On my FTP server, I have a folder called "upload". What I want is for people to be able to see that the folder is there, and to be able to upload stuff into it, but not see the files that are inside it. Is there a way to accomplish this? Currently, they can't see the upload folder. This is my proftpd.conf:
ServerName "ProFTPD Default Installation"
UserAlias anonymous ftp
<Limit LIST NLST>
