Create an ssh key:

ssh-keygen -t rsa -b 2048

Change the filename to "rsync.key"

Don't put in a passphrase.


man sshd. Read the section on Authorized_Keys file format.

Add restrictions to rsync.key.pub: no-agent-forwarding,
no-port-forwarding, no-pty, no-X11-forwarding, perhaps a from
restriction. Make it tight. command = rsync?

Copy rsync.key.pub with the restrictions to your remote machine,
and cat it to the end of ~/.ssh/authorized_keys

When you run rsync, pass it "-e ssh -i /home/jdm/.ssh/rsync.key"

You should have a fairly safe passwordless rsync.
