Network Working Group Ellen Westheimer NIC # 11013 BBN RFC # 366 11 July 1972 Categories: F. G.3 Updates: RFC #362 Obsoletes: None

                        NETWORK HOST STATUS
   This RFC reports on the status of most Network Hosts from June 19

to June 30.

   No testing was done on June 20 due to an attempt to install the

new IMP system.

   Several Hosts are currently excluded from the daily testing as

they are presently intended to be users only. Included here are the Terminal IMPs, which are presently in the Network (AMES, MITRE, RADC, NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, 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
          138             Lincoln               TSP
           12             Illinois              PDP-11
           19             NBS                   PDP-11
           23             USC                   IBM-360/44
   The 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. [Page 1] NO.

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.
