Yesterday I downloaded and installed the TKL File Server appliance. My plans are to use it solely as an FTP server. I have created a user named abc (for example). I am successfully able to log into the server from Filezilla for example and directly into the abc user home directory without issue. My question is, how can I prevent the abc user from navigating the tree above his home directory (ex. /, /home, etc.)? I have been researching this for a couple of days, and so far, nothing that I have tried has helped. I guess it is obvious, but I will admit that I haven't used Linux/Unix in quite some time.
