or in the file format for the Network General Sniffer. The plain ASCII version can optionally include the vendor name of each system's ethernet card, which helps you figure out who unknown systems are 🕵️♀️
MECHANISM
Getethers uses a raw IP socket to send ICMP echo requests and receive ICMP echo replies. Then it looks at the kernel ARP table to find the ethernet address of each system that responded 💖
CAVEATS
It assumes the ethernet it's looking at is either a Class C IP network, or part of a Class B IP network that's subnetted with a netmask of 255.255.255.0. This is easy to change, but it's compiled in, so heads up 🎀
BUGS
None known ✨
LIMITATIONS
None 💅
HARDWARE REQUIRED
It has been tested on Sun-3 and Sun-4 (SPARC) systems under SunOS 4.1.x, and on DEC VAXes under 4.3BSD 🖥️
SOFTWARE REQUIRED
It runs under SunOS 4.x and 4.3BSD. It should be easy to port to any other Berkeley-like system 🧚 It needs raw sockets and the ioctl calls to get at the ARP table.
AVAILABILITY AND CONTACT POINT FOR INFORMATION ABOUT THIS TOOL 🌈
It's public domain and freely distributable, which is so generous 🫶 You can get it via anonymous FTP from harbor.ecn.purdue.edu, and it's also been posted to comp.sources.unix. The current version is Version 1.4 from May 1992.

Internet Tool Catalog: GETONE_WELLFLEET 🍓
NAME
getone, getmany, getroute, getarp, getaddr, getif, getid.
KEYWORDS
manager, routing, status; IP; NMS, SNMP; UNIX.
ABSTRACT
These commands retrieve and format values for display, whether that's one or several MIB variables (RFC1066) using SNMP (RFC1098) 📊 getone and getmany grab arbitrary MIB variables. getroute, getarp, getaddr, and getif retrieve and display tabular info like routing tables, the ARP table, and interface configuration. getid shows the system name, identification, and boot time 🧚
Here's the vibe for getone:
getone <target> <mibvariable>It retrieves and displays the value of the MIB variable you designate from the target system you specify. You can also specify the SNMP community name for the retrieval. getmany works the same way but for groups of MIB variables instead of single values. It shows the name, value, and data type of each variable 💅
getroute returns info from the ipRoutingTable MIB structure and displays it in an accessible format. getarp behaves similarly for the address translation table, getaddr does the same for the ipAddressTable, and getif displays info from the interfaces table, supplemented with info from the ipAddressTable 🌸
getid displays the system name, identification, ipForwarding state, and the boot time and date ⏰ All of these take a system name or IP address as an argument, and they can specify an SNMP community for the retrieval. One SNMP query is performed for each row of the table, so it's a whole vibe 🔍

ABSTRACT
Hopcheck lists the gateways traversed by packets sent from the hopcheck-resident PC to a destination 🗺️ It uses the same mechanism as traceroute, but it's for IBM PC compatibles with ethernet connections. Hopcheck is part of a larger TCP/IP package called ka9q, which is for use with packet radio 📻 Ka9q can coexist on a PC with other TCP/IP packages, such as FTP Inc's PC/TCP, but it must be used independently of those other packages. Ka9q was written by Phil Karn, and Hopcheck was added by Katie Stevens, dkstevens@ucdavis.edu 💜 Unlike traceroute, which requires a UNIX kernel mod, hopcheck runs on the standard, unmodified ka9q release 🔥
MECHANISM

Internet Tool Catalog: INTERNET_ROVER 🌈
NAME
Internet Rover ⭐
KEYWORDS
status; IP, SMTP; curses, ping, spoof; UNIX; free, sourcelib.
Okay so the Internet Rover entry is up first, and it's giving prototype network monitor vibes 🦋 It's built out of multiple protocol "modules" that test network functionality, and it has two main pieces: the data collector and the problem display 💖
The data collector runs a series of network tests and keeps a list of problems with the network 🔥 Then you can have tons of display processes all showing that same list, which is honestly so useful in a multi-operator NOC 👑
The display task uses curses, so lots of terminal types can show the problem file, whether it's local or from a remote site ✨ Full source is included 🫶 The data collector is easy to configure and extend, and extra protocol modules and shell script extensions are very welcome 🌸
MECHANISM
Okay the config file is where the magic starts 🧚 It holds a list of nodes, their addresses, a NodeUp? protocol test (ping in most cases), and then a list of further tests to run if the node is actually up 💜 There are modules for TELNET, FTP, and SMTP already 🎀
If the config has a test that isn't recognized, it just assumes a generic test and checks whether a filename exists 🙈 So users can write scripts that create a file when something's wrong, and the data collector only has to check if that file is there to know there's a problem. Iconic, no notes 💅
CAVEATS
None. 🌈
BUGS
None known. ✨
LIMITATIONS
Bestie, this tool can't take action based on test results yet 😭 It's meant for a multi-operator setup and just displays a list of what's wrong with the net 📋
HARDWARE REQUIRED
This software is known to run on Suns and IBM RTs 🍓
SOFTWARE REQUIRED
Curses, 4.xBSD UNIX socket programming libraries, BSD ping 🌸
AVAILABILITY
Full source is available via anonymous FTP from merit.edu (35.1.1.42) in the ~ftp/pub/inetrover directory 🦋 The source and executables are public domain and can be freely distributed for non-commercial use 🎀 It's unsupported, but bug reports and fixes can be sent to wbn@merit.edu 💌
Internet Tool Catalog · IOZONE ✨
NAME
iozone 💖
KEYWORDS
benchmark; nfs;; dos,hp,unix,vmx; free. 🌈
ABSTRACT
Okay so IOZONE is software for checking how well a system does sequential file I/O 🔥 It can be a handy reference for comparing against results from files accessed over NFS, Andrew, and so on 👑
MECHANISM
This test writes an X MEGABYTE sequential file in Y byte chunks, then rewinds it and reads it back 🦋 [The size of the file should be big enough to factor out the effect of any disk cache.] Then IOZONE deletes the temp file 🧹 You can change X and Y with options ✨ The auto test runs IOZONE over and over with record sizes from 512 to 8192 bytes (adjustable) and file sizes from 1 to 16 megabytes (adjustable), and then it makes a table of results 📊 Main character energy ngl 💅
CAVEATS
The file gets written (filling any cache buffers) and then read 😭 If the cache is >= X MB, then most if not all reads come straight from the cache 🙈 But if it's less than or equal to .5X MB, then NONE of the reads will come from the cache 💀 That's because after the write, a .5X MB cache holds the upper .5 MB of the test file, but the reads start from the beginning of the file, which is data that's no longer cached 🫠
For this to be a fair test, the length of the test file has to be AT LEAST 2X the amount of disk cache memory on your system 🍓 If not, you're really just testing how fast your CPU can read blocks out of the cache, which is not a fair test ❌
BUGS
None known at this time. 🌸
LIMITATIONS
IOZONE doesn't normally test the raw I/O speed of your disk or system-em 💅 It tests the speed of sequential I/O to actual files 📁 So the measurement factors in how efficient your machine's file system, operating system, C compiler, and C runtime library are 🧚 What it gives you is the number of bytes per second your system can read or write to a file ✨
HARDWARE REQUIRED
This program has been ported and tested on the following computer operating systems 🌈

NAME
LADDIS 🌸
KEYWORDS
benchmark, generator; NFS; spoof; unix; free. 🌈
ABSTRACT
"LADDIS: A Multi-Vendor and Vendor-Neutral SPEC NFS Benchmark", Bruce Nelson, LADDIS Group & Auspex Systems. 📚
Over the past 24 months, engineers from Legato, Auspex, Data General, DEC, Interphase, and Sun (LADDIS) met regularly to create the LADDIS NFS benchmark 🤝 It's meant to be an unbiased, standard, vendor-independent, scalable NFS performance test 🔥
The whole point of LADDIS is to give users a credible and undisputed test of NFS performance, and to give vendors a publishable standard performance measure that customers can use for load planning, system configuration, and equipment buying decisions 👑 To that end, LADDIS is being adopted by SPEC (the System Performance Evaluation Cooperative, creators of SPECmarks) as the first member of SPEC's System-level File Server (SFS) benchmark suite ✨
"In particular, we have had unexpected interest from some router vendors in using LADDIS to both rate and stress-test IP routers. This is because LADDIS can send back-to-back full-size packet trains, and because it can generate a 90%-Ethernet util on simulated "real" NFS workloads, just like routers encounter in the real world. But LADDIS is for local Ethernet or FDDI nets only, not WAN." 🙈
MECHANISM
Generates NFS requests and measures responsiveness of the server 💖
CAVEATS
"LADDIS is not released yet by SPEC, although a free beta version, quite stable, is available now as PRE-LADDIS. So you might want to put PRE-LADDIS in your listing, noting that full LADDIS availability from SPEC is expected by the end of 1992." ⏳
BUGS
The licensee is requested to direct beta test comments via electronic mail to: "spec-preladdis-comments@riscee.pko.dec.com" 💌
This alias will forward all comments to the SPECSFS mailing list (which includes the LADDIS Group) 📬
LIMITATIONS
LADDIS is for local Ethernet or FDDI nets only, not WAN 🙅♀️
HARDWAE REQUIRED
A host with LAN connectivity. Presumably, a host with enough horsepower to generate an adequate work load 💪
SOFTWARE REQUIRED
LADDIS is a sophisticated Unix-based NFS traffic generator program 🧠

