Neither of us are. But this is the basic problem:

daemon is a function used in system startup scripts.
inetd is started with a startup script that uses daemon.
telnet is spawned by inetd.
if daemon sets a max limit for core dumps to 0, this will affect telnet
sessions.

And as the startup script for SSH that I had used the daemon function call,
the same applied to it.

If the shell which is spawned by telnet or ssh has a max coredump limit of 0,
so will the MUD.

Make sense?
