Network Working Group Ellen Westheimer RFC #293 BBN NIC #8303 18 January 1972 Categories: F, G.3 Updates: RFC 288 Obsoletes: None NETWORK HOST STATUS This RFC reports on the status of most Network Hosts from January 3 to January 15. 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) 8* SDC IBM-370/155 13 Case PDP-10 15 Ames/(Paoli) ILLIAC-(B6500) 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: Network Address Site Computer ------- ---- -------- 7 Rand IBM-360/65 73 Harvard PDP-1 12 Illinois PDP-11 19 NBS PDP-11 The tables on the next two pages summarize the Host status for this period. ______________ [Page 1] *The SDC site is currently replacing their IBM 360/67 by an IBM 370/155. This site therefore is temporarily without any permanent Host on the network, and for this reason was not included in the daily testing for the preceding two weeks. **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. < In the original, the tables on this and the following page were typed > < in "landscape" format. For this online version the tables are > < compressed horizontally to fit on a "portrait"-oriented page > "STATUS OR NETWORK PREDICTION" ADDRESS SITE COMPUTER STATUS OR PREDICTION OBTAINED FROM ------- ---- -------- -------------------- ------------- 1 UCLA SIGMA-7 Server Jon Postel 65 UCLA IBM-360/91 Remote Job Service now, Bob Braden Telnet in April 2 SRI(NIC) PDP-10 Server John Melvin 66 SRI(AI) PDP-10 "Soon" Len Chaiten 3 UCSB IBM-360/75 Server Jim White *5 BBN(NCC) DDP-516 Never Barry Wessler 69 BBN(TENEX-A) PDP-10 Server Alex McKenzie *133 BBN(TENEX-B) PDP-10 Server(Exper.)

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.
