On one of my servers, I have ProFTPD installed in Debian 7. I need special permission only for 2 specific folders. These are:
append - user must be able to append data to an existing file
rename - user must not be able to rename file if same exists
How can I do this?
As far as I understand there are no special operations like append and rename that you can configure.
An append effectively is opening a file and then writing it with a different content (even if you only add to the file). You will need to have write privileges on that file.
A rename effectively is moving a file from an old location to another new location. You will need to have write privileges in that directory
