Summary of supressing "UNIX(r) System V Release 4.0 (joe.foo.com)"
banner on telnet login on a Solaris 2.4 system....

The answer is not a pretty one...
The banner is not in the /etc/motd or /etc/issue file...
It lives in the binary in.telnetd....ugly :-(
It would be nice if SUN had build in.telnetd with some sort of flag to
suppress this...

OPTIONS:
1 -Replace in.telnetd with a public domain version -- not
2 -Recompile it...SUN would have to provide the source code
3 -Edit the binary very very carefully and replace the banner with blanks
4 -get SUN to send me a binary with out the banner...

I am going to push for number 4....

later..

This is a message buried in in.telnetd. I don't think you can get
get telnetd not to do it. You might be able to get a public domain
telnetd like the wu-* stuff, but I haven't done that personally for
a while...

A quick run of "strings /usr/sbin/in.telnetd" shows that this string is
hard-coded into the telnet daemon. To fix it, you'd probably want to
(carefully) modify the string by hand or compile a new telnet daemon.

It's hard-coded in /usr/sbin/in.telnetd. You would have to modify the
program to eliminate the message.
