1073N/A<

1073N/A controls the operation of a name
1073N/A server. It supersedes the <
span><
strong class="command">ndc</
strong></
span> utility
1073N/A that was provided in old BIND releases. If
1073N/A <
span><
strong class="command">rndc</
strong></
span> is invoked with no command line
1073N/A options or arguments, it prints a short summary of the
1073N/A supported commands and the available options and their
1073N/A<

strong class="command">rndc</

1073N/A communicates with the name server
1073N/A over a TCP connection, sending commands authenticated with
1073N/A digital signatures. In the current versions of
1073N/A <
span><
strong class="command">rndc</
strong></
span> and <
span><
strong class="command">named</
strong></
span>,
1073N/A the only supported authentication algorithm is HMAC-MD5,
1073N/A which uses a shared secret on each end of the connection.
1073N/A This provides TSIG-style authentication for the command
1073N/A request and the name server's response. All commands sent
1073N/A over the channel must be signed by a key_id known to the
1073N/A<

strong class="command">rndc</
strong></
span>
1073N/A reads a configuration file to
1073N/A determine how to contact the name server and decide what
1073N/A algorithm and key it should use.
