Tiny Honeypot (thp) is a simple honey pot program based on iptables redirects and an xinetd listener. It listens on every TCP port not currently in use, logging all activity and providing some feedback to the attacker. The responders are entirely written in Perl, and provide just enough interaction to fool most automated attack tools, as well as quite a few humans, at least for a little while. With appropriate limits (default), thp can reside on production hosts with negligible impact on performance.
