Leapfrog 1.0. Leapfrog will anonymize and redirect any port. It can be used to work around firewall configuration and other issues requiring a port redirect. For example, you have a firewall that does not allow telnet (23), but it does allow http (80). Set leapfrog up on the other side of the firewall to listen on port 80 and send to 23, then telnet to port 80 of the leapfrog machine and you will ricochet to the machine you wish to connect. You will have the Leapfrog machines' IP and MAC addresses. It supports unlimited users (well, limited by memory). Leapfrog can be chained, reconfigured on the fly, and customized to change ports/machine redirects without the need to log into the box. It can be configured (with little work) to remove all traces of itself from disk after being loaded, or it can be configured to log everything (default). It supports colors and some basic admin tools. It is very fast. Leapfrog compiles on Solaris 2.6, 2.7, x86 (2.6, 2.7), Linux with pthread libs,...
