You can tunnel single ports or run a socks proxy with SSH. Google for SSH forwarding or see the howto below.

=== Example ===

This will open a Socks proxy on port 6969. Configure your applications to proxy through localhost:6969 to use the tunnel.

ssh -D 6969 wadsworth@acidburn.vtluug.org

This opens a tunnel to milton.vtluug.org which is redirected through acidburn.

ssh -L 6969:milton.vtluug.org:22 wadsworth@acidburn.vtluug.org
