2N/A controls the operation of a name
2N/A server. It supersedes the <
span><
strong class="command">ndc</
strong></
span> utility
2N/A that was provided in old BIND releases. If
2N/A <
span><
strong class="command">rndc</
strong></
span> is invoked with no command line
2N/A options or arguments, it prints a short summary of the
2N/A supported commands and the available options and their
2N/A<
p><
span><
strong class="command">rndc</

2N/A communicates with the name server
2N/A over a TCP connection, sending commands authenticated with
2N/A digital signatures. In the current versions of
2N/A <
span><
strong class="command">rndc</
strong></
span> and <
span><
strong class="command">named</
strong></
span> named
2N/A the only supported authentication algorithm is HMAC-MD5,
2N/A which uses a shared secret on each end of the connection.
2N/A This provides TSIG-style authentication for the command
2N/A request and the name server's response. All commands sent
2N/A over the channel must be signed by a key_id known to the
2N/A<
p><
span><
strong class="command">rndc</
strong></
span>
2N/A reads a configuration file to
2N/A determine how to contact the name server and decide what
2N/A algorithm and key it should use.
