I have an up-to-date Kali Linux 2018.2 with open-vm-tools installed on an up-to-date VMware Workstation Pro 14.

It's working as expected, but there's a little bug that I'd like to fix, the NetworkManager question mark and lack of Ethernet configuration inside 'Settings → Network', as seen in the image below.


My network is fully working, I can ping LAN and WAN, can resolve IP's and hostnames etc. So, I don't know why I'm getting this behavior. My VMware network settings are as follows:

                                   vmware settings


The question mark is displayed because Network Manager isn’t managing your connection; presumably, ifupdown is: look at the contents of /etc/network/interfaces, if it has lines describing eth0 or enp0..., that’s the reason.

You can either ignore the question mark, or if you want Network Manager to manage your connection, run ifdown eth0 (replacing eth0 as appropriate), delete the corresponding entries in /etc/network/interfaces, and configure Network Manager.

See the networking chapter in the Debian Reference for details.

  • Actually, I found the "issue". I'm still using ifupdown, but now the NetworkManager plugin recognizes that I'm using it, see the solution here. – JChris Jul 28 '18 at 21:03

To continue using ifupdown, but display it correctly on Gnome GUI you need to edit /etc/NetworkManager/NetworkManager.conf and change managed=false to managed=true for the [ifupdown] section.

After that restart NetworkManager with systemctl restart NetworkManager.

    That doesn’t quite allow you to “continue using ifupdown”, it tells Network Manager to manage interfaces listed in /etc/network/interfaces. See man NetworkManager.conf for details. (So ifupdown will set the interfaces up following /etc/network/interfaces, and then Network Manager will take them over and set them up as it sees fit.) – Stephen Kitt Jul 28 '18 at 21:34