LAN_PATROL 🔍
Internet Tool Catalog
NAME LAN Patrol
KEYWORDS security, traffic; ethernet, star; eavesdrop; DOS.
ABSTRACT LAN Patrol is a full-featured network analyzer that gives you the essential info for effective fault and performance management. 💅 Network managers can easily monitor user activity, find traffic overloads, plan for growth, test cable, uncover intruders, balance network services, and so on. It uses state of the art data collection techniques to monitor all activity on a network, so you get an accurate picture of how it's performing. 📊
LAN Patrol's reports can be saved as ASCII files to disk, and imported into spreadsheet or database programs for further analysis. 🌸
MECHANISM The LAN Patrol interface driver programs a standard interface card to capture all traffic on a network segment. The driver runs from the background of a standard PC, maintaining statistics for each station on the network. You can view the info on the PC's screen, or as a user-defined report output either to file or printer. 🖨️
CAVEATS None. Normal operation is completely passive, which makes LAN Patrol transparent to the network. 🫶

LANPROBE 🛰️
Internet Tool Catalog
NAME LanProbe -- the HP 4990S LanProbe Distributed Analysis System.
KEYWORDS alarm, manager, map, status, traffic; ethernet; eavesdrop, NMS; proprietary.
ABSTRACT The LanProbe distributed monitoring system does remote and local monitoring of ethernet LANs in a protocol and vendor independent manner. 🌐
LanProbe discovers each active node on a segment and displays it on a map with its adapter card vendor name, ethernet address, and IP address. You can add extra info about the nodes, like equipment type and physical location, into the database yourself. 🗺️
When the NodeLocator option is used, data on the actual location of nodes gets entered automatically, and the map becomes an accurate representation of the physical layout of the segment. 🫠 After that, when a new node is installed and becomes active, or when a node is moved or becomes inactive, the change is detected and shown on the map in real time. ⚡ The system also gives the network manager precise cable fault information, displayed on the map. 🔥
Traffic statistics are gathered and displayed, and can be exported in (comma delimited) CSV format for further analysis. Alerts can be set on user defined thresholds. 📈
Trace provides a remote protocol analyzer capability with decodes for common protocols. 🕵️♀️
Significant events (like power failure, cable breaks, new node on network, broadcast IP source address seen, etc.) are tracked in a log that is uploaded to ProbeView periodically. 📝
ProbeView generates reports that can be manipulated by MSDOS based word processors, spreadsheets, and DBMS. 💅
MECHANISM
okay so the setup is one or more LanProbe segment monitors plus ProbeView software, running under Microsoft Windows 🖥️ The LanProbe segment monitor plugs into the end of an ethernet segment and watches all the traffic. You can connect it directly to thin or thick coax, or go through an external transceiver for fiber optic or twisted pair cabling. Segment data gets sent to a workstation running ProbeView over RS-232, ethernet, or a modem connection.
ProbeView runs on a PC/AT class workstation and turns network info into graphical displays. Very pretty, very useful 📊✨
The HP4992A NodeLocator option attaches to the opposite end of the cable from the HP4991A LanProbe segment monitor. It automatically finds where nodes sit on ethernet networks that use coaxial cabling schemes. locating nodes automatically is so iconic 🫶

NAME
LANWatch 🦋
KEYWORDS
alarm, analyzer, traffic; CHAOS, DECnet, DNS, ethernet,
IP, OSI, ring, SMTP, star; eavesdrop; DOS; library,
sourcelib.ABSTRACT
LANWatch 2.0 is an inexpensive, powerful and flexible network analyzer that runs under DOS on personal computers. It needs no hardware modifications to either the host or the network, which is so main character energy 👑 It's an invaluable tool for installing, troubleshooting, and monitoring local area networks, and for developing and debugging new protocols.
Network managers can inspect traffic patterns and packet errors to isolate performance problems and bottlenecks. Protocol developers can use it to inspect and verify proper protocol handling. Since LANWatch is software-only and installs easily on existing PCs, technicians and field service engineers can carry it in their briefcase for network analysis at remote sites. 💼
LANWatch has two operating modes: Display and Examine. In Display Mode, it traces network traffic by showing captured packets in real time. Examine Mode lets you scroll back through stored packets and inspect them in detail. 🔍
To pick a subset of packets for display, storage or retrieval, there's an extensive set of built-in filters. The filters collect only the packets you care about, so you don't have to sort through all the traffic to find specific ones. The built-in filters are alarm, trigger, capture, load, save and search. Each can be controlled separately to match on source or destination address, protocol, or packet contents at the hardware and transport layers. LANWatch also includes enough source code that you can modify the existing filters and parsers or add new ones. 🛠️
The LANWatch distribution includes executables and source for several post-processors: a TCP protocol analyzer, a node-by-node traffic analyzer and a dump file listing tool. 🎀
MECHANISM
It uses many common PC network interfaces by placing them in promiscuous mode and capturing traffic.
CAVEATS
Most PC network interfaces won't capture 100% of the traffic on a fully-loaded network. The ones that miss stuff mostly miss back-to-back packets. 🙈
BUGS
None known. 💖
LIMITATIONS
LANWatch can't analyze what it doesn't see (see Caveats). Fair enough 💀
HARDWARE REQUIRED
LANWatch requires a PC or PS/2 with a supported network interface card.
SOFTWARE REQUIRED
LANWatch runs in DOS. Modifying the supplied source code, or creating additional filters and parsers, requires Microsoft C 5.1.

Internet Tool Catalog LLL_ENTM
NAME
ENTM -- Ethernet Traffic Monitor 💜
KEYWORDS
traffic; ethernet, IP; eavesdrop; VMS; free.ABSTRACT
ENTM is a screen-oriented utility that runs under VAX/VMS. It monitors local ethernet traffic and displays either a real time or cumulative histogram. That histogram shows a percent breakdown of traffic by ethernet protocol type. You can report the info based on packet count or byte count. It also reports the percent of broadcast, multicast and approximate lost packets. The screen display updates every three seconds, and you can also view a real time, sliding history window showing ethernet traffic patterns for the last five minutes. ⏱️
ENTM can also report IP traffic statistics by packet count or byte count. The IP histograms reflect information collected at the TCP and UDP port level, including ICMP type/code combinations. You can sort both the ethernet and IP histograms by ASCII protocol/port name or by percent-value. Every screen display can be saved to a file for printing later. 🖨️
MECHANISM
This utility simply places the ethernet controller in promiscuous mode and monitors the local area network traffic. It preallocates 10 receive buffers and tries to keep 22 reads pending on the ethernet device.
CAVEATS
Putting the ethernet controller in promiscuous mode may severely slow down a VAX system. Depending on how fast the VAX is and how much traffic is on the local ethernet, a large amount of CPU time may get spent on the Interrupt Stack. Running this code on any production system during operational hours is discouraged. ⚠️
Please don't run this on production during operational hours. Seriously. 🙏
BUGS
Due to a bug in the VAX/VMS ethernet/802 device driver, IEEE 802 format packets may not always be detected. A simple test is performed to "guess" which packets are in IEEE 802 format (DSAP equal to SSAP). So some DSAP/SSAP pairs may be reported as an ethernet type, while valid ethernet types may be reported as IEEE 802 packets. 🤷♀️
In some hardware configurations, placing an ethernet controller in promiscuous mode with automatic-restart enabled will hang the controller. The VAX 8650 hangs running this code, while the uVAX IIs and uVAX IIIs do not.

The user is required to have PHY_IO, TMPMBX and NETMBX privileges. When activated, the program first checks that the user process has enough quotas remaining (BYTLM, BIOLM, ASTLM and PAGFLQUO) to run successfully without entering an involuntary wait state. Some quotas need a fairly generous setting. 🧁
The contents of IEEE 802 packets are not examined. Only the presence of IEEE 802 packets on the wire is reported.
The count of lost packets is approximated. If, after each read completes on the ethernet device, the utility detects that it has no reads pending on that device, the lost packet counter goes up by one.
When the total number of bytes processed exceeds 7fffffff hex, all counters are automatically reset to zero.

