Dns Recursion Error

Post by nicola.piazzi » 19 Apr 2016 06:42

I have "4) DNS Recursion : ENABLED"
It is better because it solves rbl problems that ban common dns ip
but Yesterday without doing nothing it stopped to work
making a ping of any host it doesnt solve, so mail service enter in error state
I solved setting 8.8.8.8 in dns
This morning I turned Recursion ON and now it work well

I am unable to know why happened and now I am afraid, do you know why happened ?

Did unbound stop running for some reason, by chance?

I am also seeing this even though recursion is enabled.
host -tTXT 2.0.0.127.multi.uribl.com
2.0.0.127.multi.uribl.com descriptive text "127.0.0.1 -> Query Refused. See http://uribl.com/refused.shtml for more information [Your DNS IP: 74.125.76.1]"
host -tTXT 1.0.0.127.multi.uribl.com
1.0.0.127.multi.uribl.com descriptive text "127.0.0.1 -> Query Refused. See http://uribl.com/refused.shtml for more information [Your DNS IP: 173.194.90.7]"
host -tTXT 3.0.0.127.multi.uribl.com
3.0.0.127.multi.uribl.com descriptive text "127.0.0.1 -> Query Refused. See http://uribl.com/refused.shtml for more information [Your DNS IP: 74.125.76.5]"

My local (different box, same network) DNS server (which my EFA box was pointing to before I enabled recursion) points to 8.8.8.8 (if that makes a difference).
If I run "service unbound status" it says that it is running and if I restart it, it stops and restarts without any errors.
I am running the latest version of EFA (3.0.1.1?).

Any ideas?

Thanks

You aren't recursing if you are forwarding to 8.8.8.8

It shouldn't be (no DNS server listed when I go to the IP Settings page and DNS Recursion is listed as enabled) but when I run nslookup, it is going through my local DNS server.
What do I need to force it to use recursive DNS and stop using the local DNS server?

Digging, it looks like the nameserver was being stored in /etc/resolv.conf
I deleted it from there, then toggled recursion off/on and that seems to have fixed it.
