[gobolinux-users] OpenSSH SOCKS difficulty

Having tested it today, I found that I can get the same "blank page"
results if I have the proxy settings wrong in Firefox. Make sure you
put the proxy in the SOCKS Host section of Firefox's connection
settings rather than HTTP Proxy.

I think I did the same thing at first, although I didn't remember it
when reading your email. It seemed like HTTP proxy would be the
correct setting, but I tested the SOCKS settings with WinPCap to make
sure it was really using the SSH tunnel for everything. If you set
network.proxy.socks_remote_dns to true in about:config, even your DNS
requests will be routed so people eavesdropping on your local
connection won't be able see the domain names you are requesting.

Anyway, make sure the settings look something like this and you should
be all set: http://thinkhole.org/wp/wp-content/images/firefox-connection-settings.gif.
