I have it setup so ssh does not ask me for a password. Not really 
familiar with any alternatives to this but I can help you with ssh.

Generate a key:

ssh-keygen -t dsa

It will ask you for a passphrase. If you leave it blank your private key 
will be unprotected. If you set the passphrase you will need to start 
ssh-agent and add your keys before you do the Xnest.

Next copy your public key to the known_hosts file on the target machine.

cat ~/.ssh/id_dsa.pub |ssh servername "cat >>~/.ssh/known_hosts"

(That command looks ugly but it was my attempt at not clobbering the 
known_hosts file if there already is one) Now "ssh servername" should 
login without a password. If you set the passphrase it will still ask 
you for that. To help with that you need to start the agent and add your 
keys.

ssh-agent
ssh-add

Then, run "ssh servername". It shouldn't ask you for a password or 
passphrase.
