Use Putty as SOCKS proxy

I’ll need 2 programs to achieve this, assuming you already have access to a Linux box and you can connect using putty client. Need S/w packages are-

1. Putty and
2. SeaMonkey Browser

Follow the following steps-

• Run Putty
  
• Goto SSH > Tunnels and configure as required
  • Turn Tick ON- Local port accept connects from other hosts
  • Turn Tick ON- Remote ports do the same (SSH-2 only)
  • Type “8443” (I’ll using port 8443 to create tunnel) into “Source Port” and click “Add”. Upon hitting “Add” button the mid text box is shown as “D8443”
    
• Key point here is to use “DYNAMIC” for destination section
• Now connect to the SSH Server

Now it’s time to fire-up your Mozilla Seamonkey browser and open “Edit > Preference” section as below-

From the new window move to “Proxies” under “Category” and select “Manual Proxy Configuration” and hit “Advanced”

In the new windows dialogue insert “Socks Proxy: localhost and Port: 8443”. Select “SOCK 5”. Click OK and return to browser window.

In the browser address bar type https://ipmonkey.com and voila! you’ll see your linux box IP telling you that you are now browsing through the SSH tunnel a.k.a SOCK Proxy.

There’s a good youtube tutorial where it is explained quite better-

Enjoy!
