Michael Gisbers 8375673d93 global-functions: implement notifications via Matrix 
Matrix is an open network for secure, decentralized communication - and
it has a web api.

A warning on message type: Using 'm.notice' breaks rendering on Element
for Android (no fixed width font) and does not pop up desktop
notification. Thus we use 'm.text'. Should be safe as we do not send the
messages in response to other messages.

Use wireless network with daily psk

◀ Go back to main README

🛈 This script can not be used on its own but requires the base installation. See main README for details.

Description

This script is supposed to provide a wifi network which changes the passphrase to a pseudo-random string daily.

Requirements and installation

Just install this script.

Depending on whether you use CAPsMAN (/ caps-man) or local wireless interface (/ interface wireless) you need to install a different script.

For CAPsMAN:

$ScriptInstallUpdate daily-psk.capsman;

For local interface:

$ScriptInstallUpdate daily-psk.local;

And add schedulers to run the script:

/ system scheduler add interval=1d name=daily-psk-nightly on-event="/ system script run daily-psk.local;" start-date=may/23/2018 start-time=03:00:00;
/ system scheduler add name=daily-psk-startup on-event="/ system script run daily-psk.local;" start-time=startup;

These will update the passphrase on boot and nightly at 3:00.

Configuration

The configuration goes to global-config-overlay, these are the parameters:

  • DailyPskMatchComment: pattern to match the wireless access list comment
  • DailyPskSecrets: an array with pseudo random strings

Then add an access list entry:

/ interface wireless access-list add comment="Daily PSK" interface=wl-daily private-pre-shared-key="ToBeChangedDaily";

Also notification settings are required for e-mail, matrix and/or telegram.
