HI, you can try to do as user: $ mesg y It could be that you have your messages turned off. Greetz, Sebastian On Sat, 13 Jan 2001, Kent West wrote: I'm trying to get talk to work and can't.

No, #off# is on a separate line; It was on the same line, but I just moved my cursor to beyond it and hit ENTER to move the ntalk . . . line onto a separate line by itself, then restarted inetd with /etc/init.d/inetd restart. tcpdump doesn't seem to be an available command (yes, as root); nor does locate return anything for it.

I've just now tried this on a third box (Debian), from westk in one xterm to westk in another xterm, using the command talk pts/2 (which is the term indicated by the tty command of the second xterm/westk). I still get the same message, but something I may not have noticed on the other machines last night is that before the message Checking for invitation on caller's machine appears, the message Error on read from talk daemon: Connection refused.
