/Admin/SSH-Proxy: Proxychains Allows Any Application to Use a Proxy

My SSH Socks5 proxy[1] works great, especially with the addition of autossh, but unlike most web browsers and Pidgin, many applications (particularly on the command line) just do not have proxy support built in.

Proxychains[2] is a wrapper that redirects all network traffic through a designated proxy. To get it working is very simple. After installing, I made this change to the bottom of /etc/proxychains.conf:

# defaults set to "tor"
# socks4 127.0.0.1 9050
socks5 127.0.0.1 1082

ie. I commented out the default Tor proxy and added my local SSH socks5 proxy which I have placed on port 1082.

Then, for instance, to send my gpodder podcatcher through the SSH tunnel, I just start gpodder in a terminal as follows:

proxychains gpodder&

Then all of gpodder's network traffic (DNS queries included) go out via SSH through my out-of-country server. And now I have restored access to many blocked podcasts, PGP key servers, and no doubt many other things as they come up. I have been looking for something like this for years.
