[SOLVED] Encrypted Socks Tunnel with SSH

many people use command

$ ssh -ND 8080 user@host

to protect internet traffic by tunneling to a safe location (like home server).
This should be done from client side and after connection is established, one can use localhost:8080 as a proxy server in web browser.
The question is following: is it possible to reverse direction of tunnel initiation? That is, establishing tunnel from the server side (with autossh for example) and then, similarly to above example, using localhost:8080 on the client side as a proxy?
Or should I run something as polipo on a server and then use simple tunneling with -R switch?

Re: [SOLVED] Encrypted Socks Tunnel with SSH

Yes, and it is called ssh reverse tunneling.  Google has sever good links based on that search term.

Re: [SOLVED] Encrypted Socks Tunnel with SSH

Thank you, ewaller.
Actually I did tunneled proxy once by establishing first reverse tunnel, like

$ ssh -qNnT -R 3333:localhost:22 mydomain.com 

and then on client side

$ ssh -p 3333 -D 8888 localhost 

but I'm not sure about how -D switch actually works and if it possible to introduce it somehow into first command to make tunnel and proxy forwarding simultaneously.
