The steps below describe how to install the SCOM agent on Red Hat Linux 5 x64. We don’t like to enroll the agent by using the SCOM Discovery wizard, as you need to enter the super-user (root)credentials and we’re not sure where the application stores those credentials and it’s used for. So we’re still searching for the minimal permissions for the agent to be installed.

It is possile to install the agent, copy the unsigned client-side generated certificate to the SCOM server, sign the certificate on the SCOM server and copy the signed certificate back to the client. Once you have restarted the scx daemon you can use the discovery wizard on the SCOM server to add the server without using super-user credentials in SCOM.

Once you have installed the Cross Platform Cumulative Update 2 for System Center Operations Manager 2007 R2, a newer version of the agent becomes available on the SCOM server in Program Files\System Center Operations Manager 2007\AgentManagement\UnixAgents.
