I have a new client, they are a signage firm. They are looking to offer their client-base ftp functionality to upload large files. I'm looking for an open source (preferably PHP) solution that would allow for:
- Client specific username/password
- Client can only view files/directories associated to their credentials
- Ability to control what file types and size are uploaded
- 100% web interface for both user and admin side
The site resides on a Linux server.
