Hello

We're using Ubuntu and vsftpd.

This machine serves as an Apache web server and an FTP server.

We would like to create an FTP folder where one user account has read&write permissions but not delete (Account "A"), and another account which has full control permissions for the folder (Account "B").

Account A is supposed to send files to this folder on a daily basis. We want this folder to be like a drop box for this user.

We want a large number of people to use this account so we won't have to set up numerous user accounts.

If we set "Write" only permission for this user, he will not be able to view what he has uploaded. We want him to be able to view the folder's contents.

If we set his rights to "Read&Write" he will be able to delete all the files in the folder, including other people's.

How can we deny delete from this user?

Thanks very much,
Gant.
