Our firewall at work restricts us to only port 80 and no access to SSH – which as you can imagine for a web developer is a pretty big issue. Below I’ll describe the various methods of routing around this crap.
Create a SOCKS5 Proxy with SSH
If your firewall restricts which sites you can visit but you have access through SSH to a remote server, route your browser and other traffic through that server with a SOCKS5 proxy. This is called Dynamic Port Forwarding:
ssh -f -N -D 1080 remote-server
The above command creates a SOCKS5 proxy server on port 1080 of your machine which sends all traffic through remote-server.
Use it with you browser:
Now use the server in Firefox:
- go to Edit -> Preferences -> Advanced -> Network -> Connection -> Settings…
- check “Manual proxy configuration”
- make sure “Use this proxy server for all protocols” is cleared
- clear “HTTP Proxy”, “SSL Proxy”, “FTP Proxy”, and “Gopher Proxy” fields
- enter “127.0.0.1” for “SOCKS Host”
- enter “1080” (or whatever port you chose) for Port.
Use it with git:
You can also configure SSH git origins to work with your proxy:
Open ~/.ssh/config and add
1 2 3
Host bitbucket.org User git ProxyCommand nc -x localhost:1080 %h %p
Now you can just clone/push/pull as normal. See here for more information.
