KDE - 'plasma-nm' problems

Hi there!

I decided to make a "bare bones" install of Debian Jessie. After that, I installed the "kde-full" package and rebooted into KDE. Problem is, no connection is shown on the NetworkManager applet. I thought this was a conflict between the "dhclient" and "NetworkManager" modules but clearly I was wrong.

I tried creating a new connection but it doesn't show up on the applet as well. However, I can create a VPN connection (I do need to use it) but I can't connect to it because NetworkManager complains about not finding the source connection.


Other useful info:

0 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
# dhclient eth0

Another thing is that I can't set iptables rules. One of the lines read as follows (original line + result displayed on the terminal):
root@xxxx:~# iptables -A INPUT -i enp0s7   -s xxxx   -j In_RULE_0
iptables v1.4.21: host/network `xxxx' not found
Try `iptables -h' or 'iptables --help' for more information.

root@xxxx:~# systemctl status NetworkManager
● NetworkManager.service - Network Manager
   Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled)
   Active: active (running) since Wed 2015-07-15 16:22:14 UTC; 46min ago
 Main PID: 472 (NetworkManager)
   CGroup: /system.slice/NetworkManager.service
           └─472 /usr/sbin/NetworkManager --no-daemon
BTW, I saw the "--no-daemon" part on that last line above. I tried "systemctl start NetworkManager", "systemctl stop NetworkManager", and "systemctl restart NetworkManager". None have any effect on the icon (the one by my system clock).

Is the network interface (eth0) managed by NM?

As of Debian 6.0 "Squeeze", NetworkManager does not manage any interface defined in /etc/network/interfaces by default.

Unmanaged devices means NetworkManager doesn't handle those network devices.
