A simple tunneling system designed to make a small footprint HTTP server behind a firewall available on a different machine with a public IP address.
A complete running system would involve three machines:
- A client running a web browser
- The tunneling server running at least python, available on a public IP
- The tunneling client which runs the small footprint program behind a firewall, and also has an HTTP server running on it.
The tunneling server waits for connections from the tunneling client. Once a connection is made, a standard web browser can talk to the tunneling server IP address, and the HTTP connection is tunelled to the web server running on the tunneling client.
The tunneling server program is written in python. The tunneling client program is written in pure C, and compiles to between 50k - 60k on the ARM architecture. It's small enough to run even on the tightest linux distros, such as those that ship on routers and IP cameras.
As of 8/23/2015 this project supports generating a firmware binary suitable for the Tenvis JPT3815w. It could easily be extended to support other platforms. WARNING: reflashing a device with firmware from a source other than the factory is risky at best. If you destroy your device by installing this firmware, it's your problem, your cost, your loss, and no one elses. There are no warranties.
Assuming you are building for an arm device, you will first need a toolchain. Checkout my other project buildroot-arm for an arm based toolchain designed to work with this project.
Assuming you have the toolchain in a folder next to 'vent' (i.e ./vent/../buildroot-arm).
cd vent; #presumably where you downloaded this project make
