Hello list, I was wondering if anybody could advise please, on the line below that I always seem to get in my Bind 9.8.4 logs:
error (unexpected RCODE SERVFAIL) resolving 'dul.dnsbl.sorbs.net/A/IN':174.36.198.232#53 I know what it generally stands for, that is the name server was unable to process this query due to a problem with the name server (according to RFC 1035, 4.1.1). I am using ACL and I white-listed 174.36.198.232. I also white-listed and made sure the IP in question is not blocked anywhere else, like iptables and so on. However. I also notice that dul.dnsbl.sorbs.net has no A records so I think that this may not be the issue. Plus, I also noticed later that IP addresses changed regularly (it can be just about any other IP instead of where 174.36.198.232 is) so my white-listing was useless. I would be really thankful if anybody could assist on the correct setting to allow my named (Bind) server to communicate with dul.dnsbl.sorbs.net as all the other DNSBLs etc. I use on my server work and resolve well. I would appreciate any comments / pointers / help at all. Many thanks in advance! Regards, Dennis
