NAME
       rndc - name server control utility

SYNOPSIS
       rndc [-b source-address] [-c config-file] [-k key-file] [-s server] [-p port] [-V]
	    [-y key_id] {command}

DESCRIPTION
       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.

OPTIONS
       -b source-address
	   Use source-address as the source address for the connection to the server. Multiple
	   instances are permitted to allow setting of both the IPv4 and IPv6 source addresses.

       -c config-file
	   Use config-file as the configuration file instead of the default, /etc/rndc.conf.

       -k key-file
	   Use key-file as the key file instead of the default, /etc/rndc.key. The key in
	   /etc/rndc.key will be used to authenticate commands sent to the server if the
	   config-file does not exist.

       -s server
	   server is the name or address of the server which matches a server statement in the
	   configuration file for rndc. If no server is supplied on the command line, the host
	   named by the default-server clause in the options statement of the rndc configuration
	   file will be used.

       -p port
	   Send commands to TCP port port instead of BIND 9's default control channel port, 953.

       -V
	   Enable verbose logging.

       -y key_id
	   Use the key key_id from the configuration file.  key_id must be known by named with
	   the same algorithm and secret string in order for control message validation to
	   succeed. If no key_id is specified, rndc will first look for a key clause in the
	   server statement of the server being used, or if no server statement is present for
	   that host, then the default-key clause of the options statement. Note that the
	   configuration file contains shared secrets which are used to send authenticated
	   control commands to name servers. It should therefore not have general read or write
	   access.

       For the complete set of commands supported by rndc, see the BIND 9 Administrator Reference
       Manual or run rndc without arguments to see its help message.

LIMITATIONS
       rndc does not yet support all the commands of the BIND 8 ndc utility.

       There is currently no way to provide the shared secret for a key_id without using the
       configuration file.

       Several error messages could be clearer.
