Remove NIC's from DHCP

JustSomeGeek · 2019-01-15 11:52:08

Hi folks,

I have 3 NIC's:

en01 The onboard one
enp3s0f0 Port 1 of a dual NIC card
enp3s0f1 Port 2 " "

I want to remove both ports of the dual card from any DHCP or boot checks, as I only use them for VM's, and they are slowing down the boot process when they aren't connected to the network.

This is my systemctl list:

autovt@.service enabled
dbus-org.freedesktop.network1.service enabled
dbus-org.freedesktop.timesync1.service enabled
devolonetsvc.service enabled
getty@.service enabled
libvirtd.service enabled
netctl@enp0s31f6.service enabled
systemd-networkd-wait-online.service enabled
systemd-networkd.service enabled
systemd-timesyncd.service enabled
sshd.socket enabled
systemd-networkd.socket enabled
virtlockd.socket enabled
virtlogd.socket enabled
remote-fs.target enabled

Are any of these duplicating something else, or not needed?

What's the best way of skipping the NIC's from being evaluated?

Thanks! :-)

Please use [ code ] tags when pasting outputs.

You have multiple networking services enabled which is in and of itself already problematic, decide for systemd-networkd or netctl, don't use both at the same time. The interface netctl is hooked on doesn't look like any of the ones you mentioned, so might as well be contributing. Anything else depends on how and what you've configured, so you might share some configs here, and fwiw to make an informed suggestion, post the complete output of

sudo journalctl -b

after reproduction of the issue.

Thanks, i've removed netctl for starters. Seems to be due to conflicting tutorials I followed a few months ago.

If these were on our wiki, please point them out so they can be fixed. If they weren't, perhaps now you'll see why third party guides are ill-advised and unsupported.

It seems to have been the mention of several Network Managers at the stage where I was still trying to get Arch to "just work". I've probably installed networkd or netctl while trying to sort something, then picked up again later and tried something else without remembering. There often seems to be way more info than needed for someone just trying to get up and running, and often a Google for a different way of explaining things, with less info, can be exactly what's needed.
