I know this is true -- it's a problem because there are incompatible versions of TALK out there. Specifically, it seems there was a change between the 4.2BSD talk/talkd and the one in 4.3BSD. I have a few questions: does the current TALK daemon support both the old and new versions? And what about the client? As far as I can make out, the new talkd can tell the difference between the two protocols, and when a remote user requests a connection, the local TALK daemon figures out whether they are TALKing 4.2-style or 4.3-style, and then tells the local user to run one of two programs, either /usr/ucb/talk or /usr/old/talk. All this aside, I have never seen this work with the 4.2 TALK, only the 4.3 flavor. Is there anyone out there running a system which can talk in both styles, and deal with incoming and outgoing TALK requests? -- Mark Towfigh, Racal InterLan, Inc. towfiq@interlan.Interlan.COM W: (508) 263-9929 H: (617) 488-2818 uunet!interlan!towfiq "The Earth is but One Country, and Mankind its Citizens" -- Baha'u'llah
