Use sshuttle to be save on the internet

A linux box with

iptables
python
ssh

installed. And you (the client) on this machine must be able to get root (e.g. with sudo).

A second linux box with ssh open (the gateway) and a valid login.

git clone git://github.com/apenwarr/sshuttle

cd sshuttle
sudo ./sshuttle --dns -vvr youruser@silenceisdefeat.com 0/0

All traffic (including DNS-requests) will now be tunneled via SSh to silenceisdefeat.com and then go to the internet. You can check this by surfing to

http://ipchicken.com

with sshuttle started and not started.
