# Useful files to keep on your Raspberry Pi
|
||||||
|
|
||||||
|
Use these files as examples and modify them to fit your needs.
|
||||||
|
|
||||||
|
Place the executable files in `/usr/local/sbin` and save `index.txt` as
|
||||||
|
`/root/index.html`.
|
||||||
|
|
||||||
|
## index.txt
|
||||||
|
|
||||||
|
This file contains the website that is shown when you stop the dashboard. It gets
|
||||||
|
copied into the webroot of your webserver -- make sure your webserver reads
|
||||||
|
`index.html` files **before** `index.php` files.
|
||||||
|
|
||||||
|
## dashboard
|
||||||
|
|
||||||
|
Executable file. Make sure to `chmod +x` this file.
|
||||||
|
|
||||||
|
Start or stop the dashboard with this command. This toggles the systemd service
|
||||||
|
|
||||||
|
- php7.3-fpm.service
|
||||||
|
|
||||||
|
Usage:
|
||||||
|
|
||||||
|
```
|
||||||
|
/usr/local/sbin/dashboard {on|off}
|
||||||
|
```
|
||||||
|
|
||||||
|
## hotspot
|
||||||
|
|
||||||
|
Executable file. Make sure to `chmod +x` this file.
|
||||||
|
|
||||||
|
Start or stop your hotspot. This toggles the systemd services
|
||||||
|
|
||||||
|
- mmdvmhost.timer
|
||||||
|
- mmdvmhost.service
|
||||||
|
|
||||||
|
Additionally it starts or stops the dashboard command mentioned above.
|
||||||
|
|
||||||
|
Usage:
|
||||||
|
|
||||||
|
```
|
||||||
|
/usr/local/sbin/hotspot {on|off}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Start and stop the hotspot via Cron
|
||||||
|
|
||||||
|
Place these lines in your `/etc/crontab` to automatically start and/or stop
|
||||||
|
your hotspot.
|
||||||
|
|
||||||
|
```
|
||||||
|
30 6 * * 1-5 root /usr/local/sbin/hotspot off
|
||||||
|
0 18 * * 1-5 root /usr/local/sbin/hotspot on
|
||||||
|
```
|
||||||
|
|
||||||
|
That might stop the hotspot at 6:30 and start it again at 18:00, Monday to Friday.
|
||||||
|
|
||||||
|
## shrinklog
|
||||||
|
|
||||||
|
Executable file. Make sure to `chmod +x` this file.
|
||||||
|
|
||||||
|
This command shrinks the MMDVMHost log file to a limited number of important
|
||||||
|
lines.
|
||||||
|
|
||||||
|
The code of this was primarily taken from [Pi-Star][shrinklog] and modified.
