Linux Installation Best Practices How you install Linux has an impact on Dell OpenManage Network Manager's installation. Here are some tested best practices: • You can install Linux in its Desktop option, or if you select Basic Server (default) - choose additional packages: XWindows, Basic / Core Gnome Desktop without Gnome utilities, although we suspect any Gnome will work). • Turn off SE Linux in /etc/selinux/config. Change SELINUX=disabled. This typically requires a reboot. • You must install compatibility library from installation media (so it is compatible with installation) compat-libstdc++-33.x86_64 3.2.3-69.el6 @InstallMedia. Also: verify that /etc/hosts points to new name-use the following command and you should see similar output.
