I have 2 servers, A and B. I want to create a tunnel from my system to server B but I have some limits to do this. So I have to first tunnel to server A and from server A to server B. My goal is to have a SOCKS Proxy to browse the web.

How can I do this?

I am showing you a very basic way to do it. Here I am assuming that B is directly accessible from A. There may be variations according to various situations.

On A:

ssh -D socks_port B

This will open up the port socks_port on A as a SOCKS proxy.

On your system:

ssh -L local_port:localhost:socks_port A

This will forward local_port on your system to port socks_port on A.

Then you can configure your browser to use SOCKS proxy on socket localhost:local_port


A one-liner would look like this:

ssh -t -L 1234:localhost:5678 FIRSTHOST ssh -D 5678 SECONDHOST

where FIRSTHOST and SECONDHOST have to be replaced by your hosts’ names or IP addresses.

In your browser you have to enter a socks proxy as:

localhost:1234

Thanks, Using this command I have to first run command ssh -D socks_port B on server A. Right? –  hpn Dec 9 '11 at 11:21
    
It doesn't work. I can't browse the web. It only asks password of server A and not B(I think it should ask the passwords for both servers because server A should connect to server B). –  hpn Dec 9 '11 at 11:32
    
@hpnik +1 for your first comment. I am sorry. I think you are right in the first comment. First you need to open up the port on A as SOCKS proxy with -D. I am updating my answer because then my ssh command will also change. –  Sachin Divekar Dec 9 '11 at 11:40
    
Thanks, Is it possible to write both commands in one line? –  hpn Dec 9 '11 at 11:48
    
@hpnik try ssh -t -L local_port:localhost:socks_port A ssh -D socks_port B –  Sachin Divekar Dec 9 '11 at 11:50
