hostname=${fqdn%%.*}
echo "Changing FQDN to $fqdn, hostname to $hostname"
sudo hostnamectl set-hostname $hostname

Synology Surveillance Station - Move Camera to PTZ Preset Depending on Home Mode
#!/usr/bin/env python3
"""
Scroll to the bottom and change your IP address (if running the script from another host), Surveillance Station account and password,
the camera name and presets. It shouldn't be too hard to add some other cameras and presets if you know a bit of programming.
Add a task in DSM Task Scheduler to execute this file every minute.
In case you want to extend this script further to do other stuff, the complete documentation for the Surveillance Station Web API can be found at:
