Hi again list,

As I mentioned here before, I went from a partially-upgraded testing (a progress from KDE 5 to 6) to a newly-installed one. One thing I had a
problem restoring is the auto-detected network printer.

Now, those of you who read https://wiki.debian.org/Plasma%206 carefully
might already guess what the problem was, and you'd be mostly correct:
The main issue was that network printer autodetection depends on mdns
which is, well, a network service, and the newly installed firewall
blocks those.

So I figured it out, added a rule for mdns, and sailed on.

But it made me think: I am a relatively sophisticated user. The whole
point of mdns is for things to work "out of the box". The rules I had
on by default were to allow incoming ssh and dhcpv6 (not sure if it's
because I picked the "SSH Server" component in installation). Shouldn't
we allow mdns in by default?

Thanks for your attention,
Shai.

I think this makes sense.

Would you share your mdns rule ?
Do you know by any chance how to ship packaged firewalld rules ?
