This directory contains talk and talkd that talk to 4.2 machines. You must use
/usr/old/talk and have inetd running talkd to talk to 4.2 machines.

Talk consists of two parts:

    talk itself, which is the user interface. Talk initiates the
	 talk requests and negotiates with the suitable talk daemons.

    talkd, the talk daemon. Talkd announces an invitation to talk
	 to a user on its' local machine and acts like a rendezvous
	 point for inter-machine talks. The socket address's of
	 the invitING talk process is kept at the local talkd of
	 the invitEE. Talkd must run as root, and should be forked
	 off on boot along with the other daemons. There is
	 no provision for automatic restart of talkd. If for
	 some reason it dies, it must be restarted by hand. Since
	 talkd opens a special addresses socket (517 at the present 
	 time), the first talkd to run will lock out any other
	 talkd. The locked out talkd will sit and bitch every
	 15 seconds for about five minutes, so don't leave it running.


So, to install:

	run 'make install' from the top of the talk source directory.
	The install will fail if an older version of talkd is still
	running. If it does fail because of a 'text file busy' error,
	kill the old talkd and 'make install' again.

	Make sure talk entry in /etc/inetd.conf has proper path (/usr/old/talk)
	and send a HUP signal to inetd(8) if inetd.conf is changed.

	Try talk. If it doesn't wrok, check inetd.conf entry.
