Please excuse me, but what exactly is MacPorts? How does it work? Is it really what I want to use? I found Mac Ports through looking at another program called Jailkit, and there was another website (the predecessor to MacPorts?) called DarwinPorts. Unfortunately, the main page of MacPorts does not have a simplified "This is what this is, this is what it does" type of introduction, and I find that to be enormously helpful in putting myself in the right mindset for what I am dealing with. Essentially what I'm trying to do is create an automated updater on a client computer that logs into the server using sftp and downloads updated files from a certain directory. The server is Mac OS X 10.4.9, and I would like the account that the updater uses to be chrooted to the download directory. Based on my research so far, chroot is broken with the OpenSSH server unless you install a patch or do other stuff, which I'm trying to minimize messing with the current settings of the server and was really hoping to just have a restricted user or group account. The jailkit program seemed like a simple solution, but to use it on the Mac, I would have to install MacPorts? Or is this just introducing another mess for myself? I'm not even positive at this point if that's what I really want to use... Thank you. Diane
