##### DASH #####
|
||||
|
||||
This is the minimum viable dashboard to be useful. It provides the
|
||||
following information, refreshed every 30s:
|
||||
|
||||
* Node Callsign
|
||||
* Node TX Frequency
|
||||
* Node IP Address
|
||||
* Currently Linked Reflector
|
||||
|
||||
It also has a button to disconnect the currently connected reflector, and a text
|
||||
field and button to connect to another reflector. Only the first 7 characters
|
||||
entered here will be used, the rest will be discarded. If the reflector entered
|
||||
is not valid (or not included in the gwys.txt file) the command will still run
|
||||
but have no effect.
|
||||
|
||||
To access the dashboard, simply point a browser at the Hotspot's IP address or
|
||||
at http://<hostname>.local/ (on the same subnet).
|
||||
|
||||
|
||||
To install, run the following command after the main installation:
|
||||
|
||||
sudo make installdash
|
||||
|
||||
Note that this will install the PIP package for Python3 if not installed, and
|
||||
it will also install the libconf Python module. These are not uninstalled by the
|
||||
uninstall script, but as these are idempotent commands, there is no issue running
|
||||
the install if they are already present.
|
||||
|
||||
|
||||
To uninstall, run the following:
|
||||
|
||||
sudo make uninstalldash

##### DASHBOARD.README #####
|
||||
|
||||
A web-based dashboard can be enabled. You can supply your own index.php file,
|
||||
or a functional dashboard can be provide. If no index.php file is in the
|
||||
build directroy when try to install the dashboard, the installation will fail.
|
||||
To get started, copy the "example.php" file to "index.php".
|
||||
|
||||
The example.php file is a good place to start, if you want to create your own
|
||||
by adding features to your dashboard. This dashboard include a <form> with
|
||||
a button to send any URCALL to your gateway.
|
||||
|
||||
To install, run the following command after you have created an index.php file:
|
||||
|
||||
sudo make installdash
|
||||
|
||||
Note that this will install a php web server and all necessary packaged needed
|
||||
for the server. To uninstall, run the following:
|
||||
|
||||
sudo make uninstalldash
|
||||
|
||||
These installed packaged are not uninstalled by the uninstall script. It will
|
||||
only shut down the php web server.
|
||||
|
||||
Likewise, the index.php file will not be erased in the build directory when you
|
||||
uninstall the dashboard, so if you've done a "git pull" and have noticed that
|
||||
there was a new example.php file downloaded, you may want to copy the newer
|
||||
example.php file to index.php.
|
||||
|
||||
One the dashboard server is running, simply point a browser at the Hotspot's IP
|
||||
address or at http://<hostname>.local/ (on the same subnet).
|
||||
|
||||
Please note that this is a very simple server and is not recommended for the
|
||||
world wide web. If you want a robust dashboard accessible from the web, you
|
||||
will want to use a robust server, like apache, and a different index.php file.
