I'm currently trying to set up a FTP site which only allows users to upload files using vsftpd in archlinux. After some googling I didn't find any satisfactory solutions.
The current partial solution is as follows. In vsftpd.conf, I set download_enabled to FALSE and write_enable to TRUE. I created a user in linux that is only used for this ftp site.
Specifically, my problem is:
Are there any ways to differentiate between permission for uploading files and permission for deleting files, and accordingly, enabling one while disabling the other?
The relevant softwares, vsftpd and archlinux, are up to date.
