RFC 342
Network Host Status
NETWORK HOST STATUS ✨
- Network Working Group 🎀
- Author: Ellen Westheimer, BBN (NIC #10421) 💅
- RFC #342, dated 15 May 1972 📅
- Categories: F. G.3
- Updates: RFC #332
- Obsoletes: None
okay so this RFC is a status report on most of the Network Hosts from April 24 to May 5 🧚 During that stretch, the IBM 360/44 at the University of Southern California (Network Address 23) became a Network user, and literally everyone was excited about it 🔥
Hosts Excluded from Daily Testing 🙈
Some Hosts are currently excluded from the daily testing, and they fall into two groups:
- Hosts that aren't expected to be working on the Network as servers (available for use from other sites) on a regular basis for at least two weeks. Here they are:
Network
Address Site Computer
------- ---- --------
134 MIT-AI PDP-10
13 Case PDP-10- Hosts that are currently meant to be users only. This group includes the Terminal IMPs, which are presently in the Network (AMES, MITRE, NBS, ETAC, USC, GWC, and BBN*). It also includes the Network Control Center computer (Network Address 5), which is used solely for gathering statistics from the Network. And finally, these Hosts are in here too:
Network
Address Site Computer
------- ---- --------
7 Rand IBM-360/65
73 Harvard PDP-1
12 Illinois PDP-11
19 NBS PDP-11
23 USC IBM-360/44The tables on the next two pages summarize the Host status for this period 📊
*The BBN Terminal IMP (Network Address 158) is a prototype and as such is frequently not connected to the Network, but being used to refine and debug the Terminal IMP programs.

D= Dead (Destination Host either dead or inaccessible [due to network partitioning or local IMP failure] from the BBN Terminal IMP.)F= Full (Destination Host opened a connection, informed user that all Network ports were in use, and immediately closed the connection.H= 1/2 Open (Destination Host opened a connection but then either immediately closed it, or did not respond any further.O= Open (Destination Host opened a connection and was accessible to users.)R= Refused (Destination Host returned a CLS to the initial RFC.)T= Timed out (Destination Host did not complete the ICP and open a connection within 60 seconds.)
*The only service currently offered by the UCLA IBM-360/91 is a Network Job Service (NETRJS), however, the BBN Terminal IMP is not equipped to test NETRJS. We are assuming that initial connection to the NETRJS logger indicates that NETRJS is also functioning. #These sites advertise that they may not have their system available at these times. !Rand opened a connection but requested users to logout immediately.
