10139N/A controls the operation of a name
10139N/A server. It supersedes the <
span><
strong class="command">ndc</
strong></
span> utility
10139N/A that was provided in old BIND releases. If
10139N/A <
span><
strong class="command">rndc</
strong></
span> is invoked with no command line
10139N/A options or arguments, it prints a short summary of the
10139N/A supported commands and the available options and their
10139N/A<

10139N/A communicates with the name server
10139N/A over a TCP connection, sending commands authenticated with
10139N/A digital signatures. In the current versions of
10139N/A <
span><
strong class="command">rndc</
strong></
span> and <
span><
strong class="command">named</
strong></
span>,
10139N/A the only supported authentication algorithm is HMAC-MD5,
13570N/A which uses a shared secret on each end of the connection.
10139N/A This provides TSIG-style authentication for the command
10139N/A request and the name server's response. All commands sent
10139N/A over the channel must be signed by a key_id known to the

10139N/A There is currently no way to provide the shared secret for a
