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.
