How do you set up an FTP server using a NAS device?

Well you actually need to have an ftp server running somewhere. I dont know (although i doubt it does) if your NAS has an embedded FTP or SFTP server. If it dosent youll actuall have to have people connect to one of your servers/workstations that has FTP enabled.

First youll need to log in to your router's admin panel and forward port 21 to the server/workstation that will function as the ftp server.

Then set up the mount for the NAS device at large or one of the specific folders on it with sharepoints or something on the mac that will act as the ftp server.

Set up a user as a FTP only user. Youll probably want to make this user only have FTP access (you can google or consult other threads in these forums for this procedure).

In this users home folder make symlinks to the shares with the command line:



Then create the file /etc/ftpchroot which will contain a list of users that will be limited to thier home directory when using ftp. i would use a command line text editor to do this (pico, vi, emacs... choose your poison).
the file should simply be a list of user shortnames, 1 per line.

Thats the basics of it. You can get more complicated and might indeed need to set up permissions and what not properly (youll probably want to use ACLS so you dont have to constantly change permissions or login as another user to access files that have been uploaded)but that should get you started i think.
