- Network Working Group E. Westheimer
- RFC #252 Bolt Beranek and Newman
- NIC #7693 8 October 1971
- Categories: F, G.3
- Updates: RFC 240
- Obsoletes: None
-
-
- The purpose of this RFC is to report on the recent status of most
- Network Hosts. During September 27 through September 29 the BBN prototype
- Terminal IMP (Network Address 158) was in-accessible due to hardware
- debugging. The Network was, therefore, not examined on these days.
-
- Three Hosts which were not officially able to act as Server's at the
- time of RFC #240 are now able to do so. These Hosts are:
-
- NETWORK
- ADDRESS SITE COMPUTER
- ------- ---- --------
-
- 2 SRI (NIC) PDP-10
- 6 MIT (Multics) H-645
- 9 HARVARD PDP-10
-
- The Harvard PDP-10, however, has limited core space. They will,
- therefore, run the Telnet program only occasionally.
-
- The following two tables summarize the information on the Host status
- for September 30 - October 8.

- where
-
- D = Dead. (Destination Host either dead or inaccessible [due to network
- partitioning or local IMP failure] from the BBN Terminal IMP).
-
- R = Refused. (Destination Host returned a CLS to the initial RFC.)
-
- T = Timed out. (Destination Host did not respond in any way to the initial
- RFC, although not dead.)
-
- 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.)
-
- * The UCLA IBM-360/91 currently has Remote Job Service (NETRJS), but has
- not implemented a full server Telnet System. The BBN Terminal IMP is
- not equipped to test NETRJS; however, we are assuming that receipt of
- the UCLA explanatory message indicates that NETRJS is also functioning.
-
- # These sites advertise that they may not have their system available at
- these time.
