Bind9 Master/Slave Install


I installed a new BIND server (master and slave) following these directions: https://help.ubuntu.com/community/BIND9ServerHowto

I have both server talking to each other fine in which the slave has started getting notifies and have loaded the serials for the zones from the master server.

Logs:
19-Aug-2009 12:18:22.610 zone rev.1.10.10.in-addr.arpa/IN: sending notifies (serial 2009081901)...
19-Aug-2009 12:18:22.612 zone rev.2.10.10.in-addr.arpa/IN: sending notifies (serial 2009081901)...
19-Aug-2009 12:18:22.613 zone rev.3.10.10.in-addr.arpa/IN: sending notifies (serial 2009081901)....


However doing further testing with an xpclient machine, I have assigned a static IP address pointing to dns with the new DNS master & slave servers.

By doing an NSLookup on the xpclient, I get this:
DNS request timed out.
timeout was 2 seconds.
*** Can't find server name for address 10.10.1.15: Timed out
*** Default servers are not available
Default Server: UnKnown
Address: 10.10.1.15
dmrcsdr.csaa.com
Server: UnKnown
Address: 10.10.1.15
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Request to UnKnown timed-out

Ping:
Ping request could not find host dmrcsdr.csaa.com. Please check the name and try again.

Please advise on how to possibly resolve this.

You need the equiv of /etc/resolv.conf on XP; I've no idea what its called or where it is on MS, but you use it to tell the computer where the DNS server is.

Hmm that's weird that I have to input that in the host file in each client machine?

Can it be done automatically?

So what happens if I place these new DNS servers in production? Will I have to modify each client machines' host file in our network to enable them to resolve names?

Please advise.

Thanks.

Ok, I tried your suggestion just for the heck of it but did not resolve the issue.

Still getting error when doing nslookup:
********Cant find servername for address 10.10.1.15: Non-existent domain
********Default servers are not availble
Default server: Unknown
Address: 10.10.1.15
>

Any ideas?

Let's start with ping;

1. ping by ip address; can client see server?
2. ping by name ... same qn...
3. check firewalls on client and server
4. check tcp Wrappers on servers
5. check logs on client & servers

Answers:
1. yes
2. no
3. yes - permitted on client but on server, not sure they both run ubuntu.
4. no idea what this is
5. saw in the master dns' logs: network unreachable ns2.csaa.com
but weird thing is I am able to ping that server fine.

Can you help please?

Cheers mate!
