+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.

+
+ 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

+
+ O = Open (Destination Host opened a connection and was accessible to

+
+ * 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.
