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.

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.)

   0 = Opened (Destination Host opened a connection and was
   accessible to user.)

   * The UCLA IMB-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.
