How agentless discovery of a UNIX or Linux host works

Last published : Jun 19, 2026
To perform agentless discovery of a remote UNIX or Linux host, Veritas InfoScale 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 output on to the Control Host.
  • Deletes the files from the remote host that it used for discovery.
To perform this discovery process, Veritas InfoScale 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.
