Re: [mosquitto-dev] Connections refused in mosquitto 1.4.2 on raspian

Hi Bernd,

Have you tried connecting with another tool, e.g. mosquitto_sub? Please try from the same machine you are attempting to connect from and with the same host/ip address.

First a start log output of mosquitto:

pi@raspberrypi ~ $ sudo mosquitto -v -c /etc/mosquitto/mosquitto.conf
1433677377: mosquitto version 1.4.2 (build date Mon, 18 May 2015 15:25:19 +0100) starting

1433677377: Opening ipv6 listen socket on port 1883.
1433677377: Opening ipv4 listen socket on port 8883.
1433677377: Opening ipv6 listen socket on port 8883.

Second a netstat -lnp
i@raspberrypi ~ $ sudo netstat -lnp

I am not using TLS as far as I know.

Does this help?
