SEPTEMBER, 1974, SURVEY OF NEW-PROTOCOL TELNET SERVERS

LAST MONTH'S SURVEY PRODUCED A GRATIFYING AMOUNT OF FEEDBACK CLARIFYING THE STATUS OF SEVERAL SITES; HOWEVER THERE HAVE BEEN VERY FEW CHANGES IN THE STATUS OF HOST SERVERS. THE CHANGES IN THIS MONTH'S LIST, IN NUMERICAL ORDER (HOST NUMBER THROUGHOUT ARE OCTAL):

UCLA-NMC IS NO LONGER A SERVER; HOST 205 IS NOW BBN-TENEXD, A NEW SYSTEM (BBNB) IS NOW HOST 61; RAND-RCC WAS ACCIDENTALLY OMITTED FROM THE PREVIOUS LIST; SDC-LAB HAS BEEN TEMPORARILY ELIMINATED FROM THE LIST UNTIL IT RETURNS TO THE NET; I4-TENEXA (117) IS NOT A SERVER--KI4B-TENEX (217) IS, AND HAS BEEN ADDED TO THE LIST; AMES-67 FIXED A BUG, REVEALING TO THE WORLD THE NEW-PROTOCOL SERVER (NO OPTIONS) THAT WAS THERE ALL ALONG; ISI-DEVTENEX (226) AND USC-ECL (327) HAVE BEEN ADDED.

WHAT FOLLOWS IS AN UPDATE OF THE SUMMARY AND TABULATION THAT APPEARED LAST MONTH.* THERE IS STILL A LONG WAY TO GO TO 100% NEW-PROTOCOL IMPLEMENTATION.

TOTAL SERVER HOSTS 34 100% NO NEW-PROT SERVER 21 62% TOTAL NEW-PROT IMPLEM. 13 38% NEW-PROT ON SOCKET 27, OLD ON SOCKET 1 (2) 6 18% NEW-PROT ON 1 AND 27 (3) 6 18% NEW-PROT ON 1 ONLY 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 23 SEPT. 1974. (2) THESE ARE THE SITES WHOSE OPERATION IS 100% CORRECT ACCORDING TO ALL PROTOCOL 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.

KEY TO SERVER STATUS TABLE:

I# OPTION # IMPLEMENTED INCOMING TO USER (SERVER SAYS "WILL #")

O# OPTION # IMPLEMENTED OUTGOING FROM USER (SERVER SAYS "DO #") (# IS OPTION NUMBER IN NEW PROTOCOL. ALL OPTIONS IMPLEMENTED BY ANYONE ARE: 0 TRANSMIT-BINARY 1 ECHO 3 SUPPRESS-GO-AHEAD 6 TIMING-MARK)

NOTE: * THERE APPEARS TO BE A MINOR BUG IN SU-AI'S SERVER: IT SEEMS TO SEND AN IMPROPER RESPONSE TO A REQUEST FOR OPTION 0.
