I have admin’ed unix and linux systems since before hair was invented. However, I have just started using Ubuntu. My understanding is that the netplan file is used to configure systemd-networkd in a typical Ubuntu server (at least the 20.x versions).
I am not using MAIB’s built in name service. My DNS is hosted at Google and I have an internal DNSMasq cacher on another sever on my network.
- That server is listed first in my
resolv.conffile lists only the loopback and I can’t look up hosts on my local network with either
- I have tried running
netplan apply, but nothing changes.
What is the appropriate method of configuring and applying network changes on an MAIB server so the config will take and will not be overwritten later? Or, what can I safely change on an MAIB server?
