I setup a DNS server today on Ubuntu, following this tutorial. My intent was to setup my network for dns-name resolving on the private LAN within a single zone (nothing fancy I just want name resolution).
I've tested the setup on the DNS server machine itself, and I can ping all the machines listed in the configuration file. I've also configured the Windows Machines on my network, and for some reason they are incapable of pinging by names as was possible on the DNS Server itself.
I've tried running nslookup on the Windows DNS clients and I receive and error mentioning the address of the DNS server.
DNS forwarding works fine, I'm not having any trouble accessing the internet, the problem only lies within accessing names within the private LAN.
Here are my configuration files:
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk. See http://www.kb.cert.org/vuls/id/800113
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.
// forwarders {
// 0.0.0.0;
// };
forwarders {
8.8.8.8;
8.8.8.4;
74.242.0.12;
//68.87.76.178;
};
auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};
/etc/bind/named.conf.options
zone "leerdomain.local" {
type master;
file "/etc/bind/zones/leerdomain.local.db";
notify no;
};
zone "2.168.192.in-addr.arpa" {
type master;
file "/etc/bind/zones/rev.2.168.192.in-addr.arpa";
notify no;
};
/etc/bind/named.conf.local

(Validates fine with named-checkzone when validating zone leerdomain.local)

*(Does not validate with named-checkzone when validating zone leerdomain.local gives an error of: zone leerdomain.local/IN: NS 'ns.leerdomain.local' has no address records (A or AAAA)
zone leerdomain.local/IN: not loaded due to errors. *
Despite not validating bind9 starts without errors in /var/log/syslog
I've also configured a few of the windows machines on my network to have the static ip as specified in the lookup and reverse lookup config files.
i.e.
Using nslookup yields the following results:
C:\Users\leeand00>nslookup ns
Server: UnKnown
Address: 192.168.2.9
*** UnKnown can't find ns: Non-existent domain
C:\Users\leeand00>nslookup gw
Server: UnKnown
Address: 192.168.2.9
Name: gw.
Additionally trying to ping by name also fails on machines that are not the DNS Server.
Is there something wrong with my configuration of either the nameserver or the Windows Boxes that is keeping me from accessing other machines using names?
