RFC 1792
TCP/IPX Connection Mib Specification
TCP/IPX Connection MIB Specification 🎀
RFC 1792 🦋 Network Working Group Author: T. Sung, Novell, Inc. 💅 Category: Experimental 🧪 Date: April 1995 🌸
This RFC doesn't list anything it obsoletes or updates in its title block, so it's a standalone experiment bestie 🫶
Status of This Memo ✨
Okay so this doc is an Experimental Protocol for the Internet community 🧪 It is NOT an Internet standard of any kind, so don't treat it like one 🙈 The authors are literally asking for discussion and suggestions to make it better 💖 And the distribution of this memo is unlimited, so share it with everyone 🌈
IESG Note:
The Area Director for Transport Services at the Internet Engineering Steering Group left a comment 📝 This memo is an individual product of the author, not a group effort 💜 They're also asking for implementation experience, especially on how well these protocols work in dual-stack environments 🔥
1. Introduction ✨
Okay so the classic setup is that TCP and UDP run over IP 🌐 STD 17, RFC 1213 defines the TCP connection MIB object and the UDP listener object with that assumption baked in 💅
Here's the problem 💀 When TCP and UDP run over IPX instead, the tcpConnTable and udpTable objects from RFC 1213 just don't work, because they define the address as type IpAddress 😭 IPX addresses don't fit in there, so we need brand new objects that can actually describe TCP and UDP connections over IPX 🦋
So the new MIB objects are tcpIpxConnTable, udpIpxTable, tcpUnspecConnTable and udpUnspecTable ✨ They're meant to be used in place of tcpConnTable and udpListenerTable when TCP and UDP are running over IPX 🫶
2. Objects 🧚
Here's the whole MIB module, copied exactly as written 💜
TCPIPX-MIB DEFINITIONS ::= BEGIN
IMPORTS
OBJECT-TYPE
FROM RFC-1212;
-- IPX address type.
-- First 4 octests are the network numbers and the last 6
-- octests are the node numbers. In ascii, it is represented
-- as hex digits, as in: nnnnnnnn:mmmmmmmmmmmm
IpxAddress ::= OCTET STRING (size (10))
-- TCP/IPX MIB object idenfifiers
novell OBJECT IDENTIFIER ::= { enterprises 23 }
mibDoc OBJECT IDENTIFIER ::= { novell 2 }
tcpx OBJECT IDENTIFIER ::= { mibDoc 29 }
tcpxTcp OBJECT IDENTIFIER ::= { tcpx 1 }

-- IPX.

"A table containing information specific on
TCP connection over IPX network layer."

tcpIpxConnEntry OBJECT-TYPE
SYNTAX TcpIpxConnEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"Information about a particular current TCP
connection over IPX An object of this type is
transient, in that it ceases to exist when (or
soon after) the connection makes the transition
to the CLOSED state."

DESCRIPTION
"The state of this TCP connection.
The only value which may be set by a management
station is deleteTCB(12). Accordingly, it is
appropriate for an agent to return a `badValue'
response if a management station attempts to set
this object to any other value.
If a management station sets this object to the
value deleteTCB(12), then this has the effect of
deleting the TCB (as defined in RFC 793) of the
corresponding connection on the managed node,
resulting in immediate termination of the
connection.
As an implementation-specific option, a RST
segment may be sent from the managed node to the
other TCP endpoint (note however that RST
segments are not sent reliably)."

used. See tcpUnspecConnTable for connections in
the listen state which is willing to accept

ENDAcknowledgement 🙏
okay so big thanks to Greg Minshall and Dave Piscitello for their assistance 🫶 the author really wanted to shout them out, and that's so sweet of them to be named ✨
Security Considerations 🔐
ngl this one is short and sweet: security issues are not discussed in this memo 🙈 the doc just doesn't get into security at all, full stop.
