At least under the FC 18 distro, there was no fancy GUI controls in the Advanced Settings for setting up an HTTP proxy over SSH for Chrome.

To get it all set up:

• Establish and ssh connection to the server to which you want to proxy:
  • $ ssh -D localhost:1234 username@remote.server,  where 1234 is the port number you want to use for the proxy
• Run google-chrome from the command line passing it the proxy setting:
  • $ google-chrome –proxy-server=socks5://localhost:1234

For a while I have been wanting to make the switch, and today I took the plunge.→ Continue reading “Making the Switch to a Standing Desk”
