Be aware that the rest of this guide will require packages which need to be installed from the online repositories. To counter this, disable the startup script of either application or completely remove the packages. It will probably include eth0 (hardwired NIC), lo (loopback interface for the localhost), and something for your wireless card (like wifi0, or wlan0).Ĭonfiguring your network via the CLI will likely interfere with Network Manager or wicd. This will list the interface names for all NICs on your computer. The interface name of cards for different vendors may be different, which is why this step is needed. When setting up your network you will need to know the network interface cards on your computer. You can add hostname and IP addresses to the file /etc/hosts for static lookups. When your system boots it will automatically read the hostname from the file /etc/hostname. To circumvent this you need to add the new name to the hosts file prior to setting the hostname and remove it once that action has succeeded. This is because sudo requires DNS lookups in certain cases and it cannot resolve your newly set hostname. This is needed because otherwise you will need to boot into single user mode and change your hostname in /etc/hosts. If you do this however, make sure you change the /etc/hosts file first. To set the hostname directly you can run hostname newname as root. You can see your current hostname by running hostname. The hostname command allows you to directly query, or set, the hostname from the command line.