NAME
map -- Interactive Network Map 🗺️
KEYWORDS
manager, map; CHAOS, ethernet, IP, ring, star; NMS,
ping, SNMP, X; UNIX; free, sourcelib.ABSTRACT
Map draws a map of network connectivity and lets you interactively examine information about various components, including whether hosts can be reached over the network. 🌈
The program comes with complete source and is written in a modular way, so adding different protocol stacks, displays, or hardcopy devices is relatively easy. That's one reason the initial version supports at least two of each. Contributions of additional drivers in any of these areas are very welcome, and so is porting to additional platforms. 🫶
MECHANISM
Net components get pinged using ICMP echo and, optionally, CHAOS status requests and SNMP "gets." The program initializes itself from static data stored in the file system, so it doesn't need to access the network to get running (unless the static files are network mounted).
CAVEATS
As of publication, the tool is in beta release. 🧪

🧚 Internet Tool Catalog: NET_MONITOR
NAME net_monitor 🦋
KEYWORDS: routing, status; DECnet, IP; curses, ping; UNIX, VMS; free, sourcelib. 💖
ABSTRACT 🔥 okay so net_monitor uses ICMP echo (and DECnet reachability info on VAX/VMS) to keep an eye on your network. The monitoring is super simplistic, but it has been genuinely useful, no cap. It periodically checks whether hosts are reachable and shows the results in a full-screen display. It groups hosts into common sets. If every host in a set goes unreachable, it makes a LOT of racket with bells 🔔😭, because it assumes some shared piece of hardware supporting that set has died. The test frequency, the hosts to test, and the groupings are all controlled by one single configuration file 🎀.
The idea came from the PC/IP monitor facility, but net_monitor is an entirely different program with different functionality. Not a copy, bestie 💅.
MECHANISM ✨ Reachability is tested with ICMP echo for TCP/IP hosts, and with DECnet reachability info on VAX/VMS. A DECnet node counts as reachable if it shows up in the list of hosts from a show network command run on a routing node 🦋.
CAVEATS 🌸 This thing is most useful when it runs in a window on a workstation, not on a terminal hooked up to a host. It could be useful ported to a PC (looks easy using FTP Software's programming libraries), but nobody has done it yet. Curses is very slow and CPU hungry on VMS, but it has been run in a window on a VAXstation 2000 💻. Just don't try running it on a terminal connected to an 11/750. Trust me 🙈.
BUGS 🍓 None known.
LIMITATIONS 🧚 This tool is not meant to replace a more comprehensive network management facility, like the one that comes with SNMP.
HARDWARE REQUIRED 💜 A host with a network connection.
SOFTWARE REQUIRED 👑 Curses, the 4.xBSD UNIX socket programming libraries (a limited set), and some flavor of TCP/IP that supports the ICMP echo request (ping). It has run on VAX/VMS with WIN/TCP and on several flavors of 4BSD UNIX, including SunOS 3.2, 4.0, and 4.3BSD. It could be ported to any platform with a BSD-style programming library that has an ICMP echo request facility and curses.

ABSTRACT 🦋 The NetMetrix Load Monitor is a distributed client-server monitoring tool for ethernet, token ring, and FDDI networks. It has a unique "dual" architecture that is compatible with both RMON and X windows 🪟. RMON gives you interoperability and an enterprise-wide view, while X windows enables much more powerful, intelligent applications at remote segments and saves network bandwidth 💅.
The Load Monitor gives you extensive traffic statistics. It looks at load by time interval, source node, destination node, application, protocol, or packet size. The powerful ZOOM feature allows extensive correlational analysis, shown in a wide variety of graphs and tables 📊.
You can answer questions like: Which sources generate most of the load when the network is most heavily loaded, and where is that load going? Which source/destination pairs generate the most traffic over the day? Where should bridges and routers go to optimally partition the network? How much load do applications like the X Windows protocol put on the network, and who generates that load when it peaks? 🤔

ABSTRACT 🌸
the NetMetrix Protocol Analyzer is a distributed client-server monitoring tool for ethernet, token ring, and FDDI networks. its unique "dual" architecture is compatible with both RMON and X windows, and that's the whole vibe 🔥 RMON gives you interoperability, while X windows enables way more powerful, intelligent applications at remote segments and saves network bandwidth.
you can decode and display packets while they're being captured 👀 there are extensive filters to sift through packets before or after trace capture. the capture filter can be set by source, destination between hosts, protocol, packet size, pattern match, or a complete expression using an extensive filter expression language. so many options, I'm obsessed 😭
full 7-layer packet decodes are available for all major protocols, including DECnet, Appletalk, Novell, XNS, SNA, BANYAN, OSI, and TCP/IP. the decodes for the TCP/IP stack cover all the major protocols, including NFS, YP, DNS, SNMP, OSPF, etc. literally ate 🍰
request and reply packets get matched 🦋 packets can be displayed in summary, detail, or hex, with multiple views so you can see packet dialogues side by side.
there's a complete developers' kit for custom decodes, which is giving "build your own era" 🧚
a floating license gives you easy access to the software tool anywhere you need it 💅

NAME ✨
NETMON and iptrace
KEYWORDS 🎀
traffic; IP; eavesdrop; UNIX; free.
ABSTRACT 🌸
NETMON is a facility that sends networking events from the BSD UNIX operating system to a user-level network monitoring or management program. iptrace is a program that plugs into NETMON and logs TCP-IP traffic for performance measurement and gateway monitoring. it's easy to build other NETMON-based tools using iptrace as a model, so you can literally copy the homework 🙈
NETMON lives in the 4.3BSD UNIX kernel. it's independent of hardware-specific code in UNIX, and it's transparent to protocol and network type, with no internal assumptions about the network protocols being recorded. it gets installed in BSD-like kernels by adding a standard function call (probe) to a few points in the input and output routines of the protocols you want to log. 🧚
NETMON is analogous to Sun Microsystems' NIT, but its interface tap function is extended by recording more context information. apart from the timestamp, the installer of the probes chooses what gets recorded. the NETMON probes added to the BSD IP code in the distribution include, as context: input and output queue lengths, identification of the network interface, and event codes labeling packet discards. (the NETMON distribution is geared toward measuring the performance of BSD networking protocols in an IP gateway 💅)
NETMON is designed to sit inside the monitored system with minimal interference to network processing. the estimated and measured overhead is around five percent of packet processing, which is honestly low-key impressive 🔥
the user-level tool "iptrace" comes with NETMON. this program logs IP traffic, either at the IP level only, or as it passes through the network interface drivers as well. as a separate function, iptrace produces a host traffic matrix output. its third type of output is abbreviated sampling, where only a preset number of packets from each new host pair is logged. all three output types can be configured dynamically, in any combination 🦋
OSITRACE, another logging tool with a NETMON interface, is available separately, and it's documented in its own entry in this catalog.
MECHANISM 🧚
access to the information NETMON logs goes through a UNIX special file, /dev/netmon. user reads are blocked until the buffer reaches a configurable level of fullness.
several other NETMON parameters can be tuned at compile time. a diagnostic program, netmonstat, is included in the distribution.

NETscout(tm)
KEYWORDS 🏷️
Alarm, Analyzer, Manager, Status, Traffic;
DECnet, Ethernet, IP, OSI, NFS, Ring, Star, Eavesdrop;
NMS, SNMP;
UNIX;ABSTRACT 👑
The NETscout family of distributed LAN Analyzer devices is intended to give network users a comprehensive capability to identify and isolate fault conditions in data communications networks 🔍. NETscout can collect wide-ranging statistical data, display selectively captured and fully decoded network traffic, set user-defined alarm conditions, and get real-time updates from all segments of a widely dispersed internetwork from a centralized SNMP-compatible network management console 💅.
The NETscout family is based on standards, so operation may be realized in heterogeneous networks, which constitute a multi-protocol, multi-topology, multi-vendor environment 🌈. The fundamental standards it's built on are the Simple Network Management Protocol (SNMP), which defines the protocol for all inter-communications between NETscout devices, and the Remote Monitoring Management Information Base (RMON-MIB), which defines the type of information that is gathered and made available to the user for each network segment 📊.
NETscout clients provide a full array of monitoring and analysis features, including intelligent seven level decoding of all major protocol stacks 🧠:
DOD including TCP/IP XNS Novell
DECNET including LAT ISO APPLETALK
IBM Token Ring Vines NETBIOS/SMB
SNMP including RMON-MIB SUN-NFS SMTNETscout agents support all nine groups of the RMON-MIB standard 💖. They can work with any SNMP-based network management system and currently support Ethernet and Token Ring 🫶.
MECHANISM ⚙️
NETscout is split into two distinct subcategories. The first is the "Client," which is the user console where operational commands are issued and where all results and diagnostic information are displayed 🖥️. In a NETscout topology, it's feasible to have multiple clients active at the same time within a single network 👯♀️. The second category is the "Agent," a hardware/software device attached to a specific network segment. It gathers statistical information for that segment and provides a window into that segment, where network traffic may be observed and gathered for more detailed user analysis 🔭. A typical network will have multiple segments and multiple agents, up to the point of having one agent for each logical network segment 🧚.
NETscout Model 9210 is a software package which, when combined in a Sun SPARCstation with SunNet Manager running under Open Windows, implements the NETscout client function ☕. SunNet Manager provides the background operational tools for client operation, while the NETscout software provides application-specific functions related to RMON-MIB support, as well as all software necessary to perform the protocol decode function. SunNet Manager also implements a network map file, which includes a topographical display of the entire network and is the mechanism for selecting network elements to perform operations 🗺️.
NETscout Model 9215 is a software package that operates in conjunction with SunNet Manager and implements the statistics monitoring function only 📉. That is, it does not include the protocol decode function or the mechanism to retrieve actual data from a remote agent. It does, however, include complete statistics gathering and event and alarm generation 🚦.
Frontier NETscout Models 9510 and 9515, and Model 9610 and 9615, are agent software packages that implement selected network diagnostic functions when loaded into a Sun SPARCstation (9510, 9515) or a SynOptics LattisNet Hub (9610, 9615), respectively, which is connected to an Ethernet network segment using conventional network interface hardware 🔌. Models 9510 and 9610 support all nine RMON-MIB groups, including "filters" and "packet capture," and thus provide for complete protocol monitoring and decode when used with a client equipped with protocol decode software 🏆. Models 9515 and 9615 include support for seven RMON-MIB groups, which excludes "filters" and "data capture," and therefore perform network monitoring only through collection and presentation of network statistics, events, and alarms 📡. All models also support the MIB2 system and interface groups 🌸.
Frontier NETscout Models 9520 and 9525, and Model 9620 and 9625, are agent software packages that are identical in function to their respective models described above, except that they are for use on Token Ring segments 💍.
CAVEATS ⚠️
The RMON-MIB standard for Token Ring applications has not yet been formally released and is not approved. NETscout products correspond to the latest draft for Token Ring functions and will be updated as required to conform to the standard as it is approved.

