Rndc Errors

[Godfried Duodu]

I have successfully compiled bind-9.1.1 on RH 6.2 and a 2.4.2 kernel and generated a key from the dnssec-keygen command for rndc.conf file.
When I run the rndc reload command I get the error messages: 
"rndc: send remote authenticator: permission denied".
I generated the keys a couple of times and still getting the same error messages. I have included the log messages and the relevant files below for scrutiny.
 What am I doing wrong?
