Use the Backup Exec installation media to do the following:
If you push-install the Remote Media Agent for Linux Servers, the RSH (Remote Shell) is used by default. Symantec recommends that you use SSH (Secure Shell) instead. To use SSH, you must enable it before you install the Remote Media Agent for Linux Servers. Refer to your operating system documentation for more information about SSH.
When you install the Remote Media Agent for Linux Servers, Backup Exec creates the beoper group and adds root as a member. Any Linux user that you add to the beoper group gets the permissions necessary to back up and restore the Linux servers.
However, if Backup Exec detects an NIS server during the Remote Media Agent for Linux Servers installation, then the beoper group is not created. You must create the beoper group manually on the Linux servers.
