Network Working Group D.W. Dodds Request for Comments: 669 BBN-TENEXA NIC: 31435 December 4, 1974 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% 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 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.
