Help with Virtual FTP
 

I have a server with 4 IP addresses. I'v been able to setup
Apache Virtual Host ok, with multiple document roots being
served depending on which IP address is specified in the
browser.

But what about FTP? I want each virtual domain ( domains
defined in Virtual Host apache ) to have their own FTP
logins, and that each one cannot see each other's files.
Where do I start?

Right now, I'm using vsftp.

Regards,

Dave
