Installation of RALUS ( Remote Agent for Linux and Unix Server) fails while performing initial system check.

Problem

Installation of RALUS ( Remote Agent for Linux and Unix Server) fails while performing initial system check.

Error Message

Attempting /usr/bin/rsh with servername.local ... cannot /usr/bin/rsh to servername.local.
Initial system check failed.

Cause

1) This issue can occur when the install script is unable to find the hostname in the host address lookup table.

2) This can also occur when attempting to install the remote agent from a user that is not local, such as an Active Directory user.

Solution

1. Log into the system with root privilege.

2. Type vi /etc/hosts  and press letter (i) on keyboard to insert any changes in hosts file

3. Enter IP address and hostname for the system and save the changes.
   
   For example:
127.0.0.1      localhost
10.0.0.1       servername.mylinuxserver.com   servername.

Note: This issue can also be resolved by manually typing the servername when the installer prompts for the servername. But its preferred to have the entries of the servername in the host file for hostname lookup.

Solution 2: Log on as a user that is local.

1. Log off of the Mac OS non-local user account (Control + Option + Shift + Q)
2. Open the terminal and install Backup Exec Remote Agent for Macintosh Systems as normal.
