Step1. Install ProFTPd:

apt-get install proftpd-basic

During installation you can choose to install as an inetd service,or a standalone server.  You will choose to install as Standalone  server.

Step2. Copy and rename the original configuration file for backup:

cp /etc/proftpd/proftpd.conf /etc/proftpd/proftpd.conf.bak

Step3. Edit the proftpd.conf file:

nano /etc/proftpd/proftpd.conf

And now change the following:

ServerName “ftp.debian-tutorials.com”

Uncomment the line to restrict users to their home directory:

DefaultRoot ~

Step4. Restart proftpd daemon:

/etc/init.d/proftpd restart

Now you can connect on your ftp server using a ftp client and using your system users for authentification.
Enjoy!
