Config Proftpd

Am instalat Proftpd pe mandriva 2007 si cand ma conectez la ftp  si dau back pe directorul radacina , vad structura de
directoare ale linux-ului.
Cum fac sa blochez sa ramana numai in directorul de pe ftp?

Fisierul arata de forma:

#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes reload proftpd after modifications.
#

# Includes DSO modules
Include /etc/proftpd.d/*.conf

# This is the directory where DSO modules resides

ModulePath /usr/lib/proftpd

# Allow only user root to load and unload modules, but allow everyone
# to see which modules have been loaded

ModuleControlsACLs insmod,rmmod allow user root
ModuleControlsACLs lsmod allow user *
