Avoid corporate proxy servers
If like me you work for a company where a proxy server filters the kind of site you visit, you may find it useful to set up a local proxy through a trusted SSH server. In my work I often need to look at security sites, and read about the latest hacking techniques - but I’m almost always blocked because the site could be used for evil purposes. Alternatively, you can use this if you are using a wireless connection, and are concerned about someone hacking your gmail account. It makes perfect sense, but does require a SSH server you can trust.
Download OpenSSH and run the following:
ssh -D 8080 -f -C -q -N -p 22 username@my.server.com
Now configure your browser to use a socks proxy of 127.0.0.1 on port 8080.