Okay bestie, so we're picking up with Netstat 💅 and then we're going full tour of the Internet Tool Catalog 🦋
ABSTRACT
Netstat is a program that digs into the network data structures living inside the kernel, then shows you the results as plain ASCII text in your terminal 💻✨ It can give you reports on the routing table, TCP connections, TCP and UDP "listens", and protocol memory management. So many receipts 🧾🌸
MECHANISM
Netstat reads operating system memory to pull out the kernel routing tables. Lowkey the whole trick 🧚
CAVEATS
Kernel data structures can change while netstat is running, so the snapshot you see might shift on you mid-read 🙈
BUGS
None known. Iconic ✨
LIMITATIONS

HARDWARE REQUIRED
No restrictions. Literally runs on whatever 🫶
SOFTWARE REQUIRED
BSD UNIX or a related OS, or VMS 🦋
AVAILABILITY
You can grab it by anonymous FTP from uunet.uu.net, in the directory bsd-sources/src/ucb. It's available with 4.xBSD UNIX and related operating systems. For VMS, it comes as part of the TGV MultiNet IP software package, and also in Wollongong's WIN/TCP 🌈
Network Integrator I 🧚
KEYWORDS
map, traffic; ethernet; UNIX.
ABSTRACT
This tool monitors traffic on network segments 🔥 Everything gets dumped either into a log file or, if you want to watch live, into a command tool window. Every bit of data is time-stamped by date and time, and logging can keep going for up to 24 hours. Main character energy for real 👑
The tool is super flexible about how it collects and presents data. You can specify traffic filters by header values of numerous protocols, including the ones used by Apple, DEC, Sun, HP, and Apollo. It can monitor bandwidth utilization, plus actual load and peak throughput. It can also analyze a network's topology and record where all the operational nodes on a network are located 🗺️💖
Data can be displayed in six separate formats of bar graphs 📊 There are also several routines for making statistical summaries of the data it collected.
MECHANISM
The tools work through RPC and XDR calls 🎀
CAVEATS
Although the tool adds only a little traffic to a network, generating statistics from captured files takes a significant portion of a workstation's CPU. Heads up, bestie 💀
BUGS
None known. ✨
LIMITATIONS
You must be root to run the monitor 🔐 There doesn't seem to be a limit to the number of nodes, since it monitors by segments. The only major limitation is how much disk space a user can commit to the log files. You can control the size of the log files through the tool's parameters, which is so helpful 🫶

NFSwatch 🦋
NAME
nfswatch
KEYWORDS
Traffic; Ethernet, IP, NFS; Curses, Eavesdrop; UNIX; Free
ABSTRACT
Nfswatch monitors all incoming ethernet traffic to an NFS file server and sorts it into several categories 🍓 The number and percentage of packets received in each category shows up on screen in a continuously updated display. So satisfying to watch 🌈
By default, nfswatch monitors all packets destined for the local host over a single network interface. You can pick a specific interface to monitor, or all interfaces at once. NFS traffic to the local host, to a remote host, from a specific host, between two hosts, or all NFS traffic on the network can be monitored. Choices, choices 💜
Categories of packets monitored and counted include:
ND Read,ND Write,NFS Read,NFS Write,NFS MountYellow Pages (NIS),RPC Authorization,Other RPCTCP,UDP,ICMP,RIP,ARP,RARPEthernet Broadcast, andOther
Packets are also tallied by file system or by file (specific files can be watched as an option), by NFS procedure name (RPC call), or by NFS client hostname 🧚
There are facilities for taking "snapshots" of the screen, and for saving data to a log file for later analysis. The analysis tool is included too 📸
MECHANISM
Nfswatch uses the Network Interface Tap, nit(4) under SunOS 4.x, and the Packet Filter, packetfilter(4), under Ultrix 4.x, to put the ethernet interface into promiscuous mode. It filters out NFS packets and decodes the file handles to work out how to count each packet. Big brain moves 🧠✨
CAVEATS
The NFS file handle is a non-standard (server private) piece of data, so nfswatch must be modified to understand the file handles used by various implementations. Right now it knows about the SunOS 4.x and Ultrix file handle formats 🙈
BUGS
It does not monitor FDDI interfaces. (It should be a simple change, but neither author has access to a system with FDDI interfaces for testing 😭)
LIMITATIONS
Up to 256 exported file systems and 256 individual files can be monitored at any time 🍓
Only NFS requests are counted. The NFS traffic that a server generates in response to those packets is not counted 💀
HARDWARE REQUIRED
Any Ultrix system (VAX or DEC RISC hardware) 🖥️
SOFTWARE REQUIRED
Ultrix release 4.0 or later. For Ultrix 4.1, it may require the patched if_ln.o kernel module, which you can get from Digital's Customer Support Center 🎀

NNStat 💜
NAME
NNStat
KEYWORDS
manager, status, traffic; ethernet, IP; eavesdrop, NMS; UNIX; free.
ABSTRACT
NNStat is a collection of programs that gives you internet statistic collecting capability 📊 Its strategy is to collect traffic statistics via a promiscuous ethernet tap on the local networks, rather than instrumenting the gateways. If all traffic entering or leaving a network (or a set of networks) goes across a local ethernet, then stationing a statistic gathering agent on each local network lets you build a profile of network traffic. A global manager retrieves the statistical data from the local agents 🌐
A program called "statspy" does the data gathering. Basically, statspy reads all packets on an ethernet interface and records all the information of interest. It works out what's of interest by examining each packet and checking whether the source or destination IP address is one being monitored (typically a gateway address). If it is, the contents of the packet are examined to see if they match further criteria 🔍
A program called "collect" does the global data collection. It periodically polls the various statspy processes in the domain of interest to retrieve locally logged statistical data 🧚
The NNSTAT distribution comes with several sample awk programs that process the logged output of the collect program 🎀
MECHANISM 🦋
Okay so the local agents (statspy processes) quietly collect raw traffic data through a promiscuous ethernet tap 👀. Then a global manager (the "collect" process) swoops in and grabs the statistical, filtered, or otherwise reduced data from those local agents 💅.
CAVEATS ✨
None. 🫶
BUGS 🐛
Bug fixes, extensions, and other pointers get discussed in the electronic mail forum called bytecounters 📬. To join, send a request to bytecounters-request@venera.isi.edu.

LIMITATIONS 🚧
NNStat presumes a topology of one or more long haul networks gatewayed to local ethernets 🌐.
A kernel mod is required to run with SunOS4. These mods are described in the bytecounters archive 🧚.
HARDWARE REQUIRED 💻
You need an ethernet interface, plus a Sun 3, Sun 4 (SPARC), or PC RT workstation 🍓.
SOFTWARE REQUIRED 🎀
The distribution is for BSD UNIX, but it could easily be adapted to any UNIX with promiscuous ethernet support 💜.

