Hello and welcome. ;^) Okay. I'm not as familiar as RHEL systems as I used to be, but here's the general outline.
Technically since there's no communication between nodes, then this should be resonably simple. For the remote boxes, you can use ssh. For example, I can run the following command on the remote box named crow: ssh [EMAIL PROTECTED] '/bin/df -k' This will run "df -k" on the box named "crow" as the user "rob". Now it does ask me for a password. I can get around this by generating key pairs. This is explained in section 21.3.4 and 21.3.4.1 of the RHEL system administrators manual: http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/s1-openssh-client-config.html Make sure you do steps 1 and 2 as the same user that's farming out the jobs. Use an empty passphrase. Steps 3 and 4 are done as the target user on the remote machines that will be running the jobs.
