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 servers?); 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% Notes:

* 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.

Tabulation of server status for all server sites:

Note: * These servers return improper responses to some TELNET option requests.
