This was working beautifully till i upgraded to ubuntu 9.4. With this, thunderbird suddenly stopped working and gave some errors about not being able to connect to the proxy. I removed the proxy settings in thunderbird and ran tsocks thunderbird, it is connecting now. I used to run an ssh tunnel and access my mail at work using thunderbird over it.

I tried it with firefox and a few other programs and it is working beautifully. Sorry for all the questions, and thanks for all your help.....

Try it with a different browser maybe firefox or ephipany. Don't background your ssh connection, do you get any error messages there?

I can log into the remote machine via ssh etc, but if I ssh into the machine and then run tsocks konqueror (for example), the IP in konqueror is not the remote address. It does seem like tsocks.conf is important as I get a segmentation fault if I hash out the server, port and type lines. Any ideas? Thanks for the reply Nick.

If you can ssh from your vpn connection to an external machine thats how you setup your tunnel to the outside. Then tsocks just wraps your application and connects to your ssh dynamic proxy tunnel.

Unfortunately I just can't seem to get tsocks to tunnel internet traffic. My connection is via a vpn and uses an IP number rather than a domain name - would that make a difference? I can ssh into the machine and everything works, but for some reason the traffic isn't routed through tsocks. Any ideas? Thanks for the how-to.

You would then ssh to your home machine using the dynamic port 1080. That way when tsocks wraps your application its traffic will go out through the ssh tunnel. ..... So you do need the ability to install tsocks on the local machine and you need to be able to ssh to a remote machine.

Tsocks does not proxy DNS requests without a patch. Indeed firefox has builtin socks and there is foxyproxy which can do some cool things. However it is a bit easier to show how socks works with a browser than with a mail client. I have found it useful in select hotels that block port 25 out. Its much easier to use socks to get around that than setting up multiple outbound servers and doing ssh tunneling, or even setting up a vpn. Although a vpn would be a great permanent solution tsocks is helpful for on the spot type things. Thanks for the comment Robert. Tsocks does not proxy DNS requests without a patch.
