, 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
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.
