Stopping dhcp from running if no connection found [Solved]

Mr Green · 2017-11-04 11:37:52

Have a weird issue with Network Manager. On booting my desktop systemd is looking for dhcpd

dhcpcd@enp3s0.service                                                                                 loaded failed failed    dhcpcd on enp3s0

Then it hangs for 1 minute 30s while it is connecting, trying to disable but it returns on next boot.

I use wireless so there is no need to look for connection.

Do not have the problem on my laptop...

Not sure if it is a runlevel problem?

No, because there are no runlevels in systemd

You should not have both running, see wiki https://wiki.archlinux.org/index.php/Ne … HCP_client

Yes and no, maybe I misunderstood

If I disable dhcp service it simply returns on next boot

Hm, maybe you have NM using dhcpcd as a DHCP client from a long time ago? Post your /etc/NetworkManager/NetworkManager.conf

systemctl list-unit-files --state=enabled

disable the service and run the above again. reboot and run int once more. post all three outputs.

Does not make any difference

# Configuration file for NetworkManager.
# See "man 5 NetworkManager.conf" for details.

It's not enabeld to begin with. Either networkmanager generates and invokes it on the fly or sth. entirely different tries to start it.

Mr Green · 2017-11-05 08:52:53

Have renamed service to 'munch' and now system boots as it should. You are more than likely right that Network Manager is trying to start a wired connection. As I have said it does not happen on my laptop so no idea why it should be any different.

Anyway thanks for your help, marking as Solved
