Hi!
I’m using unbound DNS resolver in a ubuntu container for my LAN requests. I’ve noticed, that ubuntu:latest is no longer work. The last image which is working ubuntu:bionic.
The issue is, that the unbound service is not able to handle upstream requests, returns with
** server can’t find index.hu: SERVFAIL
The local requests are still working:
nslookup socialtrade.biz dns-server
[ output omitted ]
Name: socialtrade.biz # this is an advertising site
Address: 0.0.0.0
Interesting: With debian:latest it does provide the same issue.
Here you can find the Dockerfile, configs, and the command with which I’m running:
https://github.com/kzl86/dns_server
I’m looking for a solution why this stopped working.
Thank you
