Bind DNS server not working Centos7

jpedvis · 04-28-2020, 10:50 AM

Hi, I'm trying to setup a DNS server on my Centos7 virtual machine for 3 nested vms. It isn't working. I've tried so many things but nothing is working. Here are my named.conf and zone files:
options {
directory "/var/named/";
allow-query {any; };
forwarders { 208.67.222.222; }; # This one works at home
listen-on { any; };
#forwarders { 10.102.100.21; }; # This one works at Seneca
};
zone "localhost" {
type master;
file "named.localhost";
};
zone "jpedvis" {
type master;
file "mydb-for-jpedvis-ops";
};

$TTL 3D
@ IN SOA host.jpedvis.ops. root.jpedvis.ops.(
2018042901 ; Serial
8H ; Refresh
2H ; Retry
1W ; Expire
1D ; Negative Cache TTL
)

@ IN NS host
@ IN A 192.168.90.1
host IN A 192.168.90.1
vm1 IN A 192.168.90.2
vm2 IN A 192.168.90.3

Thanks!

Hi and welcome to LQ,

You should define the "Bind DNS server not working" by giving more details like logs, answers to queries etc.

Anyway at a first look your zone name is wrong in named.conf. It should be jpedvis.ops instead of just jpedvis according to the zonefile, e.g:

Code:

options {
directory "/var/named/";
allow-query {any; };
forwarders { 208.67.222.222; }; # This one works at home
listen-on { any; };
#forwarders { 10.102.100.21; }; # This one works at Seneca
};
zone "localhost" {
type master;
file "named.localhost";
};
zone "jpedvis.ops" {
type master;
file "mydb-for-jpedvis-ops";
};
