Webmin error when applying configuration after changing BIND DNS server

I just installed Webmin and created a zone which seems to be correct as Check BIND returns

No errors were found in the BIND configuration file / etc / named.conf or in the zone-specific files.

The problem was that after a few hours my domains are still not cleared, but instead of returning UNKNOWN, SERVER immediately delays for about 30 seconds before returning the UNKNOWN SERVER message.

Reading the webmin tutorial, I found that I needed to click Apply Zone and then the error appeared:

Failed to execute NDC command: rndc: neither /etc/rndc.conf nor / etc / rndc.key found

So, after reading about the error found by "rndc-confgen" and creating a key file with "rndc-confgen -a" but it still doesn't work:

Failed to execute NDC command: rndc: connect failed: 127.0.0.1 # 953: connection refused

So, I think this is a service, but I don't know how to start it ... try "rndc-confgen> /etc/rndc.conf", but now I get this error:

Failed to execute NDC command: WARNING: key file (/etc/rndc.key) exists but using default config file (/etc/rndc.conf) rndc: connect failed: 127.0.0.1 # 953: connection refused

So, I guess I still need to start the service, but have no idea how to do it ... I have a Fedora 14 virtual server, there are commands like rndc and rndc-confgen available.
