[Samba] Equivalent of "net send" command

[Joshua Beall]

I recall there being a command under linux, that I believe was a part of the
Samba suite, that allowed you to send messages to other machines, like one
would do using "net send" on an XP box, for instance.  I have been trying to
figure out what that command was, but I cannot find it in the docs.  I must
not be looking in the right place!  Can anyone straighten me out?

Thanks!
