How To Start / Stop / Restart / Enable / Reload The Network Service In Linux?

systemd is a new system and service manager for Linux system, which was implemented/adapted into all the major Linux distributions over the traditional SysV init systems due to lots of issue/improvement has to be on SysVinit systems.

All the service files are available on /etc/init.d/ directory for SysVinit system.

For systemd system, the service files are available on /usr/lib/systemd/system/ directory.

If you would like to perform any kind of actions like start, stop, restart, enable, reload & status against the specific service then use the following commands.

Make sure that you should have admin privileges to run these commands except status command. It should be root or sudo permission needed to run the below commands.

What Is Network Manager?

NetworkManager is a dynamic network control and configuration system that attempts to keep network devices and connections up and active when they are available.

NetworkManager can be used to configure the following types of connections: Ethernet, wireless, mobile broadband (such as cellular 3G), and DSL and PPPoE (Point-to-Point over Ethernet).

# service network status or # service NetworkManager status or # /etc/init.d/network status

For systemd Systems – RHEL based systems such as Redhat, CentOS and Fedora.

# systemctl status network or # systemctl status NetworkManager or # systemctl status network.service

For systemd Systems – Debian based systems such as Debian and Ubuntu.

# systemctl status networking or # systemctl status networking.service

6) How To Enable The Network Service On Boot In Linux?

Use the below commands to enable the networking server on boot in Linux.

For SysVinit Systems – RHEL based systems such as Redhat, CentOS and Fedora.

# chkconfig network on or # chkconfig NetworkManager on

For systemd Systems – RHEL based systems such as Redhat, CentOS and Fedora.

# systemctl enable network or # systemctl enable NetworkManager or # systemctl enable network.service

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.

$ /etc/init.d/networking status

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.

$ sudo /etc/init.d/networking stop

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.

$ sudo systemctl stop network

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.

$ sudo /etc/init.d/networking start

Fedora,CentOS

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

$ sudo systemctl start network

Restart Network

Now we can restart our network or network services.

Ubuntu, Debian, Kali

$ /etc/init.d/networking restart

Fedora,CentOS

$ systemctl restart network

Kali Linux Network Manager Is Not Running: How to Fix It

If you are a Kali Linux user and have ever encountered the error message “Network Manager is not running” when attempting to connect to a network, then you know how frustrating this issue can be. In this article, we will discuss what causes this error and how to fix it.

Understanding the Issue

The Network Manager is a program that manages network connections on a Linux system. It is responsible for detecting and configuring network interfaces, managing wireless networks, and connecting to the internet. When the Network Manager is not running, you cannot connect to any networks, wired or wireless.

Common Causes of the Problem

Several factors can cause the Network Manager to stop running. Some of the most common causes include:

1. Outdated Network Manager: If you are using an older version of Kali Linux, it may have an outdated Network Manager that is no longer supported.
2. Conflicting Network Services: If there are other network services running on your system, such as dhclient or wpa_supplicant, they may conflict with the Network Manager.
3. Corrupted Packages: Sometimes, packages that are required for the Network Manager to function properly can become corrupted, leading to the error message.

How to Fix the Issue?

Now that you know what causes the problem, let’s look at how to fix it.

Method 1: Restart the Network Manager Service

The first thing you should try is to restart the Network Manager service. To do this, open a terminal and type the following command:

sudo systemctl restart NetworkManager.service

This command will restart the Network Manager service and should fix the issue if it was caused by a temporary glitch.

Method 2: Check for Conflicting Services

If restarting the Network Manager service did not work, you should check if there are any conflicting network services running on your system. To do this, open a terminal and type the following command:

sudo systemctl list-units --type=service | grep network

This command will show you a list of network-related services running on your system. If you see any services other than “NetworkManager.service,” you should stop them by typing the following command:

Replace with the name of the service, you want to stop. Once you have stopped all conflicting services, restart the Network Manager service using the command from Method 1.

Method 3: Reinstall the Network Manager

If neither of the above methods works, you may need to reinstall the Network Manager. To do this, open a terminal and type the following command:

sudo apt-get install --reinstall network-manager

This command will reinstall the Network Manager and any packages that it depends on.

Conclusion

In this article, we have discussed the “Network Manager is not running” error on Kali Linux and how to fix it. By following the methods outlined above, you should be able to resolve the issue and connect to your desired network. Remember to always keep your system up-to-date and to use caution when modifying system files.

Fix Wired Network interface in Kali linux

Unmanaged devices means Network Manager doesn’t handle those network devices.

So this is what you see in GUI

An roor@alexandria# ifconfig -a show you this:

This occurs when two conditions are met:

The file roor@alexandria# /etc/network/interfaces contains anything about the interface, even:

allow-hotplug eth0 iface eth0 inet dhcp

And roor@alexandria# /etc/NetworkManager/NetworkManager.conf contains:

plugins=ifupdown,keyfile [ifupdown] managed=false

Enabling Interface Management

If you want Network Manager to handle interfaces that are enabled in

roor@alexandria# /etc/network/interfaces

Set managed=true in /etc/NetworkManager/NetworkManager.conf . So this file looks like:

[main] plugins=ifupdown,keyfile [ifupdown] managed=true

Restart Network Manager

Issue the following command to restart network-manager.

roor@alexandria# service network-manager restart

Now Network Manager should come up with a connected interface. For wired, eth0 with DHCP will show you something like the following image:

Just to wrap it up, lets do another roor@alexandria# ifconifg -a from command line
