My mistake

I forgot the named service never started so you won't get any output.

Alhumdulillah!

So nice of you dear. After disabling selinux, named service started atlast!

Thanks a lot to both of you!

now I am going ahead in DNS configuration if I find difficult I will come back here.

Can you check the port no you are using for named.conf
It should be 53 instead of 953 as shown in the error
Please note that 953 is the port rndc is listening on, not the port that named is listening

@OP
Disable SELinux temporarily, to verify that it's the culprit
If you have used yum to install bind related stuff, you shouldn't have such problems

I have another query:

When I have two separately connected PCs with each other under domain example.com
Where PC1 192.168.1.91 is dns server and PC2 192.168.1.93 is its client, they can dig, nslookup each other with name and IP both.

But when I Put PC1 (DNS server) on our LAN then no any client able to dig via this dns server.

LAN snacerio:


DSL router: 192.168.1.1 (itself is a DNS server for internet provided by PTCL internet provider)
192.168.1.2 to onwards we have clients.

Now both PC1 and PC2 are on this local net. I have defined in client /etc/resolv.conf
search example.conf
nameserver 192.168.1.91 # DNS for local net
nameserver 192.168.1.1 # dns for internet

clients can ping www.google.com but can't dig or ping client1.example.com.

Yes when I disable SELinux it works, when I enable SELinux it named service doesn't start.

Yes I have installed it via yum, but I faced that problem don't know why

I'm not using SELinux, but from this doc, looks like that if you want to keep SELinux enabled (you should as it's a good security measure), you can either use:
Code:
named_disable_trans=1
to disable SELinux just for named, or use:
Code:
chcon -R system_u:object_r:named_cache_t /var/named/chroot/var/named/data
to relabel the directory in question

I'm sure that I understand what you mean with the above. When can a client resolve a hostname and when it can't?

BTW, you have an error in /etc/resolv.conf. It should read:
Code:
search example.com

Above issue also resolved when I stopped iptables service on DNS server. Thanks

HI friends,

* If you find error in named configuration file (master file not loaded, named.conf not found) make sure Did you create the named.conf in proper location. Actual location is "/var/named/chroot/etc/named.conf"

If you are not created in this location please move named.conf to this location, then try to start named service.

This is when you have installed bind-chroot rpm

You need to make sure which bind rpm are you using for BIND configuration. Verify the logs properly as it would give more information about the error before taking any step.

@nanasupriatna0902

Please start you own thread giving more details about your problem.
Especially post the /var/named/reverse.belogix.com zonefile, as it's the one that has errors:

dns_rdata_fromtext: /var/named/reverse.belogix.com:8: near eol: unexpected end of input

zone 0.168.192.in-addr.arpa/IN: not loaded due to errors.
_default/0.168.192.in-addr.arpa/IN: unexpected end of input
