named[4113]: error (unexpected RCODE REFUSED) resolving './DNSKEY/IN'
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 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 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: 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.
(42)
^… One of your clients sends a request to your DNS server asking for the
reverse-IP request (a “PTR” request) for the domain-name corresponding
to IP address 112.33.1.75 (expressed in reverse as
“75.1.33.112.in-addr.arpa.”)
Quiere decir que es el forwarder tuyo el del bateo.. que te refuse la
connection... viste ?? que te dije ?? o firewall por el medio.. o es que
tienen los dns alla arriba de ti cerrados y solo determinados ip pueden
consultar, posiblemente en la misma zona declarados los tengan sus
subdominios y a ti no te hayan declarado todavia. Podria ser ?
