Tetherbot

Welcome

Wow - i didn't expect this would generate quite this much response. Looks like i've made the front page of Lifehacker and various other blogs.

What is this?

This is an experimental SOCKS proxy and Port Bouncer that should allow you to connect your laptop to the internet using the internet connection (EDGE, 3G or Wifi) of your T-Mobile G1 Cellphone.

What is this not?

It's not really a true "tethering" app. Presently we don't have access to any low level packet APIs so it's impossible (without hacking the lower levels of the phone) to write something that does the kind of NAT connection possible with Windows Mobile phones.

Installation

Read the bit above about no warranty again. This shouldn't damage your phone, but if it does, it's your own fault!

Using the Socks Proxy

The SOCKS proxy will let you connect things like firefox to the internet

Using the Port Bouncer

The port bouncer will let you connect to a single port on a remote host. This works well if you need to establish an SSH tunnel to your home machine.

This should work for TCP only vpns (openvpn can be configured in this mode) but it wont work for Microsoft PPTP (because it's GRE based) or most typical openvpn setups (because they are UDP based).

Credits

Thanks to my wife and boss for their patience while I scramble to get this working.
