Use the Backup Exec installation media to do the following:
If you push-install the Remote Agent, 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 Agent. Refer to your operating system documentation for more information about SSH.
When you install the Remote Agent, Backup Exec creates the beoper group and adds root as a member. The beoper group contains the names of the users who have permission to back up and restore the Linux or UNIX servers. However, if Backup Exec detects an NIS server during the Remote Agent installation, then the beoper group is not created. You must create the beoper group manually on the Linux or UNIX servers on which you want to install the Remote Agent.
