rndc: connect failed: 127.0.0.1#953: connection refused

Error :  rndc: connect failed: 127.0.0.1#953: connection refused

Cause : rndc.key file doesnt exists, if exists already then its ownership issue

Step 1 : Check whether key file exists if not generate it.

[root@dns ~]# ll /etc/rndc.key
ls: cannot access /etc/rndc.key: No such file or directory
[root@dns ~]# rndc-confgen -a
wrote key file "/etc/rndc.key"
[root@dns ~]#

Step 2 : Change the ownership for rndc.key file from root to named

[root@dns ~]# rndc status
rndc: connect failed: 127.0.0.1#953: connection refused
[root@dns ~]# ll /etc/rndc.key
-rw------- 1 root root 77 May 28 11:07 /etc/rndc.key
[root@dns ~]# chown named:named /etc/rndc.key
[root@dns ~]# /etc/init.d/named restart
