How to Start, Stop or Restart Network Services on Rocky Linux 8
You may need to restart or stop network services on your Rocky Linux system occasionally. This article shows you step-by-step how to start, stop, or restart network services on Rocky Linux 8. The same commands also work on other RHEL clones such as AlmaLinux 8 and CentOS 8.
Steps to start, stop and restart the network service
Open the terminal window on your system and run the ‘su’ command on the terminal to log in as the root user.
There are the following two ways through which you can start, stop or restart network service:
Now, we will explore each way one by one in the following tutorial:
Use of NetworkManager service
To start a network service on the RockyLinux 8, you will run the below-given command:
$sudo systemctl start NetworkManager.service
The above-mentioned command is used to start a network service on RockyLinux 8.
To stop a network service on the RockyLinux 8, you need to run the below-mentioned command:
$sudo systemctl stop NetworkManager.service
To restart a network service, you need to execute the following command:
$sudo systemctl restart NetworkManager.service
Use of nmcli tool
The nmcli is a tool or utility that is used for managing the NetworkManager services through the terminal.
Note: Before starting to use nmcli utility, it is noted that do not try to execute ‘$nmcli networking off’ for those systems that are connected remotely with others. This command will stop or disable the NetworkManager settings and you will disconnect from the network connection.
To turn on the network services, you will type the following command on the terminal in RockyLinux 8.
To stop or turn off the network services, you will execute the following command on the terminal.
$sudo nmcli networking off
Conclusion

Linux network services: How to start, stop, and check their status
A service (also called a daemon process) is software that runs on a computer, generally in the background. This is usually because it’s something that the administrator isn’t likely to interact with directly.
Training & certification
For instance, a network service runs at the application layer to provide some form of service over a network. It’s expected that client computers will contact the service for access. A common example is the Apache web server. It runs on a system so that devices connected to the internet can view a specific set of files on a computer.
Red Hat Enterprise Linux (RHEL) provides an environment where these network services can run. RHEL also provides a utility named systemd to help you manage these services.
systemd has been the default service manager since RHEL 7. It’s the first thing that gets started (PID 1), and it is responsible for starting the rest of the system. It activates server daemons, system resources, and various other processes. With systemd, you can start, stop, and check the status of the network services running on your server. You interact with systemd by using the systemctl command.
Start a service
To start a given service, use:
For example, to start the sshd service, type:
$ sudo systemctl start sshd.service
You can ignore .service and run the systemctl start sshd command.
List services
You can list all loaded services on a server with:
$ sudo systemctl list-units --type=service
Stop a service
To find out whether a service is running, inactive, enabled, disabled, or has exited, use:
$ sudo systemctl status sshd
The systemctl command also has is-active and is-enabled options to see whether a service is active or enabled. For example, to check if a service is active or enabled, run:
This command gives two possible outputs. The service is either active , which means it is running, or it’s inactive , which means it is stopped or not running.
Enable a service
You can configure a service to start automatically with the system so that you don’t have to start it manually after the server reboots or restarts.
To enable a service, which means the service starts automatically when the server boots, use:
$ sudo systemctl enable sshd
To both start and enable a service, add the —now option, like this:
$ sudo systemctl enable --now sshd
To check whether a service is enabled, enter:
$ sudo systemctl is-enabled sshd
When a service is enabled, it starts automatically at boot. When it’s disabled, it doesn’t start automatically at boot.
Disable a service
To disable a service, so the service will not start automatically at boot time, run:
$ sudo systemctl disable sshd
Wrap up
Not everything uses systemctl by default. Some applications are intended to be started manually. Of course, you can always add your own systemd service files when you need a network service to start automatically.
Systemd is full of features, and the systemctl command gives you easy control over the services your computer runs.
How To Start / Stop / Restart Network Service in OpenSUSE Linux
In this tutorial, I will take you through the steps to Start / Stop / Restart Network Service in OpenSUSE Linux. If you are performing some changes in network configuration file then you always need to stop/start/restart network service for changes to take effect. Similarly if you are troubleshooting any network issue then also you might need to restart network service few times. There are few commands available in OpenSUSE Linux which can be used to stop/start/restart network service in Linux. We will go through those commands and understand the usage with the help of examples.
How to Start / Stop / Restart Network Service in OpenSUSE Linux
1. How to Start Network Service in OpenSUSE Linux
If you want to start your network service in OpenSUSE Linux then you need to use service network start command as shown below. Alternatively you can also use systemctl start network command to start network service.
Please note that here I am using root user to run all the below commands. You can use any user with sudo access to run all these commands. For more information Please check Step by Step: How to Add User to Sudoers to provide sudo access to the User.
2. How to Stop Network Service in OpenSUSE Linux
If you want to stop network service then you need to use service network stop command as shown below. Alternatively you can also use systemctl stop network command to stop network service.
3. How to Check Status of Network Service in OpenSUSE Linux
If you want to check the status of Network Service then you need to use service network status command as shown below.
Alternatively you can also use systemctl network status command to check the status of network service.
