Hmm, I created a script called /usr/local/etc/rlogind.issue :

	#! /bin/sh
	if [ -r /etc/issue ]
	then
		/bin/cat /etc/issue
	fi
	exec /etc/rlogind $@

I then modified the inetd.conf file with the line:

rlogin	stream	tcp	nowait	/usr/local/etc/rlogind.issue	rlogind

and then did % inetd -c

Then, rlogin <my-host-name>

the /etc/issue message gets printed and then I get my prompt back (i.e. the
exec doesn't happen).

I did exactly the same thing with the telnetd and the /etc/issue message 
gets printed and the login prompt appears.

Any ideas?
