Fix Wired Network interface in Kali linux

Kali Linux which is based on Debian Network Manager does not manage any interface defined in

/etc/network/interfaces

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:

[main]

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

 All Done!
