.. _mod-noudp:
``noudp`` — No UDP response
===========================
The module sends empty truncated reply to a query over UDP. Replies over TCP
are not affected.
Example
-------
To enable this module for all configured zones and every UDP reply::
template:
- id: default
global-module: mod-noudp
Or with specified UDP allow rate::
mod-noudp:
- id: sometimes
udp-allow-rate: 1000 # Don't truncate every 1000th UDP reply
template:
- id: default
module: mod-noudp/sometimes
Module reference
----------------
::
mod-noudp:
- id: STR
udp-allow-rate: INT
udp-truncate-rate: INT
.. NOTE::
Both *udp-allow-rate* and *udp-truncate-rate* cannot be specified together.
.. _mod-noudp_udp-allow-rate:
udp-allow-rate
..............
Specifies frequency of UDP replies that are not truncated. A non-zero value means
that every N\ :sup:`th` UDP reply is not truncated.
.. NOTE::
The rate value is associated with one UDP worker. If more UDP workers are
configured, the specified value may not be obvious to clients.
*Default:* not set
.. _mod-noudp_udp-truncate-rate:
udp-truncate-rate
.................
Specifies frequency of UDP replies that are truncated (opposite of
:ref:`udp-allow-rate <mod-noudp_udp-allow-rate>`). A non-zero value means that
every N\ :sup:`th` UDP reply is truncated.
.. NOTE::
The rate value is associated with one UDP worker. If more UDP workers are
configured, the specified value may not be obvious to clients.
*Default:* 1
