Network Working Group Ellen Westheimer NIC #10604 BBN RFC #362 28 June 1972 Categories: F, G.3 Updates: RFC #353 Obsoletes: None

                        NETWORK HOST STATUS
    This RFC reports on the status of most Network Hosts from June 5

to June 16. During this period the MIT Math Lab PDP-10 (Network address 198) became a server.

    No testing was done on June 6 due to an attempt to install the

new IMP system. No testing was done on June 9 as the prototype Terminal IMP was being used for software debugging.

    On June 16 the ARPA Terminal IMP (Network 156) was installed in

Arlington, Virginia.

    Several Hosts are currently excluded from 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) on a regular basis for at least two weeks. The only Host in this category is the PDP-10 at Case (Network address 13).

2) Hosts which are currently intended to be users only. Included here are the Terminal IMPs, which are presently in the Network (AMES, MITRE, NBS, ETAC, USC, GWC, NOAA, RADC, SAAC, BELVOIR, ARPA, 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:

        Address                Site                Computer
        -------                ----                --------

           23                 USC                  IBM-360/44
    The tables on the next two pages summarize the 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.

R = Refused (Destination Host returned a CLS to the initial RFC.) T = Timed out (Destination Host did not complete the ICP and open a connection within 60 seconds.) _ *The only service currently offered by the UCLA IBM-360/91 is a Network Job Service (NETRJS), however, the BBN Terminal IMP is not equipped to test NETRJS.
