问题描述:

My server is a Ubuntu, and I have installed webmin/virtualmin and I´m trying to create my NSRecord ns1 and ns2.

I run this command:

dig @localhost mydomain.info

; DiG 9.7.3 @localhost mydomain.info

; (1 server found)

;; global options: +cmd

;; Got answer:

;; HEADER opcode: QUERY, status: NOERROR, id: 64570

;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1

;; QUESTION SECTION:

;mydomain.info. IN A

;; ANSWER SECTION:

mydomain.info. 38400 IN A 10.28.166.120

;; AUTHORITY SECTION:

mydomain.info. 38400 IN NS ns1.mydomain.info.

;; ADDITIONAL SECTION:

ns1.mydomain.info. 38400 IN A 10.28.166.120

But 10.28.166.120 it´s my local IP, I try to find any information on /var/log/syslog about Bind and I didn´t see anything.

In Firewall I configured the ports like this:

Incoming open ports:

TCP/53

UDP/53

Outgoing open ports:

TCP/53

UDP/53

TCP/1024-65535

UDP/1024-65535

So, know I put my complete dns record:

$ttl 38400

@ IN SOA ns1.mydomain.info. root.ns1.mydomain.info. (

1342267814

10800

3600

604800

38400 )

@ IN NS ns1.mydomain.info.

mydomain.info. IN A 10.28.166.120

www.mydomain.info. IN A 10.28.166.120

ftp.mydomain.info. IN A 10.28.166.120

m.mydomain.info. IN A 10.28.166.120

ns1.mydomain.info. IN A 999.999.999.999

localhost.mydomain.info. IN A 127.0.0.1

webmail.mydomain.info. IN A 10.28.166.120

admin.mydomain.info. IN A 10.28.166.120

mydomain.info. IN TXT "v=spf1 a mx a:mydomain.info ip4:10.28.166.120 ?all"

999.999.999.999 = my external IP

I´m tried post some questions like this and anyone help on other forums. If anyone don´t undestand something I will try to explain.

Thank´s.

网友答案:

BIND runs as named, so that is what you should look for in the logs. (Though nothing is actually wrong with this setup, so I doubt there would be anything in the logs).

I'm not sure how you've set up the records in your zone, but each NS record points to an A record. The NS record looks fine, but the A record is wrong. The other NS record and/or its corresponding A record are missing. You will have to change the A record for ns1.mydomain.info. to your external address. There is no simple way to use both an internal and external IP for a single machine (for a complicated way, see split-horizon views).
