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. DB :confused: |
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.

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. DB |
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? DB |
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 |
Quote:
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! |
The client side nslookup:
DNS request timed out. timeout was 2 seconds. *** Can't find server name for address 10.10.1.15: Timed out *** Can't find server name for address 10.10.1.16: Query refused *** Default servers are not available Default Server: UnKnown Address: 10.10.1.15 > crossfader Server: UnKnown Address: 10.10.1.15 DNS request timed out. timeout was 2 seconds. *** Request to UnKnown timed-out > android Server: UnKnown Address: 10.10.1.15 DNS request timed out. timeout was 2 seconds. *** Request to UnKnown timed-out |
