November, 1974, Survey of New-Protocol TELNET Servers

Two months have elapsed since our last survey, and the appearance of additional New-Protocol servers has progressed at the usual snail's pace. The changes in this list are (with host numbers in octal):

SRI-AI (102) now has a New-Protocol server;
SDC-LAB (10) is back on the net and the list;
SDC-CC (110) is coming on the net but status is as yet unknown; USC-ISI (126) and USC-ISIB (226) (formerly ISI-DEVTENEX) now have New-Protocol servers;
SDAC-44 (32) has been removed -- no longer classed as a server host; HAWAII-500 (344) is coming on the net, status presently unknown; LONDON (52) has been added;
BBN-TENEXD is now host 162 (formerly 205).

What follows is an update of the summary and tabulation that appeared in RFC #702.* Is there light at the end of the tunnel?

         total server hosts             37      100%
         no New-Prot server             19       51%
         unknown status (new host)       2        6%
         total New-Prot implem.         16       43%
             New-Prot on socket 27,
                 Old on socket 1 (2)     9       24%
             New-Prot on 1 and 27 (3)    6       16%
             New-Prot on 1 only (3)      1        3%


   *   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 4 Dec. 1974.

(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.
