<title>Description</title>
|

<para><command>mosquitto_pub</command> is a simple MQTT version 5/3.1.1
|

client that will publish a single message on a topic and

<title>Encrypted Connections</title>
|
|
<para><command>mosquitto_pub</command> supports TLS encrypted
|
|
connections. It is strongly recommended that you use an encrypted
|
|
connection for anything more than the most basic setup.</para>
|
|
<para>To enable TLS connections when using x509 certificates, one of
|
|
either <option>--cafile</option> or <option>--capath</option> must
|
|
be provided as an option.</para>
|
|
<para>To enable TLS connections when using TLS-PSK, you must use the
|
|
<option>--psk</option> and the <option>--psk-identity</option>
|
|
options.</para>

<title>Options</title>
|
|
<para>The options below may be given on the command line, but may also
|
|
be placed in a config file located at
|
|
<option>$XDG_CONFIG_HOME/mosquitto_pub</option> or
|
|
<option>$HOME/.config/mosquitto_sub</option> with one pair of
|
|
<option>-option <replaceable>value</replaceable></option>
|
|
per line. The values in the config file will be used as defaults
|
|
and can be overridden by using the command line. The exceptions to
|
|
this are the message type options, of which only one can be
|
|
specified. Note also that currently some options cannot be negated,
|
|
e.g. <option>-S</option>. Config file lines that have a
|
|
<option>#</option> as the first character are treated as comments
|
|
and not processed any further.</para>

resort to using this option in a production

environment, your setup is at fault and there is no