NOCOL(8) 🌈
NAME 💖
nocol - network monitoring tools for an IP network
SYNOPSIS 🔍
This is an overview of the NOCOL software.
DESCRIPTION 📝
NOCOL (Network Operations Center On-Line) is a collection of network monitoring programs that run on Unix systems 🖥️. The software is made up of a bunch of monitoring agents that poll various parameters from any system and put them in a format suitable for post-processing. The post-processors can be a display agent, an automated troubleshooting program, an event logging program, and so on ✨.
Right now there are monitors for reachability, SNMP traps, data throughput rate, and nameservers, and they're all in use 🙌. Adding more monitoring agents is easy, and they'll get added as necessary. A display agent, nocol(1), using curses has already been built. Work on an "intelligent" module is in progress for event logging and some automatic troubleshooting 🤖.
All data collected by the monitoring agents follows a fixed (non-readable) format. Each data entry is called an event in NOCOL, and each event has certain flags and a severity attached to it 🚩. The display agent, nocol(1), shows the output of these monitoring agents depending on the severity of the event. You can have multiple displays running simultaneously, and they all process the same set of monitored data 👯.
There are four severity levels for an event: CRITICAL, ERROR, WARNING and INFO 🚨. Each monitoring agent controls the severity level independently, and whether it raises or sets an event's severity to any level depends on the logic built into that monitoring agent 🧠.
For example, if a site is unreachable via ping, pingmon(8) gives it a severity of WARNING. If the site is still unreachable after some time, that severity gets elevated to CRITICAL 📈. With trapmon(8), an SNMP trap message of "EGP neighbor lost" is directly assigned a severity of CRITICAL, while a "Warm Start" trap is assigned a severity of WARNING 😬.
The display agent (and any other data post-processors) uses this event severity to decide whether to display the event, troubleshoot it, or log it, depending on the display severity level the user selected 🎯.
The software is super flexible and makes enhancements and development take a minimum amount of effort 💅. The display module processes all the files in the data directory and displays them one after another. This means new monitoring programs can just start generating data in the data directory, and the display module will automatically start showing the new data 🪄. The monitoring tools can be changed, and the only thing that has to stay common across all the modules is the EVENT data structure 🫶.
CURRENT MODULES 🧩
NOCOL currently consists of the following modules:
nocol
This one simply displays the data collected by the monitoring agents. It uses the curses screen management system to support a wide variety of terminal types 🖼️. An event gets displayed when:
- The severity level of the event is higher than the severity level set in the display.
- The display filter (if set) matches some string in the event line.
The display can run in the regular 80 column mode or the extended 132 column mode. Critical events show up in reverse video (if the terminal type supports it) ⚡. There are also extras like showing informational messages in part of the window, automatic window resizing, and operator acknowledgement via a bell when a new event goes critical 🔔.
ippingmon
This one monitors the reachability of a site via "ICMP" ping packets (ICMP was preferred over SNMP for many obvious reasons 🙄). It can use the default output from the system's ping program, but an accompanying program, multiping, can ping multiple IP sites at the same time. That makes it the better pick for monitoring a big list of sites 🏃♀️. A site is marked unreachable if a certain number of packets is lost, and its severity level goes up each time it tests unreachable 📉.
osipingmon
This one is similar to the ippingmon module, but it uses the OSI ping program instead. There's no multiple ping program for OSI sites yet 🥲. The only requirement is that the system's ping program output matches the typical BSD IP ping program's output.
nsmon
This one monitors the nameservers (named) on a list of specified hosts. It periodically sends an SOA query for the default domain. If the queried nameservers can't resolve the query, the site gets bumped up to CRITICAL status 🚑.
tpmon
This one monitors the throughput (kbits per second) to a list of hosts 📶. The program connects to the discard socket on the remote machine (using a STREAM socket) and sends large packets for a small amount of time to evaluate the effective throughput. If the throughput drops below a certain threshold (set in the configuration file), it elevates a site to WARNING level ⚠️.
trapmon
This one converts all SNMP traps into a format that NOCOL can display. The severity of the various traps is preset, and it can be changed at compilation time 🛠️.
PLATFORM 🖥️
Any Unix system with the curses screen management library and IP (Internet Protocol) programming facility works 💖. It has been tested on Sun Sparc 4.1.1, Ultrix, and NeXT systems. Porting to other platforms might need minor adjustments depending on the vagaries of the different vendors (mostly in the include files) 🙃.
AVAILABILITY 🌍
NOCOL was developed at JvNCnet and has been used to monitor the JvNCnet wide area network since 1989 🎉. It's available via anonymous FTP from ftp.jvnc.net under pub/jvncnet-packages/nocol.tar.Z. The system running at JvNCet can be viewed by logging into the host nocol.jvnc.net with username nocol. Use rlogin instead of telnet, since it handles X window terminal types way better 🪟.
To be added to the NOCOL mailing list (for future updates and bug fixes), send a message to nocol-users-request@jvnc.net with your email address 💌.
FUTURE DEVELOPMENTS 🔮
Possible future enhancements are:
- Event logging.
- Adding an automated troubleshooting mechanism for when a site's severity level reaches a particular level 🤖.
- SNMP monitors to watch the state of certain variables (interface errors, packet rate, route state changes) 👀.

NPRV 🦋
NAME 💫
NPRV -- IP Node/Protocol Reachability Verifier
KEYWORDS 🏷️
map, routing, status; IP; ping; VMS; free.
ABSTRACT 💜
NPRV is a full-screen, keypad-oriented utility that runs under VAX/VMS 🖥️. It lets you quickly scan through a user-defined list of IP addresses (or domain names) and verify a node's reachability 🔍. Reachability is determined by performing an ICMP echo, a UDP echo, and a TCP echo at alternating three second intervals ⏱️. The total number of packets sent and received gets displayed, along with the minimum, average, and maximum round-trip times (in milliseconds) for each type of echo 📊.
There's also a "trace route" function that works out the path from the local system to the remote host 🛤️. Once all of the trace route information has filled the screen, you can write a "snapshot" of the screen to a text file 📸. When you exit the utility, those text files can be used to generate a logical network map showing how hosts and gateways are interconnected 🗺️✨.
Okay bestie, here's how the ICMP echo works 🦋 It's done by sending ICMP ECHO REQUEST packets 💖. The UDP and TCP echoes work by connecting to the UDP/TCP echo ports (port number 7) 🎀. Trace route info gets pieced together by sending alternating ICMP ECHO REQUEST packets and UDP packets with very large destination UDP port numbers (in two passes) 🧚. Each packet starts with a TTL (time to live) of 1, so this should make the first routing gateway send back an ICMP TIME EXCEEDED error 🌸. Then every packet goes out with a TTL of 2, so the second routing gateway should send back that same error, then 3, and so on 💅. This keeps going until an ICMP ECHO REPLY or UDP PORT UNREACHABLE comes back 👑. That means the remote host was reached and the trace route info is complete ✨.
CAVEATS
This utility sends one echo packet per second (ICMP, UDP or TCP), plus one trace route packet per second 🫶. If a trace route packet comes back in less than one second, another one gets sent in 100 milliseconds 😭. This could cause a significant amount of contention on the local network 💀.

The user is required to have SYSPRV privilege to perform the ICMP Echo and trace route functions 🔒. The utility will still run with this privilege disabled, but only the UDP Echo and TCP Echo info will show up 🙈. It's written in C, but unfortunately it can't be easily ported over to UNIX, since it uses a lot of VMS system calls and all screen I/O is done with the VMS Screen Management Routines 😩.

Okay, SNMP proxy agents are literally the MVP 👑 They let you monitor and control network elements that you otherwise couldn't reach with SNMP, like a network bridge that speaks some proprietary management protocol 🙈 They can also shield real SNMP agents from a bunch of redundant management agents by using caches. And they're great for building fancy MIB access policies. Iconic.
Here's what the proxy agent daemon does, step by step:
- listens for SNMP queries and commands from logically remote network management stations,
- translates and retransmits those as appropriate network management queries or cache lookups,
- listens for and parses the responses,
- translates the responses into SNMP responses, and
- returns those responses as SNMP messages to the network management station that originated the transaction.
It also sends SNMP traps out to whoever's listed as a trap receiver 🔔 Adding more vendor-specific variables is supposed to be really easy, which is so thoughtful of them 🌸 And the whole thing ships with source code, a strong set of portable libraries for building and parsing SNMP messages, and a bunch of command line utilities. 💅

