Network Working Group Ellen Wentheimer Request for Comments: 255 Bolt, Beranek and Newman Updates: 252 October 26, 1971 NIC: 7696

 This RFC reports on the status of most Network Hosts from October 12
 to October 22.  (Monday, October 11 was Columbus Day.)  During these
 two weeks, the general status of these Hosts remained as it had been
 previously.
 The table on the following page summarizes the daily information on
 Host status for this period.

Wentheimer [Page 1] RFC 255 October 1971

 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.)
    O = 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.
         [This RFC was put into machine readable form for entry]
