Ubuntu – Limit ftp users to only certain directories in Ubuntu

file-permissionsftppermissionsUbuntu

There are several questions around limiting ftp users to certain directories. However, most of them refer to vsftpd, which I don't think I have installed on my system. I'm running Ubuntu 9.04. How can I tell what ftp service I have installed, and then limit certain users to only the /home/ftpuser directory instead of having full access to the file system?

I think I can add them to a separate group and give that group access to the proper directories, but then do I have to remove that groups permissions from all other directories? It seems like there should be an easy way like setting the chroot_local_user value in the /etc/vsftpd/vsftpd.conf file, but that doesn't exist on my system.

Update

Here are the results of: dpkg --list |grep -i ftp:

ii curl 7.18.2-8ubuntu4.1 Get a file from an HTTP, HTTPS or FTP server

I can connect to this servier using sftp but there are no ftp servers installed. Do I have to install one?

I'd recommend using proftpd with Ubuntu.... I follwed these steps recently and it worked ver y well....

Here's quick install steps: 

sudo apt-get install proftpd

# Add this line in /etc/shells file (sudo gedit /etc/shells to open the file)
/bin/false

cd /home
sudo mkdir FTP-shared
sudo useradd userftp -p your_password -d /home/FTP-shared -s /bin/false
sudo passwd userftp
cd /home
sudo chmod 755 FTP-shared

and edit your proftpd.conf file like that if it fit to your need 

sudo gedit /etc/proftpd.conf
or
sudo gedit /etc/proftpd/proftpd.conf

sudo /etc/init.d/proftpd start

These steps are from this very helpful thread on ubuntuforums.org
