ssh-keygen -t rsa

Do not enter password when prompted. from there,

cd ~/.ssh/ && cp id_rsa.pub laptop.key

Then put that key into authorized_key file on the remote computer. I had an nfs share of my home computer, so I just did it that way. You could use FTP, Thumbdrive, etc.

cat laptop.key >> authorized_keys

Once that is complete, repeat for both machines. You should then have 2 way passwordless communication via rsync & ssh.

here's the script I wrote.

amark="/home/james/.kde3.5/share/apps/amarok/"

This script will sync the directories in the #delare variables section. Change those around accordingly. I know there are other methods, but this method is good enough for what I want to do. Please feel free to email me with a better method. I'm certainly not the most proficient bash scripter.

Oh, one more thing, before I started, I edited /etc/hosts and added the hostname of all computers on my network. That way, all I have to do is type ssh computername instead of ssh ipaddy and no password is needed.
