Permission Correction

Python-based service to change files within a folder to the desired owner and permission level. Originally developed to correct owern/permissions for files uploaded from scanner into Nextcloud over FTP.

Components

permcorrect.py : main program file to be ran as a service

config.yml : configuration paramaters for root folder location, log file location and desired owner/permission settings.
Note: permcorrect.py expects config.yml to be located in /lib/systemd/system/permcorrect.d/. "with open(..." will need to be manually updated if located elsewhere

permcorrect.service : systemd unit file installed by default into /lib/systemd/system

Installation: Systemd Service (recommended)

1. Clone repo to local system
2. Create /lib/systemd/system/permcorrect.d/
3. Update config.yml with desired paramaters
4. Move config.yml and permcorrect.py into permcorrect.d
5. Move permcorrect.service into /lib/systemd/system/
6. Run sudo systemctl daemon-reload
7. Run sudo systemctl start permcorrect.service
8. Enable service auto-start by running sudo systemctl enable permcorrect.service
9. Place an incorrect file within the monitored folder and confirm it is corrected within the wait period (default 5 seconds) as well as an entry created in configured log file location (default /var/log/permcorrect.log)

Installation: Cronjob

1. Clone repo to local system
2. Modify permcorrect.py as follows:
   • Remove Import systemd.daemon
