Error Unexpected Rcode Servfail Resolving Named
Contents |
Bind logs? named[xxxxxx]: unexpected RCODE (REFUSED) resolving ‘xx.xx.xx.xx.in-addr.arpa/PTR/IN': xxx.xxx.xxx.xxx#53 This is probably because you have a forwarder in your named.conf that refuse your requests. Simply look at the end of the previous line : "xxx.xxx.xxx.xxx#53" error (formerr) resolving and search this address in your named configuration file - it should be lame server resolving located inside the forwarders : Shell forwarders { xxx.xxx.xxx.xxx; }; 1 forwarders { xxx.xxx.xxx.xxx; }; You need to remove rcode refused dns or comment this host to get rid of the error in log or allow your host to query this server if it belongs to you! Tip : To make sure the

remote DNS server you are trying to query is refusing your request, you can try to DIG a host like this replacing the domain and IP to meet your situation : Shell dig domain.tld @xxx.xxx.xxx.xxx 1 dig domain.tld @xxx.xxx.xxx.xxx Be Sociable, Share!

"error (unexpected RCODE REFUSED)" mean? Posted by Eric on 14 July 2015, 1:29 am If you're seeing this in the /var/log/syslog on your BIND DNS server: Jul 14 00:56:13 kla-dns-01 named[8255]: error (unexpected RCODE error (network unreachable) resolving REFUSED) resolving '75.1.33.112.in-addr.arpa/PTR/IN': 211.136.17.105#53 ..it means that a client has asked your

server to look up a domain name that your server didn't know about, and when it forwarded the
Named Allow-query
request to it's forwarders, the remote DNS server refused to respond. A packet trace on your DNS server shows exactly what's happening: root@dns1:/# tcpdump -n -s 1514 -v 'port 53' tcpdump: http://www.itechlounge.net/2011/12/bind-unexpected-rcode-refused-resolving-xx-xx-xx-xx-in-addr-arpaptrin/ listening on eth0, link-type EN10MB (Ethernet), capture size 1514 bytes 00:56:09.686771 IP (tos 0x0, ttl 62, id 44942, offset 0, flags [DF], proto UDP (17), length 70) 10.5.11.101.42237 > 10.0.10.10.53: 17985+ PTR? 75.1.33.112.in-addr.arpa.

The nameserver responded with a SERVFAIL error code. The nameserver responded with a REFUSED error code. The client was denied access to read the cached response for that domain. 1-3 are issues with the configuration of the nameserver for the domains/zones in question, #4 is caused by your local security configuration restricting the (probably remote, unauthorized) from reading from your local query cache.
