SSH tunnelling and proxies

Hey guys,


I just had a few questions cause I needed to clear a few things up....

An ssh tunnel is basically a secure connection to another computer which a user has an account on right? And all the data sent and received by that computer is encrypted? Also what is the difference in having a shell account on another computer with a private or public key I am a little confused..

If one did connect to another computer using the ssh tunnel, could they then have that computer use a proxy to connect to the internet so basically it would be like using a proxy but having a secure connection to that proxy?

But for this to work would it mean that the user must have an account on the machine the tunnel is connected to right?

 

Yes on a couple of accounts... read more here

I have a tunnel setup on a linksys wrt54g running dd-wrt.. very easy & nice proxy. Word is the dns requests are not encrypted.