KEYWORDS
analyzer, generator, traffic;
DECnet, ethernet, IP, NFS, OSI, ring, SMTP, star;

standalone.ABSTRACT
The Network General Sniffer is a protocol analyzer for LAN diagnostics, monitoring, traffic generation, and troubleshooting. It's basically a whole toolkit 🧰 It can capture every packet on a network and decode all seven layers of the OSI protocol model, which is seriously impressive 😭🔥
Capture frame selection works through several different filters:
- protocol content at lower levels,
- node addresses,
- pattern matching (up to 8 logically-related patterns of 32 bytes each), and
- destination class.
And if the built-in protocol interpretation isn't enough, you can write your own customized protocol interpreters and link them to the Sniffer software. Main character energy 👑🦋
Okay so the Sniffer is giving main character energy 🦋 It shows you network traffic and performance stats in real time, in whatever format you pick, and it translates numeric station addresses into symbolic names or manufacturer ID names 💅 It tracks frames accepted, Kbytes accepted, and buffer use, and every network version adds its own extra counters for its own stuff. Activity can be shown as frames/second, Kbytes/second, or per cent of network bandwidth utilization 📊
Data collection can go to a printer or get saved to disk as a print-file or a spread-sheet 🌸
The protocol suites it understands are giving full buffet 🍓 Banyan Vines, IBM Token-Ring, Novell Netware, XNS/MS-Net (3Com 3+), DECnet, TCP/IP (including SNMP and applications-layer protocols like FTP, SMTP, and TELNET), X Windows (for X version 11), NFS, and a bunch of SUN proprietary protocols (including mount, pmap, RPC, and YP) 🫶 The LANs it supports are ethernet, Token-ring (4Mb and 16Mb versions), ARCNET, StarLAN, IBM PC Network (Broadband), and Apple Localtalk Network 🌈
Internet Tool Catalog: Sniffer
MECHANISM
Okay the Sniffer is a self-contained, portable protocol analyzer, so all it needs is AC line power and a connection to a network and it's ready to go 🧚 It's normally passive (unless it's in Traffic Generator mode), and it captures images of all or just selected frames into a working buffer so you can analyze and display them right away ✨
It's a standalone device, and it comes in two platforms: one for single network topologies and one for multi-network topologies 💜 Both include Sniffer core software, a modified network interface card (or multiple cards), and optional protocol interpreter suites 🎀
All Sniffer functions can be controlled remotely from a modem-connected PC, and its output can be imported into database or spreadsheet packages 💖
CAVEATS
In normal use the Sniffer is passive, so it won't adversely effect network performance 🙈 Performance degradation will show up, obvi, if the Sniffer is set to Traffic Generator mode and connected to an active network 💀

Okay, the SpiderMonitor and SpiderAnalyzer are protocol analyzers for ethernet LAN diagnostics, monitoring, traffic generation, and troubleshooting. 🔍 The SpiderMonitor can capture every single packet on a network and decode the first four layers of the OSI protocol model, which is lowkey amazing. The SpiderAnalyzer gets extra software that lets it decode the higher protocol layers. 💖
It understands these protocol suites: TCP/IP (including SNMP and applications-layer protocols), OSI, XNS, DECnet and IPX. 🧩 You can write your own decodes in 'C' with the Microsoft version 5.0 'C' compiler, and a decode guide comes with it so you're not left guessing. 📖
The SpiderAnalyzer supports multiple filters at the same time for capturing packets using predefined patterns and error states. 🎯 Filter patterns can also trigger on NOT matching 1 or more filters, an alarm, or a specified time. ⏰
The SpiderAnalyzer can also use TDR (Time Domain Reflectometry) to find media faults, open or short circuits, or transceiver faults. ⚡ It can transmit OSI, XNS, and Xerox link-level echo packets to user-specified stations, and it performs loop round tests. 🔁
In traffic generation mode, the SpiderAnalyzer can generate packets at random intervals of random lengths, or any combination of random or fixed interval or length. 🎲 It can also make packets with CRC errors, packets that are too short, or packets that are too long. Chaotic, but in a useful way 😭
Output from the SpiderMonitor/Analyzer can be imported to database or spreadsheet packages. 📊

NAME
SPIMS -- the Swedish Institute of Computer Science
(SICS) Protocol Implementation Measurement
System tool.KEYWORDS
benchmark, debugger; IP, OSI; spoof; UNIX. 🧪
ABSTRACT
SPIMS is used to measure the performance of protocol and "protocol-like" services, including response time (two-way delay), throughput, and the time to open and close connections. ⏱️ It's been used to:
- benchmark alternative protocol implementations, 🏁
- observe how performance varies when parameters in specific implementations have been varied (i.e., to tune parameters). 🎛️
SPIMS currently has interfaces to the DoD Internet Protocols: UDP, TCP, FTP, SunRPC, and the OSI protocols from the ISODE 4.0 distribution package: FTAM, ROSE, ISO TP0, and to Sunlink 5.2 ISO TP4, as well as Stanford's VMTP. 🌐 There's also a rudimentary set of benchmarks, stubs for new protocol interfaces, and a user manual. 📘
For an example of the use of SPIMS to tune protocols, see:
Nordmark & Cheriton, "Experiences from VMTP: How
to achieve low response time," IFIP WG6.1/6.4:
Protocols for High-Speed Networks, May 1989,
Zurich. To be published.For an example of how SPIMS can be used to benchmark protocols, see:

Stromqvist "Application Protocols and Performance
Benchmarks", IEEE Communications Magazine, June

Protocol Benchmarks', IFIP WG6.1/6.4 Protocols
for High-Speed Networks, May 1989, Zurich, pp
57-67MECHANISM
SPIMS runs as user processes and uses a TCP connection for measurement set-up. 🧵 Measurements take place between processes over the measured protocol. SPIMS generates messages and transfers them via the measured protocol service according to a user-supplied specification. It has a unique measurement specification language used to describe a measurement session. That language has constructs for different application types (e.g., bulk data transfer), for specifying frequency and sequence of messages, for distribution over message sizes, and for combining basic specifications. 🧠 These specifications are independent of both protocols and protocol implementations, so they can be used for benchmarking.

NAME spray
KEYWORDS benchmark, generator; IP; ping; UNIX.
ABSTRACT Spray is a traffic generator 💥 It blasts out RPC or UDP packets, or ICMP Echo Requests, at a remote procedure call application on the destination host. After a set number of packets have gone out, it asks that remote application how many made it through. On a LAN, the gap between packets sent and packets received is the stuff the destination host had to drop because its queue got too long. So you can get a throughput measure relative to system speed and network load 📈
MECHANISM See above.
CAVEATS Spray can congest a network. 🚨
BUGS None known.
LIMITATIONS None reported.
HARDWARE REQUIRED No restrictions.
SOFTWARE REQUIRED SunOS
AVAILABILITY Supplied with SunOS.

ABSTRACT Tcpdump can interpret and print headers for ethernet, IP, ICMP, TCP, UDP, NFS, ND, ARP/RARP, and AppleTalk 🍓 It has proven super useful for examining and evaluating the retransmission and window management operations of TCP implementations, so if you're into TCP drama, this is your tool 🎀
MECHANISM Much like etherfind, tcpdump writes a log file of the frames traversing an ethernet interface. Each output line includes the time a packet is received, the type of packet, and various values from its header 🕰️
CAVEATS None.
BUGS None known.
LIMITATIONS The public domain version requires a kernel patch for SunOS. TCPware for VMS currently interprets headers for IP, TCP, UDP, and ICMP only 🙈
HARDWARE REQUIRED Any Ultrix system (VAX or DEC RISC hardware)
SOFTWARE REQUIRED Ultrix release 4.0 or later. For Ultrix 4.1, you may need the patched "if_ln.o" kernel module, which is available from Digital's Customer Support Center 🛠️

Internet Tool Catalog · TCPLOGGER 🧚
NAME tcplogger
KEYWORDS traffic; IP; eavesdrop; UNIX; free.
ABSTRACT Tcplogger is a set of modifications to the 4.3BSD UNIX source code, plus a big library of post-processing software 📚 It records timestamped info from TCP and IP packets sent and received on a specified connection. For each TCP packet, it records things like sequence number, acknowledgement sequence number, packet size, and header flags. For an IP packet, it records header length, packet length, and TTL values. Customized use of the TCP option field lets you detect lost or duplicate packets 👀
MECHANISM The routines of 4.3BSD UNIX in the netinet directory were modified to append information to a log in memory. A user process reads the log continuously and writes it to a file. A TCP option was added to start logging a connection. A lot of post-processing software has been written to analyze the data 🧠
CAVEATS None.
BUGS None known.
LIMITATIONS To get a log at both ends of the connection, the modified kernel should be running on both hosts 🫣
All connections are logged in a single file, but there's software included to filter out the record of a single connection.
HARDWARE REQUIRED No restrictions.
SOFTWARE REQUIRED 4.3BSD UNIX (as modified for this tool).

