February, 1975, Survey of New-Protocol TELNET Servers

It has been two and a half months since our last survey, and it has been depressing to note that "progress" toward an all-new-protocol network has been even slower than previously. Changes since the last list (with host numbers in octal):

   SRI-ARC (2) and OFFICE-1 (53) have added logger sockets 27, but with
      Old-Protocol servers (are these forerunners of New-Protocol
   SDC-CC (110) has been removed from the list until it starts operating
      on the network
   LL-67 (12) now has a New-Protocol server on socket 1;
   CASE-10 (15) has departed from the network;
   BBN-TENEX is now host 361 (formerly 105);
   ANL (ARGONNE, 67) has come on the net with Old- and New-Protocol
      servers on sockets 1 and 27, respectively.
   The following is the latest version* of the summary and tabulation of
   server-host Telnet servers.
           total server hosts             36      100%
           no New-Prot server             17       47%
           unknown status (new host)       1        3%
           total New-Prot implem.         18       50%
               New-Prot on socket 27,
                   Old on socket 1 (2)    10       28%
               New-Prot on 1 and 27 (3)    6       16%
               New-Prot on 1 only (3)      2        6%
  • All data in this report were gathered via a surveying program run at various times, plus a few manual checks to fill out the data. What is reported here is the way the various servers work as seen by the new-Protocol User Telnet at BBNA, as of 20 Feb. 1975.

(2) These are the sites whose operation is 100% correct according to

all protocols and conventions, as I understand them.

(3) We realize that some of the servers that appear here as New-

Protocol servers on socket 1 are actually servers which attempt to communicate with both Old- and New-Protocol User TELNETs according to what control sequences are received.
