# If a client is subscribed to multiple subscriptions that overlap, e.g. foo/#
|
||
|
|
# and foo/+/baz , then MQTT expects that when the broker receives a message on
|
||
|
|
# a topic that matches both subscriptions, such as foo/bar/baz, then the client
|
||
|
|
# should only receive the message once.
|
||
|
|
# Mosquitto keeps track of which clients a message has been sent to in order to
|
||
|
|
# meet this requirement. The allow_duplicate_messages option allows this
|
||
|
|
# behaviour to be disabled, which may be useful if you have a large number of
|
||
|
|
# clients subscribed to the same set of topics and are very concerned about
|
||
|
|
# minimising memory usage.
|
||
|
|
# It can be safely set to true if you know in advance that your clients will
|

# Topic access is added with lines of the format:
|
||
|
|
#
|
||
|
|
# topic [read|write|readwrite] <topic>
|
||
|
|
#
|
||
|
|
# The access type is controlled using "read", "write" or "readwrite". This
|
||
|
|
# parameter is optional (unless <topic> contains a space character) - if not
|
||
|
|
# given then the access is read/write. <topic> can contain the + or #
|
||
|
|
# wildcards as in subscriptions.
|
||
|
|
#
|
||
|
|
# The first set of topics are applied to anonymous clients, assuming
|
||
|
|
# allow_anonymous is true. User specific topic ACLs are added after a
|
||
|
|
# user line as follows:
|
||
|
|
#
|
||
|
|
# user <username>
|
||
|
|
#
|
||
|
|
# The username referred to here is the same as in password_file. It is
|
||
|
|
# not the clientid.
|
||
|
|
#
|
||
|
|
#
|
||
|
|
# If is also possible to define ACLs based on pattern substitution within the
|
||
|
|
# topic. The patterns available for substition are:
|
||
|
|
#
|
||
|
|
# %c to match the client id of the client
|
||
|
|
# %u to match the username of the client
|
||
|
|
#
|
||
|
|
# The substitution pattern must be the only text for that level of hierarchy.
|
||
|
|
#
|
||
|
|
# The form is the same as for the topic keyword, but using pattern as the
|
||
|
|
# keyword.
|
||
|
|
# Pattern ACLs apply to all users even if the "user" keyword has previously
|
||
|
|
# been given.
|
||
|
|
#
|
||
|
|
# If using bridges with usernames and ACLs, connection messages can be allowed
|
||
|
|
# with the following pattern:
|
||
|
|
# pattern write $SYS/broker/connection/%c/state
|
||
|
|
#
|
||
|
|
# pattern [read|write|readwrite] <topic>
|
||
|
|
#
|
||
|
|
# Example:
|
||
|
|
#
|
||
|
|
# pattern write sensor/%u/data
|
||
|
|
#
|

|

# Bridges

# =================================================================

|
|
|
||
|
|
# A bridge is a way of connecting multiple MQTT brokers together.
|
||
|
|
# Create a new bridge using the "connection" option as described below. Set
|
||
|
|
# options for the bridges using the remaining parameters. You must specify the
|
||
|
|
# address and at least one topic to subscribe to.
|
||
|
|
#
|
||
|
|
# Each connection must have a unique name.
|
||
|
|
#
|
||
|
|
# The address line may have multiple host address and ports specified. See
|
||
|
|
# below in the round_robin description for more details on bridge behaviour if
|
||
|
|
# multiple addresses are used. Note that if you use an IPv6 address, then you
|
||
|
|
# are required to specify a port.
|
||
|
|
#
|
||
|
|
# The direction that the topic will be shared can be chosen by
|
||
|
|
# specifying out, in or both, where the default value is out.
|
||
|
|
# The QoS level of the bridged communication can be specified with the next
|
||
|
|
# topic option. The default QoS level is 0, to change the QoS the topic
|
||
|
|
# direction must also be given.
|
||
|
|
#
|
||
|
|
# The local and remote prefix options allow a topic to be remapped when it is
|
||
|
|
# bridged to/from the remote broker. This provides the ability to place a topic
|
||
|
|
# tree in an appropriate location.
|
||
|
|
#
|
||
|
|
# For more details see the mosquitto.conf man page.
|
||
|
|
#
|
||
|
|
# Multiple topics can be specified per connection, but be careful
|
||
|
|
# not to create any loops.
|
||
|
|
#
|
||
|
|
# If you are using bridges with cleansession set to false (the default), then
|
||
|
|
# you may get unexpected behaviour from incoming topics if you change what
|
||
|
|
# topics you are subscribing to. This is because the remote broker keeps the
|
||
|
|
# subscription for the old topic. If you have this problem, connect your bridge
|
||
|
|
# with cleansession set to true, then reconnect with cleansession set to false
|
||
|
|
# as normal.

# If a bridge has topics that have "out" direction, the default behaviour is to
|
||
|
|
# send an unsubscribe request to the remote broker on that topic. This means
|
||
|
|
# that changing a topic direction from "in" to "out" will not keep receiving
|
