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.Dodds                                                           [Page 1]
