Pre-installation requirements

Additional pre-installation requirements for UNIX systems
• Make sure that an X Server is available for display and is configured to permit X Client
applications to display from the host on which they are installing the Network Advisor server
(typically, this simply requires that the systems console be present and running with a
logged-in user on the X Server-based desktop session, such as KDE, GNOME, and so on).
If this is a headless unit with no console, refer to “Additional pre-installation requirements for
UNIX systems (headless installation)” on page 10.
• Make sure that the DISPLAY environment variable is correctly defined in the shell with a valid
value (for example, to display to the local console, export DISPLAY=:0.0, or to display to a
remote system that has an X Server running, export DISPLAY=Remote_IP_address:0.0).
You may also need to consider a firewall that might block the display to the X Server, which
listens by default on TCP port 6000 on the remote host.
To display to a remote system, you need to permit the remote display of the X Server by running
the xhost +IP command, where IP is the IP address of the Network Advisor server host from the
X-based desktop of the remote system.
• Make sure you test the DISPLAY definition by running the xterm command, from the same shell
from which you run install.bin. A new X terminal window to the destination X Server display
should open.
• For Linux OS with the SELinux security policy enabled, make sure you complete the following
steps.
1. Disable the SELinux security policy using the setenforce 0 command.
2. Install the application (refer to “Installing the application” on page 8).
3. Enable the SELinux security policy using the setenforce 1 command.
