$ rndc
Usage: rndc [-b address] [-c config] [-s server] [-p port]
	[-k key-file ] [-y key] [-r] [-V] command

command is one of the following:

  dumpdb [-all|-cache|-zones|-adb|-bad|-fail] [view ...]

  modzone zone [class [view]] { zone-options }
		Modify a zone's configuration.
		Requires allow-new-zones option.
  notrace	Set debugging level to 0.
  nta -dump
		List all negative trust anchors.
  nta [-lifetime duration] [-force] domain [view]
		Set a negative trust anchor, disabling DNSSEC validation
		for the given domain.

		Using -force prevents the NTA from expiring before its
		full lifetime, even if the domain can validate sooner.
  nta -remove domain [view]
		Remove a negative trust anchor, re-enabling validation
		for the given domain.
  querylog [ on | off ]
		Enable / disable query logging.
  reconfig	Reload configuration file and new zones only.
