Operating Systems HP-UX ftp download problem

Apparently I had your question backwards. It now seems that you want to know how to prevent a user from deleting files that do not belong to that user. This has nothing to do with FTP. It has to do with the permissions that are set for the files. If any random user is able to delete a file owned by root it is because the file permissions are set to allow that.

Here is an example of a file listing for a file owned by "anyuser" that can be written to and/or deleted by everyone on the system:

-rw-rw-rw- 2 anyuser mygrp 96 Apr 12 10:22 filename

If I wanted to prevent other users from being able to delete this file I would issue the following command:

chmod 644 filename

After that the file listing would look like this:

-rw-r--r-- 2 anyuser mygrp 96 Apr 12 10:22 filename

Other users are now allowed to read the file, but cannot delete it or change it.

RishiPahuja is correct, file deletion is controlled by write permission to the directory that contains the link. See Unix File Permissions
