Dns issue rndc: connect failed: 127.0.0.1#953: connection refused

[root@testserver ~]# /usr/local/cpanel/scripts/fixrndc
warn [fixrndc] /usr/sbin/rndc status failed: WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf)rndc: connect failed: 127.0.0.1#953: connection refused

The problem was that you had portreserve reserving port 953 so named could not bind to the port. I moved the offending file out of the way, restarted portreserve & named and was able to resolve the error for you:

[root@testserver ~]# netstat -tplanu|grep :953|grep LIST
[root@ testserver  ~]# cat /etc/portreserve/named/rndc/tcp
[root@ testserver  ~]# mv /etc/portreserve/named /etc/portreserve/.named
[root@ testserver 1 ~]# /etc/init.d/portreserve restart
Stopping portreserve: [ OK ]
Starting portreserve: (not starting, no services registered)
[root@ testserver  ~]# /etc/init.d/named restart
Stopping named: [ OK ]
Starting named: [ OK ]
[root@ testserver  ~]# netstat -tplanu|grep :953|grep LIST

[root@ testserver  ~]# rndc reload

Now run this command,
[root@ testserver  ~]# /usr/local/cpanel/scripts/fixrndc
