Raspberry Pi4B, Raspbian 10.10. Behavior I want: if ethernet is available use that, otherwise use wifi. Behavior I get: both are up, each with its own IP. How do I make it not bind wifi if eth is working?
Second: I would like the host to always have the same static IP, regardless of whether it chose ethernet or wifi. With a "real" DHCP server I was able to accomplish that like so:
host NAME-a { fixed-address NAME; hardware ethernet MAC-ETH0; }
host NAME-b { fixed-address NAME; hardware ethernet MAC-WIFI; }
But these days my DHCP server is a UniFi UDM Pro 1.11.4, and It seems to insist upon a 1:1 mapping between IPs and MACs. Is there any way to accomplish this eminently sensible thing?
As always, please note:
- These are two extremely specific questions.
- Your guesses are not helpful.
- Your opinion that I should not want this, likewise.