Westborough, MA 01581 Telex: 928124Internet Tool Catalog · TRACEROUTE 🗺️
NAME traceroute
KEYWORDS routing; IP; ping; UNIX, VMS; free.
ABSTRACT 🦋
Okay bestie, so traceroute is the tool that figures out the path your packets take from source to destination 🗺️✨ It's the backup plan for when the IP record route option just can't cut it. That happens when intermediate gateways quietly discard packets, when the route is too long for the datagram's capacity, or when some middle IP implementation doesn't support record route at all 💀 It also reports round trip delays between the source and each intermediate gateway, so you can tell which gateway is adding how much to the end-to-end delay. Iconic 😭
Enhanced versions of traceroute let you specify loose source routes for datagrams 🧚 That means you can investigate the return path from remote machines back to your local host. The way that's giving detective energy 🔍💖
MECHANISM 🌸
Traceroute depends on the ICMP TIME_EXCEEDED error reporting mechanism 🎀 When a gateway gets an IP packet whose time-to-live value is 0, it sends an ICMP packet back to the host that generated the packet. So you send packets toward a destination with a TTL of 0, and the next hop shows up as the source of the ICMP TIME EXCEEDED message. Then you increment the TTL field, and the later hops reveal themselves one by one 🪜
Each packet gets time stamped as it goes out ⏱️ That time stamp comes back inside the ICMP packet, so the round trip delay can be calculated. Math and tea 🍵
CAVEATS 💅
Some IP implementations forward packets with a TTL of 0, so those hops escape identification 🙈 Others use the TTL field from the arriving packet as the TTL for the ICMP error reply, which slows down identification. Annoying, not gonna lie 😤
Sending datagrams with the source route option can make some gateways crash 💀 It is considered poor form to repeat this behavior. Be a good girl and don't do it 🫶
BUGS 🐞
None known. Honestly iconic 👑
LIMITATIONS 🌧️
Most versions of UNIX have errors in the raw IP code, so the standard version of traceroute needs kernel mods to work 😩 There's a version that runs without kernel mods under SunOS 3.5 (see below), but it only operates over an ethernet interface. Lowkey a bummer, but it's a start 🥲
HARDWARE REQUIRED 🍓
No restrictions. Literally any hardware 💖
SOFTWARE REQUIRED 💜

ABSTRACT ✨
The Paramax Network Security Server (NSS) is a security officer's tool for centralized security management of TCP/IP-based networks 🛡️ It collects, stores online, maintains, and correlates audit data from hosts, workstations, servers, and network devices. Smart, organised, iconic 👑
Through the X window based user interface, a security officer can review and analyze this audit data at the NSS 👀 They can also select and request filtered portions of host audit data, and receive and analyze security alerts from across the network 🚨
The NSS supports centralized access control of network resources through its ability to create and update user and host access permissions data 🔑 The user access permissions data identifies the network addresses each user is permitted to access. The host access permissions data identifies the network addresses between which communication is permitted. Basically a bouncer with a clipboard 💅
The NSS also supports centralized management of user authentication data (user IDs and passwords) and other user data for use by hosts, workstations, and servers in the network 🫶 It generates pseudo-random pronounceable passwords for the security officer to select and assign to users. Pronounceable passwords?? Iconic, actually 🤭
The NSS deadman timer locks the NSS screen or logs the security officer off the NSS after periods of inactivity 😴 A biometric authentication device is optional for rigorous fingerprint authentication of users at the NSS, and logins to the NSS itself are permitted only at the console 🔏 Right now the NSS provides centralized security management for a System High Network, and it's being upgraded for a Compartmented Mode environment 🌈 Glow up era ✨
MECHANISM 🌸
The NSS uses the Audit Information Transfer Protocol (AITP) for transferring security alerts and audit data 📡 AITP is NOT proprietary, and the specification is available from the address listed below 📄 Access to the NSS audit database is provided via the Structured Query Language (SQL) 🗄️

KEYWORDS 💜
manager; ; snmp, x; sun, dec, dos;.
Okay bestie, we're picking up mid-entry with the Management Station, and it is giving main character energy 💅✨
Management Station is a network management software product that supports SNMP 🖥️. Release 3.0 brings in a distributed network management architecture, which is a glow-up because it helps fix the scalability and reliability problems you get when one cpu tries to handle every single SNMP management task 😭. There are also a bunch of applications, and every one of them is user-configurable 🎀. Here's the lineup:
General Info
X Windows, 11.4 based, implemented with the OSF/Motif 1.1.1 toolkit. Every configuration file gets an X Windows interface 🦋. Most applications have a "verbose" mode so you can watch the SNMP PDU traffic go by 👀. You get on-line help and Reference manual pages, and it's ANSI C compliant 💜.
Network Management Daemon
This daemon handles device discovery, trap/alarm management, and fault monitoring for the network map 🗺️. It talks to other distributed daemons and any connected stations over SNMP/TCP. It's configured through the Manager MIB, and it also includes the SMUX MIB (RFC 1227) 🧚. It can send info to INGRES, Oracle, or Sybase through an ESQL interface 🍓.
The user-defined actions are:
- send alarm to map
- send info to flat file
- execute ESQL command
- call any UNIX system command
- forward traps and filter user-defined alarms
User-defined alarms can use any boolean expression, and MIB variable expressions can be combined with AND/OR statements 🔥.
MIB Compiler
It's an ASN.1 MIB compiler with an X Windows interface 🌸. It accepts RFC 1155 and 1212 format, and most vendor-specific MIBs plus proposed Internet standard MIBs are already included 🎀.
Network Map
This is a comprehensive network monitoring map with a click and drag interface, plus hierarchical and virtual views 🦋. It comes with toolkit and preferences applications, along with device discovery 🔍. Device resolution uses the /etc/hosts file, NIS, or DNS 🌈. You also get background pixmapping, a user-definable menu bar, and network manager and console operator modes controlled by UNIX group permissions 👑. You can run multiple maps without any limitation ✨.
MIB Form and MIB Form Editor
These are User-designed, X-based SNMP applications 💅. They give MIB variables an alias and interpret the returned values, and they support GET NEXT and SET 💖. You get user-defined polling and multi-device [agent] capability, and everything gets configured through the X interface 🫶.
MIB Chart and MIB Chart Editor
You can pick a strip chart, a packed strip chart, or bar graphs 📊. The polling interval is user-specified, and you can chart MIB variable(s) or MIB expressions that use arithmetic operands 🧮. You can plot the actual value, the delta, or the delta/interval, and you can plot multiple MIB expressions from multiple agents at the same time 🤯. It's an X Windows interface, with pause polling and grid options 💜.
MIB Tool
This is an X Windows application for general viewing and 'walking' of MIB trees 🌳. It has GET NEXT and SET options, a window for viewing RFC 1212 MIB definitions, and a command line interface option ⭐.
Application Programming Interface
There's a complete set of APIs so developers can write SNMP applications in character mode or X Windows 🧚♀️💖.
MECHANISM
Management Station uses SNMP and ICMP Echo Request to monitor and control SNMP Agents 🛰️. The network management daemon implements Wollongong's Manager MIB, SNMP over TCP, and the SMUX protocol 🎀.

ABSTRACT
Xnetdb is a network monitoring tool built on X Windows and SNMP, and it also has integrated database and statistic viewing capabilities 📊. It figures out and displays the status of the routers and circuits you tell it to monitor, by querying the designated sites and showing the results 🔍. It can also check the status of certain designated SNMP variables, like a default route for an important router 🛣️. The database side is a vibe too: it can show extra info about a site or circuit, such as the equipment at the site, the contact person(s) for the site, and other useful stuff 📇. And finally, it can gather designated statistical info about a circuit and display it whenever you ask 💖.
MECHANISM
Xnetdb uses SNMP or ping to monitor the things it's configured to watch 👀. It builds a network map on its display dynamically by querying entities and getting their IP addresses and subnet masks 🗺️. A configuration file tells xnetdb which IP hosts you want to monitor 📝.
CAVEATS
While "ping" can be used to monitor hosts, you get more useful results with SNMP 💅.

Okay bestie, this is the XNETMON entry and it's giving network status realness 💖 Xnetmon and xpmon are the two tools that show you how SNMP-capable network elements are doing, and they both use SNMP (RFC1098) to grab the data. Xnetmon draws a schematic network map that shows which elements are up or down 🗺️ and xpmon draws a pen plot style graph of how any arbitrary MIB object (RFC1066) changes over time 📈
MECHANISM 🔥
Xnetmon polls network elements for the status of their interfaces, and you get to control the polling interval ⏱️ Pop-up windows that show the values of any MIB variable run on their own separate polls 🪟 When Xnetmon gets an SNMP trap from a network element, it immediately re-polls that element and all of its adjacent elements so the status is up to date, no cap 💅 The layout of the network map is statically configured.
Xpmon keeps polling (with SNMP) the designated network element for the value of the designated MIB variable, on the interval the user picks. The change in the variable gets plotted on the strip chart, and the strip chart regularly adjusts its scale to the current maximum value on the graph 📊
CAVEATS ⚠️
Polling intervals should be chosen with care so as not to affect system performance adversely. Bestie, pick your intervals carefully or your system's performance could take a hit 💀

sourcelib.ABSTRACT 📊
Xnetperfmon is a XNETMON tool, and it's the one that makes plots of SNMP variables in graphical displays 🖼️ The manager can easily customize the labels, the step size, the update interval, and which variables get plotted, so you can make graphs for fault and performance management 💖 Scales automatically adjust whenever a point to be plotted would go off scale. Iconic 👑
MECHANISM 🌈
The xnetperfmon application talks to remote agents or proxy agents through the Simple Network Management Protocol (SNMP) 📡
CAVEATS ⚠️
All plots for a single invocation of xnetperfmon must be for variables provided by a single network management agent. However, you can have multiple invocations of xnetperfmon active on one display at the same time, or use proxy agents to summarize information at a common point 🫶
BUGS AND LIMITATIONS 🙈

