Setting/changing the hostname

Introduction

It's different and therefore is irritating. You can see these by running the 'systemctl' command without any arguments. By default it ignores items that are inactive, so you can list all of them with the 'systemctl --all' command.

Initializes network console logging netfs. Mount and unmount network filesystems. To go back to the old way with just using ifcfg scripts you would have to do something like this: The second way, which I tried to figure out this morning is to use NetworkManager from the command line.

This way you avoid having to have a GUI with nm-applet and gnome-control-center and all that hoopla. The tool you use for doing this is called 'nmcli'. Using this you can bring up interfaces, bring them down.

Turn off and on wifi and see the status of connections. To see the status of a connection you can go: To get syntax reminders you can go: So that way lets you manage the connections. Not my favorite type of command line tool, but it seems typical for modern Linux ones. To manage configurations is quite a bit different. Usually at this point you'll just want to pull of the gnome-control-center or whatever to configure it that way.

Now if you want to do it through your favorite text editor The first method is available for Fedora systems, which is enabled by default, and that is by using the 'ifcfg-rhn' plugin for network manager. This is enabled by default and when you make changes to the configuration through the GUI tools then it will often make a ifcfg file you can edit and make changes with.

Since systemd, they are named differently: This abstraction is called the everything is a file concept. Anything in user-space accesses the hardware through its device file. On Linux and all Unix-like operating systems, the utilities ifconfig and the newer ip from the iproute2 -bundle are used to configure IEEE Please consult their man page to learn about their operation. In any case, these utilities configure the kernel directly and the configuration is applied immediately. After boot-up, the user is required to configure them again.

To apply the same static configuration after each boot-up, the PID1-programs are used: System V init executes shell scripts and binary programs, systemd parses its own conf-files and executes programs. In case the configuration has to be changed, DHCP -protocol goes a long way to do so automatically, without the user even noticing.

However, dynamic configurations i. Bootp was an early protocol used for this, and to this day its descendant DHCP is still very common. In this case, the first option below, may be the best. Network Manager has a command line tool that can be used to see which interfaces it is controlling. Pull up a terminal window and type the following command:. Any other value indicates the interface is under Network Manager control.

Network Manager settings are controlled by a configuration file: We will use this file to tell Network Manager to stop controlling a particular interface. List the MAC address of each interface you want Network Manager to ignore, separated with a semicolon. This syntax replaces the [keyfile] section above with the following:.
