DNS server - *** Can't find server name for address 127.0.0.1: Server

[richdthomas]

Hi,

I am trying to set up a pair of internal DNS servers (primary and secondary) on Sun Solaris 8.

I do not need these servers to resolve real outside world DNS names like

http://www.yahoo.com

I simply need to specify a list of internal private IP addresses and private DNS names.

E.G.

192.168.199.1 firewall_a.dmz.loc
192.168.199.10 firewall_b.dmz.loc

etc.

I have set up the files /etc/resolv.conf, /etc/nsswitch.conf, /etc/named.conf, /var/named/db.dmz.loc, /var/named/db.192.168.199, /var/named/db.127.0.0, I have showed the content of these files at the bottom of this posting.

I rebooted the server once I had set up these files.

I have an error which points to the fact that I have not set up the named.ca file.

I realise that the way in which it's set up is different for resolving private and public DNS names and IP addresses.

The configuration of this file refers to a route server, which I do not intend to use, as my DNS setup is fairly straightforward.

I then populated /var/named/named.ca, to see if it would make any different, but it still resulted in the same error.

The error I get is when I run "nslookup" to test the setup and is as follows:
*** Can't find server name for address 127.0.0.1: Server failed
*** Can't find server name for address 192.168.199.44: No response from server
*** Default servers are not available

I have read and followed the documents in the following web pages:

http://docs.sun.com/db/doc/806-1386/6jam5ahnb?q=DNS+server&a=view

http://www.networkclue.com/internet/DNS/bind/

http://www.zytrax.com/books/dns/ch7/options.html

I have also checked that the name demon is running, which it is:
ps -ef | grep named
root 169 1 0 Jun 22 ? 0:00 /usr/sbin/in.named

The IP listener is running as well:
# netstat -na | grep 53
127.0.0.1.53 Idle
192.168.199.42.53 Idle
127.0.0.1.53 *.* 0 0 24576 0 LISTEN
192.168.199.42.53 *.* 0 0 24576 0 LISTEN

If anybody has any suggestions, please could you let me know.

Thank you.

Richard Thomas.
