The other day, a customer asked me to setup an FTP account for his clients to use in uploading files to his machine. And while the built-in file serving of Leopard is nice, it’s not made for this sort of thing. For instance, creating a “Sharing Only” user account will only allow AFP and SMB connections.
There are plenty of options and it makes it real easy to have a powerful file server. The app is free from the developer’s site, though donations are appreciated.
