I have been working for come next month for 3 years trying to setup a home server to handle our own websites . So on a spur of the moment type deal i dumped centos 7 and installed centos 8 about 6 times due to errors of the AppStream but finally got it. After words i went on the hunt for help on setting up centos 8 server and came across your tutitorial and it is simply the best that i found in the 3 years i have been working on this project. most everyone else leaves out details that are vital and you have to go on a hunt to try and to find the missing pieces and then you loose track of where you where. thank you for including everything i needed to set my server up. you are greatly appreciated by me for doing such a wonderful job on sharing the right information to help someone like me. again i can’t thank you enough.

In reply to Arun Kumar. Hi Arun, To use the DNS server on client machines, you have to add DNS server IP address (for linux machine you can add it in resolv.conf & on windows machine edit network settings for active NIC and add DNS server ip there)

but question is how other hosts in network will use this DNS server for name resolution
setting up just DN S is of no use till we use for name resolution for servers in networks
how can we do that

if the web and mail server would be in the same pc of the dns would they have the same ip?
www IN A 192.168.43.50 –>.35
mail IN A 192.168.43.6 –>.35

how would the reverse file be?

I have that doubt

In step 4 each of the PTR records need to end in a trailing .(dot) otherwise the nslookup for the www or mail will respond with the wrong fqdn along the lines of

# nslookup 192.168.43.50
50.43.168.192.in-addr.arpa name = ‘www.linuxtechi.local.43.168.192.in-addr.arpa.’

Sorry formatting on the previous post was terrible…. hopefully this one will be better

Make sure the IP address of the machine that you setup bind on is 10.19.182.19, Make sure the firewall of the machine that you setup bind on has port 53 open, double check the entry in your nokia.local.db config file is test IN A 10.10.182.X Confirm that you restarted named after making the edits to the config files

Try doing the the following test on the machine that is running bind and see if you get a correct response

[root@bindMachine ~]# nslookup

> server localhost

> test.nokia.local

Hi,
I followed each step and configured the DNS-BIND but while doing nslookup from client I am getting below NXDOMAIN error

[root@nc0521node02 ~]# nslookup test.nokia.local
Server: 10.10.183.19
Address: 10.10.183.19#53

** server can’t find test.nokia.local: NXDOMAIN

Can anyone please help to resolve this
