Mosquitto

Mosquitto is an MQTT server. I configured it for simple use as a message relay for a IoT camera.

logrotate doesn't like mosquitto constantly writing to it's logfile while it tries to compress. Workaround this by changing /etc/logrotate.d/mosquitto's compress line to delaycompress.

Authentication is via a user/password for simplicity (although mosquitto is capable of using SSL/TLS with certificates). I created users with the command:

sudo mosquitto_passwd -c /etc/mosquitto/pwfile <username>

I copy pasted this config and edited the listener line, and removed one of the log_dest lines. Seems to work adequately, but nothing private is being sent over this setup.
