If I understand you correctly, you're asking how the worker nodes know what to update? The simplest answer is that "yum" deals with all that. If you set up a local repo mirror, then that machine should share out that repo directory via http or ftp. You would sync that with an upline mirror, either via ftp or rsync. Then on the worker nodes, you would create a custom repo file in /etc/yum.repos.d pointing to your local repository. Then the worker nodes could just run a "yum update" and they would get all the updates they need. It will do all the version checking, and all you have to worry about is keeping your server's local mirror up to date. -- Spiro Harvey Knossos Networks Ltd 021-295-1923 www.knossos.net.nz
