OES 11 source and destination servers. I can manually run rsync using
this command:

rsync -A -X -av --delete /media/nss/VOL1/PROJECTS/*
admin@<ip_address>:: projects

But of course it always prompts for a password. I want to set up a
cron job for this, but first I need to figure out how to automate the
login. All my searching hasn't found a workable solution yet.
Suggestions? Thanks!
