netplan config is ignored, who reconfigures my network? |

Trending 3 months ago

I person a instrumentality pinch aggregate NIC, for nan liking of simplicity we telephone them

  • ext0: uses DHCP, goes to nan outside
  • int0 and int1: person fixed IP adresses, spell to immoderate backstage network, wherever location is besides a DHCP server running, which different machines should use.

I person only 1 netplan config record (/etc/netplan/01-netcfg.yaml), which reads:

network: renderer: networkd version: 2 ethernets: ext0: dhcp4: true int0: dhcp4: false dhcp6: false addresses: - 192.168.X.X/24 int1: dhcp4: false dhcp6: false addresses: - 192.168.X.X/24

I tin tally netplan use and everything useful fine. After immoderate time, nevertheless int0 and int1 get further IPs complete DHCP, though this is explicitly prohibited successful my netplan config. I would not really mind that, if not additionally astatine immoderate point, nan default way would beryllium transferred to 1 of nan soul web interfaces.

Why is this happening? Which work is interferring pinch my web config? This is connected a cleanable instal of ubuntu 22.04.
