I’m pulling my hair out over this. I’ve got a proxmox homelab, an LXC running technitium installed from TTeck’s script.
The DNS server is also doing DHCP for my network. I have an authoritative zone for ‘.lan’
I can get NS, SOA, TXT records from the DNS server, but no A records! The DNS query logs show that it gives an answer, and if I am on the DNS server itself I get an answer, but no other machines on the network hear the reply.
I think this means the DNS server is working properly. There are no FWs in the way as I can resolve other types.
Where else can I look, or how can I diagnose this? I am completely at a loss.
Well, dig is available also of course, but nearly all distros still include nslookup despite it getting deprecated. I like the simplicity of its interactive mode.
Host is also really great with more human-readable output.
Don’t get me wrong, when things are getting hairy, you’re going to make a lot of use of dig. I just find that most troubleshooting can be taken care of a lot simpler with host or nslookup.
