there's no 'rndc start' since rndc is designed to work across a network,
and if named is not running, neither is rndc.

you can do 'named' to start it (named -u bind if you're running as the
user bind... there are more options in the man page for 'named'.)

you might need to generate an rndc key, or put a 'controls' statement in
your named.conf; other than that your zone files and named configuration
file should work fine.

well the version of bind 9 that comes with it (you might want to upgrade
to a newer version) probably comes with an init script called 'bind' or
'named', which you can use to start, stop, and possibly reload named.

i would recommend _not_ uninstalling bind9 and installing bind 8, but
you should upgrade to bind 9.2.0 if your version is older than that.
