http2tcp tunnel

The http2tcp tools allow to tunnel tcp connections (presumably ssh) via syntactically correct http requests. It is designed to work in the presence of so-called "transparent" store-and-forward proxies disallowing POST requests.

It also turned out to be useful to stabilise connections where the client's internet connection is unreliable (frequent long network outages, rapidly changing IP address, etc).

http2tcp-server acts as a scgi server and so can be scgi-mounted in the configuration of your web server. It is implemented using the wsgitools.

http2tcp-client is a stand-alone program realising a tcp connection via http to the server. The intended use is to have it as ProxyCommand in your ssh configuration file.

The latest release of http2tcp is 0.5 (Changelog). It is freely available and may be distributed under terms and conditions of a 3-clause BSD-style licence. You can either download it as tar ball, browse its contents, or install it as a FreeBSD port.

The http2tcp tools are also available via anonymous git. Just use the following command.

git clone git://isilmar.linta.de/aehlig/http2tcp.git

For any questions or bug reports please feel free to contact me (Klaus Aehlig). Patches and pull requests are welcome.
