• Log in to the gateway

• `cd /etc/mosquitto`

• `sudo vi mosquitto.conf` <You may be prompted for your password; enter it>

• On the keyboard, press `i`

• At the top of the mosquitto.conf file, enter the following:

pid_file /var/run/mosquitto.pid
user root
port 1883
protocol mqtt
log_dest file /var/log/mosquitto.log
log_type error
log_type warning
log_type notice
log_type information
log_type subscribe
connection_messages true
log_timestamp true
allow_anonymous false
password_file /etc/mosquitto/passwords.txt

• On the keyboard, press `esc`

• On the keyboard, type `:wq` and press `enter`

• `sudo mosquito_passwd -c passwords.txt cool_dude` `wears_sunglasses`

• After creating the password file and entering the first username and password, to enter more usernames and passwords:

• `cd ..`

• `cd ..`

• `sudo /etc/init.d/mosquitto stop`

• `sudo /etc/init.d/mosquitto start -c /etc/mosquitto/mosquitto.conf`

• Mycorrhiza should now be able to find and connect to the GW Broker
