Samba is a great tool for sharing data on your LAN and Jack Wallen shows you how to use it to share a guest folder that doesn't require a user account on your system.

Need to lock down that Linux server so certain remote users can only access a specific directory and only for file upload and download purposes? Jack Wallen shows you how.
