How To Start, Stop, Restart Networking On Linux?

I have changed my network configuration and want to restart to make changes effective. Or there are some problems with my network and I think restarting it will solve my problems. Here we will look at how to restart networking service in various network distributions like Ubuntu, Debian, Fedora, CentOS.

Get Status Of Network Service

We will get status of network with the following command.

Debian, Ubuntu, Kali

For deb based distributions we will use init.d system. We will provide status option to the networking script.

As we cab see that networking service is active from given date. Its PID is 897 .

Fedora, CentOS

For distributions like CentOS, RedHat, Fedora we will use systemctl command. We will provide the options status and network which is the networking service.

Stop Network Service

We can stop network like below. Bu keep in mind for remote connection it can be create problems with ssh

Ubuntu, Debian, Kali

We will use stop option with networking command in order to stop network services in Ubuntu, Debian, Kali, Mint etc.

Fedora,CentOS

We will use systemctl again with stop option which will stop network services. We also require root privileges that will beget with sudo command.

Start Network

We can start network like below.

Ubuntu, Debian, Kali

We will provide start option in order to start network services in deb based distributions.

Fedora,CentOS

We will use start network option in order to start network services in rpm based distributions.

Restart Network

Now we can restart our network or network services.

How to Restart Network on Linux Mint

In this post you can find how to restart the network on Linux Mint. Network restart is needed in many situations like:

• change in network settings
• slow connection
• frequent disconnects

There are many ways in which you can restart the network on Linux Mint. Let’s check the most popular ones using the UI and the terminal.

For sound and video problems you can check:

Option 1: Restart network from GUI Cinnamon

The first option to use is the Cinnamon user interface. It allows you to restart all connections: Wi-Fi or wired.

• Main menu
• Preferences
• Network (Cinnamon-settings)
• Select the network which should be restarted
• Turn it off
• Turn it on

This should restart the network and fix problems if any.

Option 2: Restart network from network applet

The network can be easily stopped and started from the network applet. It is shown in the left side of the panel where the notifications are.

After clicking on the applet you will see all connections. To turn off and on a connection just click the button as shown on the image:

Option 3: Restart the network manager service

If you like to use the Linux Mint terminal to restart the network then you can try with restart the network . Use the next line:

Root password will be required. Then you will get a notification that the connection has been disconnected.

Option 4: Restart the network by nmcli tool

A tool called nmcli can be used to stop and start the Linux Mint network. This can be done in the terminal with next two commands:

Перезапуск сети в Ubuntu

В Ubuntu и Debian инициализацией сетевых интерфейсов и настройкой сети занимается специальная сетевая служба — networking. Информация о конфигурации сетевых интерфейсов хранится в файле /etc/network/interfaces.

Если вы что-либо измените в этом файле, нужно будет перезапустить сеть, чтобы применить изменения. В этой статье мы рассмотрим как выполнить перезапуск сети Ubuntu 16.04.

Перезагрузка сети в Ubuntu

Можно, конечно, выполнить полную перезагрузку компьютера, но это не совсем удобно если можно просто перезапустить сеть Ubuntu. Для перезапуска сети используйте следующую команду:

sudo service networking restart

В современных дистрибутивах уже давным давно используется система инициализации Systemd, поэтому можно использовать команду systemctl вместо команды service:

sudo systemctl restart networking.service

Кроме того, можно перезапустить NetworkManager, это тоже помогает, если сеть настроена через него:

sudo systemctl restart NetworkManager

Перезапуск сети в NetworkManager

Чаще всего, для управления сетью в современных дистрибутивах используется программа Network Manager. Можно сразу же использовать ещё для наших целей. Просто отключите, а затем включите сеть обратно следующими командами:

sudo nmcli networking off

sudo nmcli networking on

После отключения сети значок NetworkManager пропадёт с панели, а потом снова появится после включения. Аналогично, вы можете использовать NetworkManager в графическом интерфейсе. Кликните по его иконке, выберите нужное сетевое подключение и нажмите Выключить:

Затем включите его обратно.

Команды ifup и ifdown

Эти команды работают на более низком уровне, они управляют непосредственно самими сетевым интерфейсами. Для перезапуска сети мы можем отключить все интерфейсы, а затем включить обратно:

Вы не увидите никаких изменений в графическом интерфейсе, но когда сетевой интерфейс будет отключён, вы не будете иметь доступа к интернету.

Выводы

Как видите, не всегда обязательно перезагружать компьютер после изменений настроек, в большинстве случаев достаточно перезапустить только нужный сервис. Надеюсь, эта информация была вам полезной.

How to restart network services in Linux

Sometimes, when you changed the network configuration or due to some network problems, you may need to restart the network services again on your Linux system to solve your problem. In this article, we will talk about how to restart the networking services on in different Linux distributions (Ubuntu, Debian, LinuxMint and CentOS) by using the command line. We have implemented different commands on Ubuntu 20.04 and CentOS 8 system. All commands which we have executed on Ubuntu 20.04 can be also used for Debian and LinuxMint distributions.

Get network Service Status

You can get the network services running status by using the following command:

For latest (Ubuntu/Debian/Mint)

To check the networking services are running on your system or not, by using the following ‘systemctl’ command you can view the networking service status on your Ubuntu/Debian/Mint system:

You can also display the networking service status by using the service command which is given as follows:

For CentOS 8 / Fedora

If you are using CentOS 8 then you can check the network service status by using the following command:

If you received an error like ‘network.service unit not found’ then, you will run the following command to start the network manager:

Now, start the network services and you can get network status by using the above-mentioned command.

Stop Network Services

You can stop your network services through the method which is mentioned below. But, if you have a remote connection with SSH, we are not recommended you to stop the service because it may create problems.

For Ubuntu/Debian/Mint

You can use the ‘stop’ option with the above ‘networking’ command on Ubuntu, Debian, Kali, Mint distributions in order to stop network services.

For CentOS 8/Fedora

In CentOS 8, using the following command you can stop network services:

Now, if you will check the network status you will see that network services are stopped on your system.

Start Network Service

If networking services are stopped on your system then, you start these services on the Linux system.

Restarting, Starting, Stopping, Checking the Status of the Network Service in Linux

In Linux-based operating systems, information about network operations such as network settings, network commands or network configuration is included. In Linux operating systems, as everything is a file, network settings are also kept in files. The settings can be edited with any text editor or by various tools.

Network settings are located in the following files and directories.

Each of the settings files is used for different operations. The files in the network-scripts directory are used for network settings. Network settings are eth0, eth1, etc. according to the network card in files starting with ifcfg. kept by names.

Inside the network settings;

It also has various settings such as MAC address, Network type. When you want to get IP using DHCP , it will be sufficient to write the DEVICE, BOOTPROTO and ONBOOT settings.
