Hi,
I'm having a DNS problem with unbound after upgrading to FreeBSD 12-0 production.
I'm using unbound_local as a caching DNS server. My
The problem I see is
To debug, I set things back,
I can ping remote servers just fine. e.g.
Using
However,
If I change resolve.conf to use google DNS and not the local caching server, everything works:
I'm new to unbound, so might have set it up incorrectly. Here are what I think are the relevant files. Things worked until I upgraded from FreeBSD 11.2 Release to 12.0 Release.
Does anyone have an idea what's wrong?
I'm having a DNS problem with unbound after upgrading to FreeBSD 12-0 production.
I'm using unbound_local as a caching DNS server. My
resolve.conf file:
Bash:
# cat /etc/resolv.conf
domain example.org
nameserver 127.0.0.1
nameserver ::1
options edns0The problem I see is
jabberd2 (installed via pkg install) can't resolve DNS names when connecting to other jabber servers. Initially I thought jabberd2 had the problem. I worked around the problem by putting each of the remote servers IP address in /etc/hosts works around the issue.To debug, I set things back,
/etc/hosts no longer has the remote servers. I verified that the problem again exists.I can ping remote servers just fine. e.g.
ping jabber.org works.
Bash:
# ping -c 2 jabber.org
