Question.

- I use Debian 13 Linux.
- mDNS is an absolutely critical part of several things I do.
- Say on this network I have a Windows machine named "desktop" and a Linux machine named "laptop".
- On Linux, I type "ping desktop.local". Success. I "ping laptop.local". Failure. I "ping laptop". Success.
- Two months ago I am certain laptop.local resolved on the laptop.
- I *think* my mdns is provided by avahi, or at least apt-cache policy says avahi-daemon is installed.

How do I proceed?
