Our DNS is having a problem trying to resolve some domains, and I'm wondering if anybody saw anything like that. As the RFC 2181, section 10.3 said, a RR mustn't be an alias. So in my opinion ther is the problem why bind dosen't retrieve any information of this domain. dig @localhost ns mediabusiness.tv ; <<>> DiG 8.3 <<>> @localhost ns mediabusiness.tv ; (1 server found) ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 39733 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUERY SECTION: ;; mediabusiness.tv, type = NS, class = IN ;; Total query time: 1 msec ;; FROM: my.server. to SERVER: 127.0.0.1 ;; WHEN: Thu Mar 17 17:28:30 2005 ;; MSG SIZE sent: 34 rcvd: 34 Bind Debug Level 3 ------------------ req: nlookup(mediabusiness.tv) id 61851 type=15 class=1 req: found 'mediabusiness.tv' as 'mediabusiness.tv' (cname=0) wanted(0x9011420, IN MX) [IN NS] wanted(0x90113f0, IN MX) [IN NS] findns: 2 NS's added for 'mediabusiness' ns_forw() find_zone(mediabusiness.tv, 1) find_zone: unknown zone find_zone(tv, 1) find_zone: unknown zone find_zone(., 1) find_zone: existing zone 1 nslookup(nsp=0xbfbfdb38, qp=0x8693000, "mediabusiness.tv", d=0) nslookup: NS "NS1.SENIC.BIZ" c=1 t=2 (flags 0x2) < NS 'NS1.SENIC.BIZ' NS points to CNAME < BAD nslookup: NS "NS2.SENIC.BIZ" c=1 t=2 (flags 0x2) < DELEGATION ?

So, I confirmed that this RR was delegated as aliases. dig @67.18.31.242 NS1.SENIC.BIZ ; <<>> DiG 8.3 <<>> @67.18.31.242 NS1.SENIC.BIZ ; (1 server found) ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2178 ;; flags: qr aa rd; QUERY: 1, ANSWER: 8, AUTHORITY: 0, ADDITIONAL: 0 ;; QUERY SECTION: ;; NS1.SENIC.BIZ, type = A, class = IN ;; ANSWER SECTION: NS1.SENIC.BIZ. 4H IN CNAME NS1.SENIC.BIZ.

Well any coment about it will be apreciated. ------------------------------------------------- Lic.
