i'm running linux on my VPS server. using WEBppliance Pro3.5.20
I am trying to set up ftp accts for my website administrators, using the control panel i can set up the user accounts but it will not allow me to give them certain permissions like ex. user 1 only allowed access to /var/www/html/staff and nothing below that
there has to be a way to do this through ssl I have FULL root access to my box i tried this command
[root@deep ] /# useradd -d /home/var/www/html/staff/ -s /dev/null ftpadmin > /dev/null 2>&1
[root@deep ] /# passwd ftpadmin
root@deep ] /# vi /etc/shells
/bin/bash
/bin/sh
/bin/ash
/bin/bsh
/bin/tcsh
/bin/csh
/dev/null
root@deep ] /# vi /etc/passwd
ftpadmin:x:502:502::/home/var/www/html/staff/./ftpadmin/:/dev/null
this totaly messed up my control panel

I did a restore of my server and its back to normal. however I'm still not sure how to add a user to my ftp server with permissions "only to access a certain directory"
pls help
