This is my config file /etc/mosquitto/mosquitto.conf

# Place your local configuration in /etc/mosquitto/conf.d/
#
# A full description of the configuration file is at
# /usr/share/doc/mosquitto/examples/mosquitto.conf.example

pid_file /var/run/mosquitto.pid

persistence true
persistence_location /var/lib/mosquitto/

log_dest file /var/log/mosquitto/mosquitto.log


include_dir /etc/mosquitto/conf.d

This is my passwd file created using sudo mosquitto_passwd -c /etc/mosquitto/password ananth

ananth:$6$pW5LFAJ/J0bzSHyz$XZsN5MwVc80JqITYvg8qtLxkjWWF2AEzYtoVJpXV9VbjXE5YSXFYC/umWXocj2ScQO/ztFsovgq8o/h00zQTSg==

This is my local config file present in /etc/mosquitto/conf.d/auth.conf

allow_anonymous false
password_file /etc/mosquitto/password

When I run mosquitto_sub -t test or mosquitto_pub -t test -m "Message", Broker is not refusing the connection due to un authentication

I also tried restarting mosquitto using sudo service mosquitto restart

On Ubuntu 16.04 on oracle virtual machine

Am I missing something ?

  • Run ps -efc | grep mosquitto to check that mosquitto is being run with the -c config option pointing to the config file. iirc mosquitto on 16.04 doesn't default to use the config file – hardillb Jul 12 '19 at 18:23
  • Yeah I can see this mosquit+ 15995 1 TS 19 Jul12 ? 00:00:09 /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf – Ananth Sathvick Jul 12 '19 at 18:52
  • Even tried running sudo mosquitto -c /etc/mosquitto/mosquitto.conf – Ananth Sathvick Jul 12 '19 at 18:57
  • What version of mosquitto? and what is the in the logs when the client connects – hardillb Jul 12 '19 at 19:02
  • mosquitto version 1.6.3 and MQTT v3.1.1 broker .Log when the client connects - New client connected from 127.0.0.1 as mosq/Nc2cy7FMx9SI2fab8U (p2, c1, k60). – Ananth Sathvick Jul 12 '19 at 19:04

I also faced the same issue in Ubuntu 18.04. For me, stopping and starting the service worked. Instead of:

sudo service mosquitto restart

I used

sudo service mosquitto stop
sudo service mosquitto start

And I was able to see the effect of changes made in the local config.

Running the status command sudo service mosquitto status gives the following output.

After service restart

mosquitto.service - LSB: mosquitto MQTT v3.1 message broker
Loaded: loaded (/etc/init.d/mosquitto; generated)
Active: active (exited) since Wed 2020-03-11 17:36:27 IST; 4s ago
 Docs: man:systemd-sysv-generator(8)
Process: 3884 ExecStop=/etc/init.d/mosquitto stop (code=exited, status=0/SUCCE
Process: 3890 ExecStart=/etc/init.d/mosquitto start (code=exited, status=0/SUC

After service stop and start

mosquitto.service - LSB: mosquitto MQTT v3.1 message broker
Loaded: loaded (/etc/init.d/mosquitto; generated)
Active: active (running) since Wed 2020-03-11 17:36:41 IST; 2s ago
 Docs: man:systemd-sysv-generator(8)
Process: 3932 ExecStop=/etc/init.d/mosquitto stop (code=exited, status=0/SUCCE
Process: 3965 ExecStart=/etc/init.d/mosquitto start (code=exited, status=0/SUC
Tasks: 1 (limit: 4915)
CGroup: /system.slice/mosquitto.service
       └─3971 /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf

After service is restarted using restart, status shows Active: active (exited) and after service stop and start, status shows Active: active (running)

So, I think restarting the service using restart does not reloads the config file and so anything added in local config (in your case, it is /etc/mosquitto/conf.d/auth.conf) does not have any effect.

These were also observed when I made changes in the main config, i.e., /etc/mosquitto/mosquitto.conf and used service restart which had no effect. But, service stop and start worked.

Still Don't know what the problem was but I uninstalled mosquitto* and reinstalled mosquitto*

Uninstalling

sudo apt-get remove --auto-remove mosquitto*
sudo apt-get purge --auto-remove mosquitto*

Installing

sudo apt install mosquitto*

And this worked for me (Ubuntu 16.04, Oracle Virtual Box(Windows Host), mosquitto version 1.6.3 and MQTT v3.1.1 broker )
