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.

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.