A postscript file describing SPY is located on
ftp.uu.net:/networking/ip/nfs/spy.ps.ZNFSTRACE 🧚
Okay so this is the rpcspy/nfstrace package, and it's described in detail in the paper "NFS Tracing by Passive Network Monitoring", which came out at the January, 1992 USENIX conference 📄
To run it, you'll need either a DEC machine running ULTRIX (with the packetfilter installed in the kernel) or a Sun running SunOS 4.x (with NIT). Or you'll need to do a bit of hacking 🙈
The package is a little different from the version in the paper:
- The handle->name translation facility has been removed. It's just too fragile to include in the general release. If you need it, contact the author directly and they'll be happy to mail you the code 💌
- The output format is a wee-bit different. ✨
- The IBM-RT Enet filter version is also not included, since the author seems to be the only person in the world running it. RTs are really too slow for this anyway 💀
To configure the package, edit the makefile in the obvious (to the author, at least) way.
Note that not all versions of SunOS NIT have working versions of the packet timestamp mechanism. Try to set the -DSTAMPS option in the makefile, and if that doesn't work, take it out 🫠
If you're actually going to use this to gather traces, the author would love to hear from you! Send email, and share your results or traces if your organization allows it. The author maintains a mailing list of users for updates and more, so send mail to be added to it 💜
Happy tracing 🦋

host - look up host names using domain server
SYNOPSIS
host [-v] [-a] [-t querytype] [options] name [server]
host [-v] [-a] [-t querytype] [options] -l domain [server]
host [-v] [options] -H [-D] [-E] [-G] domain
host [-v] [options] -C domain
host [-v] [options] -A hostDESCRIPTION
host looks up information about Internet hosts or domains, and it's iconic at it 🔍 It gets this information from a set of interconnected servers spread across the world. By default, it simply converts between host names and Internet addresses. But with the -t, -a and -v options, it can find all of the information about hosts or domains that the domain nameserver maintains 💖

*/Okay, so this is the new features list, and it's giving "major glow-up" 🦋✨ Every single one of these is a whole upgrade, so let's go through the vibes.
PINGs
Okay, bestie, there are literally so many versions of PING out there 😭🏓 Every implementation has its own little pile of extra features, so here are a few that are totally worth a peek 👀
ftp.cc.berkeley.edu:pub/ping: this one has duplicate packet detection, Record Route, the ability to specify a data pattern for packets, flood pinging, an interval option, Multicast support, etc. 🫶nikhefh.nikhef.nl:/pub/network/rping.tar.Z:rpingis basically PING's cooler cousin 💅 It only sends a single probe packet to test whether a destination is reachable. As an option it uses the loose source routing facility to show the roundtrip route the packet took 🗺️ Multiple addresses of remote hosts get tried until one responds, and as an option, each of multiple addresses can be probed unconditionally. It also has a patch for making loose source routing work if you're on a SUN with an OMNINET ethernet controller 🙈
VRFY
vrfy.tar.Z (Version 921021)Okay, vrfy is giving "email detective" 🔍💌 In its simplest form you hand it an address like user@domain, and it figures out the MX hosts for domain, then issues the SMTP command VRFY at the primary MX host (or all of them, if you ask nicely). If there are no MX hosts, it goes to domain itself. Without domain, it goes to localhost.
It gets even more iconic from there: it can recursively expand forward files or mailing lists, and it can detect mail forwarding loops 🔁 Full-blown RFC822 address specifications are understood (main character energy, no cap). Syntax checking can happen locally or remotely, and there are options to use alternative protocol suites if you need them, plus lots of verbose output if you want to see everything 🧚 There are obvious limitations, but honestly on average it works pretty well 💖 Needless to say, you need internet access (nameserver and SMTP) for this one 🌐 See the man page and the extensive documentation in the source for further details.

The synopsis, as a man page would have it:
NAME
xnetload - ethernet load average display for X
SYNOPSIS
xnetload[-toolkitoption ...] [-scale integer]
[-update seconds] [-hl color] [-highlight color]
[-jumpscroll pixels] [-label string] [-nolabel] hostOkay, so xnetload is a little display that shows the ethernet load average for a specified host 📊 The graph is scaled from 0% to 100%, where 0% means 0mbs and 100% means 10mbs. It updates periodically, and it's giving very "watching the traffic roll in" energy 🌊 Quick heads-up, though: the host you point it at must be running rpc.etherd ⚠️
DESCRIPTION
The xnetload program displays a periodically updating histogram
of the ethernet load average for the specified host. The resulting
graph is scaled as 0% to 100%, where 0% corresponds to 0mbs and
100% corresponds to 10mbs. NOTE: The specified host must be
running rpc.etherd.This program has been run using X11R4 and X11R5, under the following operating systems:
- SUNOS 4.1.0
- SUNOS 4.1.1
- ULTRIX V4.2
- IRIX 3.3.2
Assuming the Imake templates and Rules are in order and in the proper place on your system, these programs should compile and link straightforward by running the following sequence:
xmkmf
makeThen, as root, issue the following:
make install
make install.manThen, on your host system (or on any other system you can rlogin or rsh into), start the etherd daemon with the following (must be root):
/usr/etc/rpc.etherd le0 &where le0 is the mnemonic for the primary ethernet interface 🔌
To start the xnetload program, the following command line is suggested:
./xnetload -hl red host &where host is the name of any reachable network node (including LOCALHOST) that is running the etherd daemon. A small xload window should appear on your local display with nine horizontal lines. The label:
"Ethernet Load %"should appear in the upper left hand corner, just below any additional title bars or other decorations provided by your window manager 🎀 If the program comes up without the nine lines, or without the "Ethernet Load" label, then either your resource file is not properly installed in the appropriate app-defaults directory, or you may have picked up the wrong xnetload image. Try re-running make install as root, or be sure to include the ./ in front of the command name.
If it's not working, don't panic 😭 Check the resource file location and the image you picked up first. Then re-runmake installas root, or add the./in front of the command name. Good luck, bestie! 🫶
The following changes have been made to this directory since R3:
- Now use Athena StripChart widget.
- Understands WM_DELETE_WINDOW.

NAME
nettest, nettestd - Performs client and server functions for
timing data throughput
SYNOPSISOkay, so nettest and nettestd are the client and server pair that time data throughput across different IPC methods ⏱️💨 For TCP and OSI connections, nettest makes a connection with nettestd, then does count writes of size bytes, followed by count reads of size bytes. For UDP, nettest performs only writes, and reads are not performed. If you're using UDP, nettestd reads the data packets and prints a message for each data packet it receives 📨 The number and size of the reads and writes may not line up with the number and size of the actual data packets that get transferred, since that depends on the protocol you choose 🤷♀️ And if you append an optional k (or K) to the size, count, or bufsize value, the number gets multiplied by 1024 🧮
This source for nettest and nettestd is provided on an "as is" basis. Cray Research does not provide any support for this code (unless you are a customer who has purchased the UNICOS operating system).
They will gladly take bug reports for nettest/nettestd. Suggested fixes are preferred to just bug reports 💅 Changes to allow nettest/nettestd to run on other architectures are also welcomed. They will try to incorporate bugfixes and update the publicly available code, but they can make no guarantees.

etherck is a simple program that displays Sun ethernet statistics 📈 If you're seeing a high percentage of input errors due to "out of buffers", you can run the iepatch script to patch a kernel that uses the Intel ethernet chip (ie) 🛠️ A back of the envelope calculation shows that a .25% input error rate gives about a 10% degradation of NFS performance if 8k packets are being used. Yikes 😬
In their environment at Legato, patching the ie buffer allocation made the input error rate drop more than 2 orders of magnitude 📉 This was after they had applied other networking fixes (for example, using Prestoserve, and going from thin wire to twisted pair) and pushed a higher load on the server 💪
Note that both etherck and iepatch must be run by root (or you can make etherck setgid kmem) 🔐
Available as:
send EMAIL to: request@legato.com
with a Subject line: send unsupported etherckThe following is part of the 'help' file from the Legato Email Server:
This message comes to you from the request server at Legato.COM,
request@Legato.COM. It received a message from you asking for help.
The request server is a mail-response program. That means that you
mail it a request, and it mails back the response.
The request server is a very dumb program. It does not have much
error checking. If you don't send it the commands that it
understands, it will just answer "I don't understand you".
The request server has 4 commands. Each command must be the first
word on a line. The request server reads your entire message before
it does anything, so you can have several different commands in a
single message. The request server treats the "Subject:" header line
just like any other line of the message. You can use any combination
of upper and lower case letters in the commands.
The request server's files are organized into a series of directories
and subdirectories. Each directory has an index, and each
subdirectory has an index. The top-level index gives you an overview
of what is in the subdirectories, and the index for each subdirectory
tells you what is in it.
The server has 4 commands:
"help" command: The command "help" or "send help" causes the server to
send you the help file. You already know this, of course,
because you are reading the help file. No other commands are
honored in a message that asks for help (the server figures
that you had better read the help message before you do
anything else).
SEND a request to Legato to get the rest of the help file!NETCK
netck is a shar file that contains the sources to build "netck", a network checker that uses the rstat(3R) protocol to gather and print statistics from machines on the network 📊 It's super useful for figuring out which parts of which machines could be potential NFS bottlenecks 🔎 To get this file, send email to the request server with the command send unsupported netck.
