SSH Dynamic Port Forwarding
SSH Dynamic Port Forwarding is a way to opening a SOCKS 4/5 proxy server on your local computer and forwarding all of the data to a SSH server on the Internet.
By using SSH Dynamic Port Forwarding you can create an encrypted tunnel to a trusted network, so others have a harder time hacking you.
This is a great feature to have when you are connecting to the Internet from an untrusted network as in an Hotel, Hacker convention or other not secure location.
1. From a console prompt in GNU/Linux type the following to create the SSH Dynamic Port Forward.
root@linux$ ssh -D <localport> <remotehost> where localport Is the local port where the SOCKS server will be listening remotehost Is the remote SSH server where you will forward your connection
root@linux$ ssh -D 1080 firstname.lastname@example.org
You can also setup the forward in Windows using Putty.
You need to create a connection to a SSH Server as usual and in the SSH/Tunnels window setup add a forward using the following information:
Source Port: 1080 Destination: localhost Type: Dynamic
2. Now you need to set up Firefox (works for 3.6) to use this connection:
- In GNU/Linux Edit/Preferences/General/Connection Settings
- In Windows in the Tools/Options/Advanced/Connection Settings
Now on the Connection Settings Windows select the Manual Proxy Configuration and fill the SOCKS fields as follow:
SOCKS Host: localhost SOCKS Port: 1080
Close the windows and you are ready to browse the web thru your secure network. If you use a service to find your public IP, you will see the IP of your SSH server.
