I've been reading about this today as I didn't know too much about how it works. I have to say I like it!! I like it a lot!! In reading about this it looks like you can also use encryption that is not easily breakable to keep just anyone from logging in or brute forcing in. I was going to post this link in the "how to/faqs" but I guess it would have to be moved there if deemed by the mods. Here's a couple links to help you all starting up with SSH and tunneling hxxp://www.putty.org/
hxxp://www.bitvise.com/download-area
It looks like the putty site has a couple programs one of which is "putty" and the other is "bitvise tunnelier" (posted by Jim Bass in the how to/faqs). It also looks like it includes a 30 day free SSH server which I saw mentioned in the "how to proxy IHUB" write up...they said you had to pay for one if I read it right. WinSSHD is a 30 day free trial. The bitvise site has a TON of information on how to set this up and explains it rather easily. I'm going to be searching for some FREE ssh servers. I'll post 'em when I find some.
EDIT*
These are not tested by me BUT listed as FREE ssh servers. Please test them out and post back if they are not free.
