You can create a pair of SSH keys, placing a private key on the server and a public key on the client. This will allow the client to connect to the server using it's public key instead of having to enter a password.

crst53: public/private key exchange is much more secure than using passwords, and much less likely to suffer from brute force attack on the SSH server. The problem is if you don't use a pass-phrase on the key anyone getting physical access to your machine may be able to login through your machine IIUC. –  The Tentacle Aug 21 '09 at 1:09
