$ ssh -D 9999 username@ip-address-of-ssh-ser ver
This will create a SOCKS proxy on port “9999″ of your computer (localhost). This is a secure tunnel to the server. Now all you have to do is set the preference in Firefox to use a SOCKS proxy. The proxy is, “localhost”, with the port 9999.
Comments
Set "network.proxy.socks_remote_dn s = true" in about:config in Firefox browser. This makes it so that DNS is handled by the remote end of the tunnel as well.
