Jumpgate is a TCP connection forwarder that provides many enhancements and improvements over the existing programs that do the same thing. It provides an interactive mode that queries the connected party for the forwarding information it needs. Also, there is the option to log the entire forwarded session in a file for later inspection. Furthermore, it can log information about the forwarded session via the syslog(3) facility. If you improve it further, please send me the diffs. As always, published under a BSD-style license, see the included LICENSE file.

Jumpgate has been tested and works on the following platforms:


OpenBSD 3.2 (i386).
OpenBSD 3.1 (i386).
OpenBSD 3.0 (i386).
Solaris 8, thanks to John Weekley and Jesper Peterson.
Solaris 7, thanks to Chris Donovan.
AIX, thanks to feedback from Michael Pacey.

Linux, various distributions and platforms, thanks to feedback from many people.
I have been told that it compiles and runs on Windows using Cygwin, but I have not tested it myself.
