Limit FTP access to a certain folder for all customers

I want to limit the FTP access for all customers to just the folder web/uploaded, how do you suggest I do this?

 

I did that and restarted the FTP service but it didn't affect anything when I log in..

 

Include /etc/proftpd/modules.conf

UseIPv6 off

ServerName "Debian"
ServerType standalone
DeferWelcome off

MultilineRFC2228 on
DefaultServer on
ShowSymlinks on

TimeoutNoTransfer 600
TimeoutStalled 600
TimeoutIdle 1200

DisplayLogin welcome.msg
DisplayFirstChdir .message
ListOptions "-l"

DenyFilter \*.*/

Port 21

MaxInstances 30

User proftpd
Group nogroup

Umask 022 022
AllowOverwrite on

TransferLog /var/log/proftpd/xferlog
SystemLog /var/log/proftpd/proftpd.log

<IfModule mod_tls.c>
TLSEngine off
</IfModule>

<IfModule mod_quota.c>
QuotaEngine on
</IfModule>

<IfModule mod_ratio.c>
Ratios on
</IfModule>

<IfModule mod_delay.c>
DelayEngine on
</IfModule>

<IfModule mod_ctrls.c>
ControlsEngine on
ControlsMaxClients 2
ControlsLog /var/log/proftpd/controls.log
ControlsInterval 5
ControlsSocket /var/run/proftpd/proftpd.sock
</IfModule>

<IfModule mod_ctrls_admin.c>
AdminControlsEngine on
</IfModule>

DefaultRoot ~
IdentLookups off
ServerIdent on "FTP Server ready."

Include /etc/proftpd_ispconfig.conf

 

I did that but it didn't help so I changed it back.

 

as I remember, the default root is also in Include /etc/proftpd_ispconfig.conf for each IP, so you need to edit this file also.

 

That file resets itself when I restart the FTP service..
