February, 1975, Survey of New-Protocol TELNET Servers It has been two been depressing network has been list (with host and a half months since our last survey, and it has to note that "progress" toward an all-new-protocol even slower than previously. Changes since the last 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 at various times, plus a What is reported here is by the new-Protocol User were gathered via a surveying program run few manual checks to fill out the data. the way the various servers work as seen 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 NewProtocol 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.
