Disable DHCP in cockpit

[cooka90]

Hi all,

We are running Cockpit on Raspbian 10 Buster which works really well. However, we have a small problem (nothing major) when we give our raspberry pi a static IP, it still shows DHCP enabled in cockpit with two ip address assigned - one address is our static and the other is from dhcp. Are we able to disable dhcp in cockpit?

Thanks

Edit: had a look through the discussion thread, couldn't see anything similar to this problem. Apologies if there is!

You can enable/disable DHCP in the IPv4 and/or IPv6 settings of the interface (the "edit" link):

Does that work for you?

Hi Martin, thanks for your reply. Yes that does work, however I wondered if it would be possible to have it set to manual by default and not automatic. Again its not a massive burden, but if we ever reimaged the pi we would just need to remember to set this back to manual again.

This default isn't something that cockpit controls -- that's NetworkManager. Cockpit merely shows the current state.

When building pre-configured images, you shouldn't use Cockpit (as that's an interactive human tool), but something like preseed, cloud-init, Ansible, etc. Either call nmcli or ship a /etc/NetworkManager/conf.d/ snippet to set up that interface.

... or /etc/NetworkManager/system-connections/ file rather, which seems more appropriate for configuring a concrete ethernet interface.

Many thanks. Will take a look!
