Dafuck? Removed for rule 3? [email protected] what the?

As far as I’m aware running and getting DNS to work on a home network is precisely everything to do with self-hosting.

I get that I’m being a bit of an opinionated asshole, and maybe my post is not overly constructive, but shit, a good rant to start a discussion should not be a reason for removal, least of all for a rule that has blatantly not been violated and that’s the only actual reason I can think of why I’d been banned.

A good rant is literally the most worthwhile content imho, a good hearty debate invites viewpoints and opinions, even if the OP is unpopular. I hate the sterile, overly polite, overly PC tone enforced on some Lemmy communities.

As long as no one is literally insulting other users or spreading misinformation or being discriminatory/xenophobic based on characteristics. I wasn’t even swearing. I’m so done, I’m blocking all of lemmy.world until they get their shit together.

    The Pi is definitely running Avahi and spamming multicast, when it attempts to resolve .local, it sends out multicast and unicast simultaneously, even with freshly flushed DNS cache.

    I owe you an apology - I see now that my avahi systems are in fact also sending unicast SOA? local. when I resolve a .local name, and presumably if my recursor told them it was responsible for it instead of NXDomain then I would resolve names through it.

    I was pretty sure that it doesn’t do that, but before telling you that it doesn’t I actually did a test and ran tcpdump -ni any port 53 or port 5353 while resolving some .local names. i even noticed that there was that SOA query being sent to and from localhost (to systemd-resolved) but I saw no answer to it and figured that systemd-resolved was the thing silently ignoring that TLD. But: it turns out that the system I tested on has its systemd-resolved configured for DNSOverTLS so I wasn’t seeing those SOA queries being sent on to the recursor on a different port 🤦

    Sorry!

    It does seem to me like a regrettable choice of the RFC authors to allow both, though, as it is easy to accidentally have a situation where the recursor and mDNS return different answers which would lead to inconsistent results when querying both in parallel.
