Create an SSH SOCKS proxy server on localhost:8000 that will re-start itself if something breaks the connection temporarily

This command will log you into somehost via SSH and then go into the background (-f). From there, you can point e.g. firefox at localhost:8000 as a SOCKS proxy. Autossh will use port 20000 and 20001 to send and receive test data on those ports to ensure the SSH tunnel is still running, and will try to re-start the tunnel if it goes down. Make sure you have ssh-agent running, or passwordless ssh keys distributed between the two hosts.

Alternatives

There are 2 alternatives - vote for the best!

autossh -N -D localhost:1080 myhome.example.net -p 443

You may go to Internet by means of your home ssh server. You must configure your local proxy to send traffic through the proxy. Many programs allows that: firefox, pidgin, skype, gnome, etc.

Your home ssh server must listen in any of the ports permitted by your enterprise firewall. That usually includes 80 and 443.

What others think

this is fantastic and I use it all the time - is autossh a default package on most systems though?

no, autossh is usually an extra install. Very worth it on desktops, IMO.

Comment by sud0er 296 weeks ago

hmm I currently use ssh -i /path/to/publickey -ND localhost:8080 user@proxyserver.com -- if im switching to autossh, how do I setup authentication?

Comment by fotoflo 251 weeks and 2 days ago

autossh -f -i /path/to/key -ND local-IP:PORT User@Server
