How do I remove Network Manager?
WirelessNetwork Manager is a service for Linux which manages various networking interfaces, including physical such as Ethernet and wireless, and virtual such as VPN and other tunnels.
While Network Manager is an excellent service for managing the daily requirements of a user's computer, its effects are typically non-optimal for a testing environment. Because of the extra variables it introduces into the state of a test machine's networking configuration, it can be especially difficult to integrate with CDRouter, which also controls network interfaces. Due to this conflict, we recommend removing Network Manager from computers running CDRouter.
Before you begin, please be aware that your LAN interface may require manual configuration after Network Manager has been removed from your system. If you do not have Internet access from another system, you may wish to learn how this process works before completing the removal process. This article discusses how to manually configure network interfaces under several Operating Systems.
