===== Tom 2E0JJI's bpqmonweb =====
Tom has created a superb web application to monitor a BPQ or Xrouter node.

This involves installing a web server & MQTT broker and configuring the whole lot. This is on a Pi running Raspberry Pi OS 12 - let's start with installing the required packages:

<code> sudo apt install -y git nginx mosquitto </code>

Grab Tom's repository and copy everything into the web server

<code>
mkdir ~/src; cd ~/src
git clone https://github.com/packethacking/bpqmonweb.git
cd ~/src/bpqmonweb
sudo rm /etc/nginx/sites-enabled/default
sudo cp nginx/nginx.conf /etc/nginx/sites-enabled/bpqmonweb
sudo cp *.html /usr/share/nginx/html/
sudo cp *.css /usr/share/nginx/html/
sudo cp *.js /usr/share/nginx/html/
</code>

Now we need to add an entry to our hosts file so the nginx proxy knows where mosquitto is located on the network; this is already set in the nginx config so it's cleaner to add it here rather than edit the files pulled from git
<code>echo "127.0.0.1	mosquitto" | sudo tee -a /etc/hosts</code>

Then we need to set up mosquitto users - replace the supersecretbpqmqttpassword with something "secret" so other people can't publish to your MQTT server!
<code>
echo "linbpquser:supersecretbpqmqttpassword" | sudo tee /etc/mosquitto/bpqpasswd
echo "bpqmonweb:bpqmonweb" | sudo tee /etc/mosquitto/webpasswd
sudo mosquitto_passwd -U /etc/mosquitto/bpqpasswd
sudo mosquitto_passwd -U /etc/mosquitto/webpasswd
</code>

and create some configuration files for mosquitto to enable publishing and websocket access
<code>
echo 'per_listener_settings true

listener 1883
password_file /etc/mosquitto/bpqpasswd
allow_anonymous false

listener 9001
protocol websockets
password_file /etc/mosquitto/webpasswd
acl_file /etc/mosquitto/webaclfile
allow_anonymous false' | sudo tee /etc/mosquitto/conf.d/bpqmonweb.conf
</code>

and create an access control list so publishing to the publicly-available user can only read the topic
<code>
echo 'user bpqmonweb
topic read PACKETNODE/ax25/trace/bpqformat/#' | sudo tee /etc/mosquitto/webaclfile
</code>

Now we need to tell LinBPQ to publish to the MQTT broker; add the following lines to your /etc/bpq32.cfg
Remember to use the super secret password you created above; the hostname "mosquitto" is resolved from /etc/hosts
<code>
MQTT=1
MQTT_HOST=mosquitto
MQTT_PORT=1883
MQTT_USER=linbpquser
MQTT_PASS=supersecretbpqmqttpassword
</code>

then restart all the services we've tinkered with
<code>
sudo systemctl restart mosquitto.service
sudo systemctl restart linbpq.service
sudo systemctl restart nginx.service
</code>

Now you can access the web server and watch the packet racket!
<code> http://your.pi.ip.address </code>
