DNS on Redhat - rdnc: no server specified and no default

  • 772

The error as shown in the 2 pictures below: no server specified and no default

can't ping www.p0864868.com and can't get the hostname/nslookup result

The configurations for named.conf and the zones files as shown below: named.conf

p0864868.zone file

10-0-0.zone file

Update 1: This is the result after applying the suggestions from "alveso".

The error has been resolved, but I still can't ping my own domain www.p0864868.com (10.0.0.1) nor can I do host or nslookup lookups as shown on previous pictures.

named service

I also attached my the changes that I made to my named.conf as well as my resolve.conf configs as shown below: named.conf that has been edited as suggested by alveso

Resolve.conf as reference in case you want to see it

Update 2: I turned on logging by typing "rndc querylog" with the output as below when I pinged p0864868.com rndc log

Update 3: changed permission of 10-0-0.zone and p086868.zone to 644 named:named Still can't ping www.p0864868.com or execute host command. It says something like Network Unreachable. network unreachable

  1. 1 Find key-name and key-value. Open "/etc/rndc.key"

    key "<key-name>" {
  algorithm hmac-md5;
  secret "<key-value>";
};

    2 Configuring "/etc/rndc.conf":

    key "<key-name>" {
  algorithm hmac-md5;
  secret "<key-value>";
};
options {
  default-server  localhost;
  default-key     "<key-name>";
};

    3 Configuring "/etc/named.conf". Check control section:

    controls {
  inet 127.0.0.1 allow { localhost; } keys { <key-name>; };
};
