- Request for Comments: 240 BBN
- NIC #7665 30 September 1971
- Categories: F, G.3 Rand 50ctu
- Updates: none
- Obsoletes: RFC 235
-
-
- SITE STATUS
-
- Due to extensive typographic errors in RFC #235, I have
- decided to reissue the first of our experimental site status reports.
-
- In compiling RFC #235, I followed the principle that
- timeliness was somewhat more important than extremely careful editing;
- this seemed to me to be in keeping with the original RFC philosophy. I
- am sorry for any embarrassment this may have caused to anyone associated
- with the Network, and accept full responsibility for the content of RFC
- #235. I will try to do a better job in the future.

- SITE STATUS
-
-
- Beginning with this RFC, BBN will report on the status of
- most Network Hosts approximately once every two weeks. The information
- for these reports will be gained from talking to people at each site,
- and from experimental "data". These data will be the results of daily
- attempts to log into each of the Hosts which might be accessible to a
- Network user; the attempts will have been made from the BBN prototype
- Terminal IMP at a random time each weekday.
-
- Several Hosts are currently excluded from the daily testing.
- These Hosts fall into two categories:
-
- 1) Hosts which are note expected to be functioning on the
- Network as servers (available for use from other sites) for at
- least a month. Included here are:
-
- Network Site Computer
- Address
-
- 71 Rand PDP-10
- 74 Lincoln TX2
- 11 Stanford PDP-10
-

-
- RFC #240
-
-
- 13 Case PDP-10
- 14 Carnegie PDP-10
- 15 Paoli B6500
-
- 2) Hosts which are currently intended to be users only.
- Included here are the Terminal IMPs presently in the Network
- (AMES, MITRE, and BBN[1]). This category also includes the
- Network Control Center computer (Network Address 5) which is
- use solely for gathering statistics from the Network.
- Finally, included among these Hosts are the following:
-
- Network Site Computer
- Address
-
- 7 Rand IBM-360/65
- 73 Harvard PDP-1
- 12 Illinois PDP-11
-
- The tables on the next two pages condense the information on
- Host status for September 13 through September 24.

- RFC #240
-
-
- where
- D = Dead. (Destination Host either dead orinaccessible (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.)
- 1/2 0 = 1/2 Open. (Destination Host opened a connection but then
- either immediately close it, or did not respond any
- further.)
- O = Open. (Destination Host opened a connection and was
- accessible to users.)
-
- Endnotes
-
- [1] 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.
-
- [2] The UCLA IBM-360 is at the moment only able to handle Remote Job
- Service. BBN is not equipped to test this, but is assuming that
- receipt of their canned message indicates that RJS is also
- functioning.
