I'm having trouble with file permissions. I created a new user and I'm able to use ftp with that new user, but when the new user tries to save a file it says 550 Permission Denied. The directory I tried to write to has ownership sample:sample, so I tried:
pw usermod newuser -G sample
But I'm still getting the Permission Denied error.
Any help would be greatly appreciated, and be gentle ... I'm not very good at Linux.
