How to restart the network via command line

Restarting the network of your AlmaLinux system is useful for troubleshooting steps. For example like, if you’re having any problems connecting to the internet.

To turn the network completely off and back on in AlmaLinux, we can use the following NetworkManager commands.  This effectively restarts the network for the operating system.

# nmcli networking off
# nmcli networking on

We can even turn off and on back individual network interfaces. To see the currently configured interfaces, you can use the "ip a" command.

$ ip a
...
2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:14:b7:83 brd ff:ff:ff:ff:ff:ff
    inet 192.168.137.132/24 brd 192.168.137.255 scope global dynamic noprefixroute ens160
       valid_lft 1652sec preferred_lft 1652sec
    inet6 fe80::5f00:9be8:e9e7:afff/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

In this case, the interface we have to reset is "ens160". The below commands will take the interface down and put on back up, effectively restarting it.

# ifdown ens160
Connection 'ens160' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/5)

And then put it back up:

# ifup ens160
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)

One last way would be to reset a network interface in AlmaLinux with the ip link commands. This work through the networkd.

# sudo ip link set ens160 down
# sudo ip link set ens160 up

Use the below command to restart the server networking service.

# nmcli networking off
# nmcli networking on
or
# systemctl restart NetworkManager

Once done, use the below command to check the server network status.

# nmcli -o
or
# systemctl status NetworkManager

How to restart the network via GUI

If running the default GNOME GUI on AlmaLinux. Then the simplest way to restart the network is to click on the top right settings area of the taskbar. Next, select the network interface you wish to reset. Finally, click “Turn off.”

• Turn off the network connection.

• Next, click again to turn it back on.

• Turn the network connection back on.
