SSH

 
sshuttle on github

What is sshuttle? Basically, it’s a Python app that uses SSH to create a quick and dirty VPN between your Linux, BSD, or Mac OS X machine and a remote system that has SSH access and Python. Written by Avery Pennarun and licensed under the GPLv2, sshuttle is a transparent proxy server that lets users fake a VPN with minimal hassle.

WARNING: On MacOS 10.6 (at least up to 10.6.6), your network will stop responding about 10 minutes after the first time you start sshuttle, because of a MacOS kernel bug relating to arp and the net.inet.ip.scopedroute sysctl. To fix it, just switch your wireless off and on. Sshuttle makes the kernel setting it changes permanent, so this won’t happen again, even after a reboot.
