To perform agentless discovery of a remote UNIX host, Veritas Operations Manager does the following:

Uses Secure Shell (SSH) to send the discovery script to the remote host.
Runs the discovery script on the remote host.
Saves the output of the script to a data file on the remote host in the /var/tmp directory.
Uses SSH to get the oputput on to the Control Host.
Deletes the files from the remote host that it used for discovery.

To perform this discovery process, Veritas Operations Manager requires a non-root user account for the remote host. Privileged access is required to discover some information.

See Requirements for agentless discovery of UNIX hosts.
