Hello,

i prefer ssh with key. Remember: you must copy the public key to server to use ssh with key.

Well... Yes what matthias said is right... I also do prefer SSH tunnel with a key... Reason: Take a look at this article named SSH Host Keys as a protection against Man-In-The-Middle Attacks by Brian Hatch...
