If you are on Linux, you are in luck

, there is a deamon program called tcpd. You just replace the /usr/bin/telnetd with this tcpd in the inetd.conf file, and define the ip addresses in the /etc/host.deny. If you are running on Solaris, you can download the tcpd source file(gnu license) and compile it on your sparc.
