these users to the shell script so they won't have access to anything
but this app.  I would like to restrict the telnet daemon further to
allow only certain user names so they can't do a brute force attack.
In sshd_config I've aways used allowd users setting but I don't see
that in the hpux telnet config.  Any help would be greatly

You can configure the system to only allow telnet connections from
specific hosts through hosts.allow or (x)inetd, but I don't know if it
is possible to restrict login on a per-user basis. Anyway I would
*strongly* recommend using ssh instead. Why is telnet your only option
at the moment? There is an HP-UX port of OpenSSH available from [1].
