Setup the *nix Machines:   (We will use rsync with the SSH option to backup these systems.) Enable SSH access to the servers, in server-managerWe need to be able to SSH into these machines without being prompted for a password.  Here is an excerpt from an email that explains this: <EXCERPT> Here's the technique in a nutshell (just tried it out on 3 esmith servers): Let's say that you're working on server 10.0.0.20 and you want to ssh to server 10.0.0.30 without having to use a password. On 10.0.0.20, issue the following command as root:      # ssh-keygen -t dsa  This will prompt you for a location to store the key (use the default) and for a passphrase (leave blank). Next, use scp (secure copy) to move the key to 10.0.0.30      # scp .ssh/id_dsa.pub 10.0.0.30:/root/.ssh/authorized_keys2  This will prompt you for the root password on 10.0.0.30 and will then transfer the key from 10.0.0.20 to 10.0.0.30. It should do the trick. Try it out by running an ssh session from the command line:     # ssh 10.0.0.30  It should let you in without a password. You can scp the ".ssh/id_dsa.pub" file to other servers without having to create a public key for each.  -MD </EXCERPT>
