Network Working Group Ellen Westheimer RFC #267 BBN NIC #7815 22 November 1971 Categories: F, G.3 Updates: RFC #266 Obsoletes None

    This RFC reports on the status of most Network Hosts from November

8 to November 19. On November 18, however, the BBN prototype Terminal IMP (Network Address 158) was inaccessible due to hardware debugging.

    Several Hosts are  currently  excluded  fron  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) for at least two weeks.  Included here
        are:
        Network
        Address        Site             Computer
          71           Rand             PDP-10
          74           Lincoln          TX2
          13           Case             PDP-10
          14           Carnegie         PDP-10
          15           Ames             B6500
          16           Ames             IBM-360/67
    2)  Hosts which are curently intended to be users only.
        Included here are the Terminal IMPs, which are
        presently in the Network (AMES, MITRE, 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
    During these two weeks the Lincoln Labs TX2 Hosts became a Network

User. The SDC IBM 360/67 is now a server.

                                                              [Page 1]

The tables on the next two pages summarize the information on 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.

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 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 times.
