.. _Console: Working with the dnsdist Console ================================ dnsdist can expose a commandline console over an encrypted tcp connection for controlling it, debugging DNS issues and retrieving statistics. The console can be enabled with :func:`controlSocket`: .. code-block:: lua controlSocket('192.0.2.53:5199') Enabling the console without encryption enabled is not recommended. Note that encryption requires building dnsdist with libsodium support enabled. Once you have a libsodium-enabled dnsdist, the first step to enable encryption is to generate a key with :func:`makeKey`:: $ ./dnsdist -l 127.0.0.1:5300 [..] > makeKey() setKey("ENCODED KEY") Then add the generated :func:`setKey` line to your dnsdist configuration file, along with a :func:`controlSocket`: .. code-block:: lua controlSocket('192.0.2.53:5199') -- Listen on this IP and port for client connections setKey("ENCODED KEY") -- Shared secret for the console Now you can run ``dnsdist -c`` to connect to the console. This makes dnsdist read its configuration file and use the :func:`controlSocket` and :func:`setKey` statements to set up its connection to the server. If you want to connect over the network, create a configuration file with the same two statements and run ``dnsdist -C /path/to/configfile -c``. Alternatively, you can specify the address and key on the client commandline:: dnsdist -k "ENCODED KEY" -c 192.0.2.53:5199 .. warning:: This will leak the key into your shell's history and is **not** recommended. Since 1.3.0, dnsdist supports restricting which client can connect to the console with an ACL: .. code-block:: lua controlSocket('192.0.2.53:5199') setConsoleACL('192.0.2.0/24') The default value is '127.0.0.1', restricting the use of the console to local users. Please make sure that encryption is enabled before using :func:`addConsoleACL` or :func:`setConsoleACL` to allow connection from remote clients. Even if the console is restricted to local users, the use of encryption is still strongly advised to prevent unauthorized local users from connecting to the console.
