Tunnel DNS through ssh -D socks proxy

By | 2012/12/19

When using ssh -D to setup a socks proxy, DNS queries and DNS traffic are not sent through the ssh tunnel. However, with Firefox a config change can be made to send DNS traffic through the ssh tunnel. Here’s how it works!


First, establish an ssh proxy:

$ ssh -D 9000 user@host

Then in Firefox, enable a SOCKS proxy to localhost, port 9000 (or whatever port desired). This will enable all web traffic to go through that ssh tunnel.

01_socksproxy


Next in order to also send DNS traffic through the proxy, open a Firefox tab and go to about:config

Change the following value to true:

network.proxy.socks_remote_dns

02_socksproxy

Done!
