sixtynine is a small utility that lets you create a simple TCP tunnel between two (otherwise) innaccesible points. To help you understand the point here, I'll explain the main motivation that push me to write sixtynine.

Inside a LAN we have a streamming server (icecast2) that serves music all day. The radio is really cool, and some times we want to broadcast to the rest of the net (ie: the whole world). Because the server runs inside the LAN and it doesn't have an external IP (and we're not admins of the LAN), the only way would be to create a ssh tunnel from a machine that can see the world (has a valid IP) to the server. Some times we don't have ssh access to the sever or we just don't want to create the ssh tunnel (for any reason). Here comes sixtynine in our help: port forwarding in a snap. In the machine that can see the world, we would type:

$ sixtynine -p 9997 -d icecast.landomain:8000 -f

That creates a fast and simple tunnel from local port 9997 to icecast.landomain:8000 and forks into background.

Latest version (cvs, recommended):0.0.3cvs
What's new on this version?

• Threads instead of separate process for each connection. This should speed things a little.
• Configuration files! now you can forward several ports to several machines with just one instance of sixtyine.

And for the next version?

• ... who knows... ;-)

Download it now!

• From chileforge.cl file's section
• or from cvs

F.A.Q

• Q: How can I stop sixtynine after forking it to the background?
• A: Sixtynine leaves a pid file when it's in the background, just kill it with a SIGQUIT singal:kill `cat sixtynine.pid`
