BIND, managing
From FreeBSDwiki
By far the easiest way to manage BIND is via webmin, where it's all GUI click and drop-down menus. But you should at the very least know how to manage it via command line for systems that you cannot set up webmin on for whatever reason or for those times when webmin fails.
To add records to a zone, you'll need to find that zone's file, edit it to include the record, increase your SOA number and reload your server with
rndc reload
If your server is a slave and you want it to retransfer the records from the master:
rndc retransfer
To check the status of your server:
rndc status
To stop your server:
rndc stop
To flush the DNS cache:
rndc flush
BIND can be a pain to manage properly, and not without reason are there thousands of pages on how to do it written.
