Hi Stefano, This is part incorrect behaviour, part difficult to deal with behaviour. The connection information in $SYS being saved to mosquitto.db is incorrect and this has already been fixed for version 0.16.
The other side of the behaviour you are seeing is most probably around the direction of the topics. In you specify an "in" topic (i.e. this broker subscribes to a topic on the remote broker) and then disconnect, the remote broker will keep that subscription information because by default bridge connections have cleansession set to false. If you subsequently reconnect the bridge, everything will operate as you would expect. If instead you change the topic direction to "out" and then reconnect, the remote broker will still have your subscription and so still send you messages even though your configuration doesn't ask for them. The same problem exists for "both" type topics changing to "out". Changes in 0.16 help here too - any topics to be bridged with "out" direction will have an UNSUBSCRIBE command sent to the remote broker to ensure that any existing subscriptions are removed. The port settings should not be saved and should make no difference to the above behaviour. In the short term as you are experimenting the solution is to either delete mosquitto.db on each restart with a changed configuration or set "persistence" in mosquitto.conf to false. I hope this helps, Roger On Tue, Jun 12, 2012 at 2:01 PM, stefano costa <[email protected]> wrote: > I'm testing some features of mosquitto as a broker, and I'm now realizing > that when I change configurations items in "mosquitto.conf" and stop/start > mosquitto (daemon) not everything can be considered updated.
