SSH tunnels

If you need to web browse securely on an untrusted network or you're behind an overly restrictive web filter, use an SSH tunnel.

ssh -fND localhost:8080

That brings up the tunnel. Any traffic to port 8080 on your local machine will go down a secure SSH tunnel to your remote host. To bring down the tunnel, just kill the SSH process.

To get Firefox to use the tunnel, go to EditPreferencesAdvancedNetworkSettings. Select Manual proxy configuration. Set Socks host to 'localhost' and the PORT to '8080'.

You may also want to send your domain name lookups over the tunnel. Enter 'about:config' in the Firefox URL field. Find 'network.proxy.socks_remote_dns' and toggle it to 'true'.
