Send Your SSH Public Key To Each Host You Use
if you do not already have a key pair $ ssh-keygen -t dsa send your public key to each host you ssh into $ cat ~/.ssh/id_dsa.pub | ssh you@host 'cat - >> ~/.ssh/authorized_keys2' now you can use ssh-agent and ssh-add to facilitate a "single signon" situation. useful if you're ssh'ing into a bunch of machines all day. google ssh-agent for distribution-specific details.
