A note about rncd command

This is an optional command and you are recommended to use the above commands only. From the rndc man page:

rndc controls the operation of a name server. It supersedes the ndc utility that was provided in old BIND releases. If rndc is invoked with no command line options or arguments,it prints a short summary of the supported commands and the available options and their arguments. rndc communicates with the name server over a TCP connection,sending commands authenticated with digital signatures. In the current versions of rndc and named,the only supported authentication algorithm is HMAC-MD5,which uses a shared secret on each end of the connection. This provides TSIG-style authentication for the command request and the name server’s response. All commands sent over the channel must be signed by a key_id kNown to the server. rndc reads a configuration file to determine how to contact the name server and decide what algorithm and key it should use.

Please note that rndc does not yet support all the commands of the BIND 8 ndc utility:

1. status – display status of the server.
2. stop – Save pending updates to master files and stop the server.
3. restart – Restart the server.
4. reload – Reload configuration file and zones.

To see status,enter:
# rndc status
Sample outputs:

version: 9.7.3
cpus found: 8
worker threads: 8
number of zones: 18
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 0/0/1000
tcp clients: 0/100
server is up and running

To reload the server,enter:
# rndc reload
To see all options just type rncd:
# rndc
Sample outputs:
