030 - How To Configure Network In Linux Using NetworkManager (nmcli & nmtui) | RHEL 8

In this video, we will take a look at different ways of setting up IP address in network devices. We will briefly see "ip" commands to view IP address, routing table and link state information and then we will jump into NetworkManager daemon and see how can we utilize it to setup IP address statically and DHCP method. We will use "nmcli" command to setup and modify IP address information and then we will also see "nmtui" command to setup network interface device using Text-User Interface.
If you are not comfortable using "nmcli", "Network Manager Command Line Interface" command, you can use more easy method, "nmtui", "Network Manager Text User Interface", which is accepted to use in RHCSA exam as well.

i still get 'unknown connection' error.. is it because I am using wifi? I made an interface with ethernet type tho

[@CommandLines]

You would have to make an interface with wireless (wlan0) type.

How to activate network if mine is wireless?
When using the ncmi con up. It says connection failed.

[@CommandLines]

Did it give you any error while creating the connection for the wireless device?

[@gondorianslayer4250]

@@CommandLines i think so. It said something error connection failed.

[@mathewt-yh4il]

How we can fix network manager is not running??

[@CommandLines]

If "systemctl start NetworkManager" doesn't start it, check if it is enabled during boot. If not, you can issue command "systemctl enable NetworkManager" and restart the computer. If that doesn't work, you might want to uninstall and install the service.
