Bind dns resolving local servers

[darkod]

For each modification of the zone file you need to change the Serial value. Not sure if bind is insisting on that or not. I notice you have serial of 6 now and before, you didn't change it.

Best to use date format with couple of digits on the end (two digit XX would allow you up to 99 changes on the same day). Try putting the serial at 2018052501 and restart bind.

And the IN NS line is not correct, it needs dot at the end:

@   IN   NS   server001.linux-network.home.

Change that line and the serial, restart bind and try the nslookup again.

It depends. see this.

Good catch. I've been looking and looking and didn't see it.

I am now able to do a nslookup and dig and get results using the fqdn.

question, to add my other servers do I just create the two A records for each server?

@ IN A 192.168.1.110
server002 IN A 192.168.1.110
@ IN A 192.168.1.111
server003 IN A 192.168.1.111

No. Leave out the @ lines. Do this:

server002              IN      A         192.168.1.110
server003              IN      A         192.168.1.111

Thank you! I am now able to do a dig and nslookup from my ns server001 and get responses. I seem to be having issues from other devices getting the answers though. Have any suggestions on that one?

on server002 here is what I get.

here is my dig


Here is my nslookup

[Doug S]

well, you do not seem to have told server002 to use server001 as its DNS. How you do that depends on how server002 gets it IP address, and, I suppose, with 18.04 if you're using netplan or not. If you are using static IP addresses (and not netplan) you can specify in the /etc/network/interfaces file using the "dns-nameservers" stanza. If you are using DHCP and a DHCP server, then it can be specified with the lease response data using the "option domain-name-servers" stanza.

I use 16.04 and all my devices have static IP's. my test centos 7 box server002 was using dns 8.8.8.8. corrected dns and now they work. Thanks for stepping me through this.
