I set up a quick video tutorial to show how to set up an encrypted tunnel using SSHís dynamic port forwarding (sort of a poor manís VPN) in both Linux and Windows. The tools used are OpenSSH, PuTTY and Firefox, but it should be enough info to allow you to figure out how to set up other clients. Why would you want to do this? Sometime you are on an untrusted network, but have to use protocols that arenít completely secure and you donít want someone else on the local LAN sniffing what you are doing. By using SSH dynamic port forwarding you can create and encrypted tunnel to a trusted network so others have a harder time sniffing passwords and other data as you send it. This is a great thing to do if you are on an untrusted network like at a coffee house or at a hacker convention where everybody and their brother is running a sniffer of some sort.
