Network Working Group Ellen Westheimer Request for Comments: #287 BBN NIC: #8273 22 December 1971 Categories: F, G.3 Updates: RFC #267 Obsoletes: None Status of Network Hosts This RFC reports on the status of most Network Hosts from December 6 to December 18. Due to hardware debugging, the BBN prototype Terminal IMP (Network Address 158) was unavailable for most of the two weeks from November 22 to December 6. There was, therefore, no Host status reports for that period. Several Hosts are currently excluded from the daily testing. These Hosts fall into two categories: 1) Hosts which are not expected to be functioning on the Network as servers (available for use from other sites) on a regular basis for at least two weeks. Included here are: Network Address Site Computer ------- ---- -------- 133 BBN PDP-10 (B) 71 Rand PDP-10 13 Case PDP-10 15 Ames/(Paoli) ILLIAC/(B6500) 16 Ames IBM-360/67 2) Hosts which are currently intended to be users only. Included here are the Terminal IMPs, which are presently in the Network (AMES, MITRE, NBS and BBN*). This category also includes the Network Control Center Computer (Network Address 5) which is used solely for gathering statistics from the Network. Finally, included among these Hosts are the following: [Page 1] Network Address Site Computer ------- ---- -------- 7 Rand IBM-360/65 73 Harvard PDP-1 12 Illinois PDP-11 19 NBS PDP-11 The NBS Terminal IMP (Network Address 147) was installed in Washington at the beginning of December.

Wentheimer Request for Comments: 252 Bolt, Beranek and Newman Category: F, G.3 8 October 1971 NIC: 7696 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 inaccessible 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 SITE COMPUTER ADDRESS 2 SRI (NIC) PDF-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.

In compiling RFC #235, I followed the principle that timeliness was somewhat more important than extremely careful editing; this seemed to me to be in keeping with the original RFC philosophy. I am sorry for any embarrassment this may have caused to anyone associated with the Network, and accept full responsibility for the content of RFC #235. I will try to do a better job in the future. Alex McKenzie SITE STATUS Beginning with this RFC, BBN will report on the status of most Network Hosts approximately once every two weeks. The information for these reports will be gained from talking to people at each site, and from experimental "data". These data will be the results of daily attempts to log into each of the Hosts which might be accessible to a Network user; the attempts will have been made from the BBN prototype Terminal IMP at a random time each weekday. Several Hosts are currently excluded from the daily testing. These Hosts fall into two categories: 1) Hosts which are note expected to be functioning on the Network as servers (available for use from other sites) for at least a month. Included here are: Network Site Computer Address 71 Rand PDP-10 74 Lincoln TX2 11 Stanford PDP-10 [Page 1] RFC #240 13 Case PDP-10 14 Carnegie PDP-10 15 Paoli B6500 2) Hosts which are currently intended to be users only. Included here are the Terminal IMPs presently in the Network (AMES, MITRE, and BBN[1]).
