Hi all
I've just installed bind server, but the problem is, I cannot resolve localhost, the box where bind server itself is installed. I can resolve all other machines in lan. Why?
Here are the file details:
Code:
[root@srv ~]# ip addr show enp3s0
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether d0:50:99:6a:a2:40 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.7/24 brd 192.168.1.255 scope global enp3s0
valid_lft forever preferred_lft forever
inet6 fe80::d250:99ff:fe6a:a240/64 scope link
valid_lft forever preferred_lft forever
Code:
[root@srv ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

[root@srv ~]# dig c72
c72.nixquery.lan. 259200 IN A 192.168.1.102
[root@srv ~]# dig w10
w10.nixquery.lan. 259200 IN A 192.168.1.100
[root@srv ~]# dig rtr
rtr.nixquery.lan. 259200 IN A 192.168.1.1
But if I dig srv, i.e., localhost, It wont resolve. It resolves if I give FQDN though.
Code:
[root@srv ~]# dig srv
. 516347 IN NS f.root-servers.net.
. 516347 IN NS i.root-servers.net.
. 516347 IN NS j.root-servers.net.

. 516347 IN NS e.root-servers.net.
. 516347 IN NS k.root-servers.net.
. 516347 IN NS m.root-servers.net.
. 516347 IN NS b.root-servers.net.

. 516347 IN NS c.root-servers.net.

[root@srv ~]# dig srv.nixquery.lan
srv.nixquery.lan. 259200 IN A 192.168.1.7
Thanks.
