Q: DNS debian SERVFAIL server can't find, no ping I'm trying create a DNS server in my environment of test, but i don't know bind. The settings from my server is created with result of search in google. The bind start without error, but don't resolve my domain. I'm trying create a domain: lunarinterativa.labs to use in my solutions.
i receive this error:
server can't find www.lunarinterativa.labs.lunarinterativa.labs: SERVFAIL

when i execute the command below: 
nslookup
> server interativa32
Default server: interativa32
Address: 172.224.116.100#53
> www.lunarinterativa.labs
Server:         interativa32
Address:        172.224.116.100#53

My internal netwotk settings is:
ip address: 172.224.116.100
netmask: 255.255.255.0
gateway: 172.224.116.254

I ping to interativa32.lunarinterativa.labs: is OK

Now the ping is ok.
To me understand the problem i used the script from Wiliam Oliveira available in http://www.vivaolinux.com.br/script/Configuracao-Apache-e-DNS-(bind)
one special thanks to he. Your scripts not have error in my enviroment.
