Why is it that I can find post after post with people trying to get local network name resolution working and failing? There are some very bright people here, and they can’t find a solution to it.
I have an integration that needs to connect to a server name, no matter what I do I cannot get it to connect reliably, it works for a random amount of time then stops. Removing and re-adding is very hit and miss. Lookups from the host work fine (it is a ready-rolled image hosted in Hyper-V), or any other network device.
It seems that there are some DNS IP addresses hard-coded somewhere - and cannot be removed - which just causes confusion. We should have proper control over this.
PLEASE for the sake of everyone’s sanity can we have something done about this?! DNS options/update does not work reliably.
Oh please yes! Using tcpdump I was able to determine that HA is bypassing my selected DNS server (AdGuard) and instead resolving via 18.104.22.168! This is despite the ha dns into command showing nothing of this server.
I have similar issues. Local DNS resolution only works for a certain time after restarting the local DNS server. I should ask my separate Adguard RPI instance under .222 which in turn is configured to resolve .fritz.box with the local FritzBox (.1).
The “only works for a certain time” had me thinking I was going mad and that I had network issues (the Pi I was trying to resolve is in another subnet in a DMZ…), it would work then break itself - not helpful behaviour!
Hmm… local is a worry.
I had an issue this week with sources.list on my Proxmox box timing out on FTP.au.debian.org that I had never had an issue with before yet it was actually up so I ended up just changing the mirror in sources.list and it updated normally. Honestly these stupid inexplicable errors just wear me out.
Weirdly I seem to be seeing the same with the latest docker image. I’ve verified /etc/resolv.conf has the correct servers by exec’ing bash in the container and can even get the nslookup command to resolve succesfully but HA itself will not. What am I missing here? I’d really prefer to not have to load up a VM just for HA
