===Part 2: How do we Manage Runlevels?===

It is common that these Linux servers are separated (for security purposes) and they are '''run in Command-Line mode only'''. Running these Linux/Unix servers in '''Graphics Mode will make them more vulnerable to penetration from hackers, etc.''' Therefore, it is common that the Linux servers are CLI <u>only</u>, but the Workstations that connect to them within the network are GUI. Therefore, it is important that a Linux/Unix system administrator understand to switch to these different "run-levels". ]]|}
Running servers in graphical mode will make your system most likely to be penetrated. The X-windows framework can be vulnerable to attacks when these servers are connected to the Internet. This is why when you install server versions of Linux, they work in text-based mode only. Desktop versions of Linux are then installed on workstations (working in graphical mode) that connect to the server (for security reasons).
