Folks,
I have 3 Linux systems, one running F31 and 2 running F34. On one of
the F34 systems I have a local DNS server running. This has worked fine
in the past, but now I'm seeing strangeness on the 2 F34 systems.
I added a host to the DNS server for normal lookup and reverse lookup.
On the F31 system both:
host centos8-opstcore-vm.homenet172-16-96.com
and
host 172.16.96.20
work. The first returns 172.16.96.20 and the second returns
centos8-opstcore-vm.homenet172-16-96.com.
On the F34 which is the DNS server the first works, but the second fails
with:
Host 20.96.16.172.in-addr.arpa. not found: 3(NXDOMAIN)
On the other F34 system I get:
host 172.16.96.20
;; connection timed out; no servers could be reached
The interface has the DNS server pointing to the correct system. If I run:
nslookup
> server 192.168.10.66
Default server: 192.168.10.66
Address: 192.168.10.66#53
> 172.16.96.20
20.96.16.172.in-addr.arpa name =
centos8-opstcore-vm.homenet172-16-96.com.
>
Then it works.
What do I need to do on F34 systems to get DNS lookups working?
Any help is appreciated.
Paolo
