I have Fedora 1.0 and cPanel.

I installed cPanel yesterday and I am having problems with the name servers. My html site is up but ftp fails to connect.

There is something wrong and I don't know how to fix this.
When doing "rndc status" I receive:

rndc: connection to remote host closed
This may indicate that the remote server is using an older version of
the command protocol, this host is not authorized to connect,
or the key is invalid.

try this thread in Cpanel :
