Configuratie van de master node

Configured on the MSL server. Requisite packages:

 sudo apt install git sudo screen python3
 python3 -m ensure pip
 pip3 install configargparse
 pip3 install paho-mqtt
 pip3 install pidfile daemon setproctitle

Installatie:

 cd /usr/local
 git clone https://github.com/MakerSpaceLeiden/AccesSystem.git

Initiele uitrollen configuratie:

 sudo mkdir /usr/local/master
 ... change to some neutered user ....
 cp acnode.ini /usr/local/etc/master
 cp sample-keydb.txt /usr/local/etc/master/keydb.txt
 chown master:master -R /usr/local/etc/master
 chmod -R go-rwx /usr/local/etc/master

Starten, restart, stop, etc

Usual systemd:

 sudo sudo systemctl restart master-access

Rekeying an upgraded/replaced existing node

After an upgrade or replacement - the node may need to re-generate its private key. In that case the master will no longer recognise/accept it. So you need to rekey the master.

Stop the sever; and edit

   vi /usr/local/AccesSystem/Master/trustdb.txt

and remove the line for that node; then restart the server.

Adding a new node

A new node won't be recognised (And allowed to (re)key) if it is not in acnode-prod.ini. So add it there

   vi /usr/local/AccesSystem/Master/trustdb.txt

And edit the line

   secrets = [ woodlathe, lintzaag, tablesaw, planer, jointer, lights, compressor, tussendeur, voordeur, spacedeur, byebye, XXXX ]

where XXXX is the name of the node you are adding. Then restart the server; and it should repair (power cycle the node to speed this up). Check trustdb.txt to see it getdding added.


Debugging

Watch the MQTT log to see what is going on.
