ndc – how to see lots of DNS informationWhen I was adding some new virtual domains, I had some trouble figuring out why only I could see the websites. One of the tools I used to solve this problem was ndc.
I issued two commands:
su-2.02# ndc dumpdb
su-2.02# ndc stats
I found the output in /var/tmp. The files created were named.stats and named_dump.db.
The information I was trying to obtain was the name server for the CX domain. I found this in the /var/tmp/named_dump.db file. Here’s what I was looking for:
CX 20179 IN NS NS0.PLANET-THREE.COM. ;Cr=addtnl [220.127.116.11] 20179 IN NS NS1.PLANET-THREE.COM. ;Cr=addtnl [18.104.22.168] 20179 IN NS NS2.PLANET-THREE.COM. ;Cr=addtnl [22.214.171.124] 20179 IN NS NS0.FLIRBLE.ORG. ;Cr=addtnl [126.96.36.199] 20179 IN NS NS.GBNET.NET. ;Cr=addtnl [188.8.131.52]
The above lists the name servers for the CX domain. These are the servers which are your first line of reference when a .cx domain is being resolved. In my case, I was looking for freebsddiary.cx. Here’s how I resolved that name using the above information.
Default Server: localhost
> server NS0.PLANET-THREE.COM
Default Server: NS0.PLANET-THREE.COM
*** NS0.PLANET-THREE.COM can't find freebsddiary.cx: Non-existent host/domain
This tells me that the name server knows nothing about my domain. Which probably means the DNS servers haven’t been updated yet. I’ve only just registered the domains. And .cx updates the servers twice daily.
