Explaination:

ServerName:   Name anything you wanna call your server

ServerType :   standalone/inetd 

inetd :  Doesn't support many connections but good for small use. It also minimize the resources being used by proftpd daemon.

standalone: more cpu resource usage . Good for large connection and ftp usage.

DefaultRoot: By default it's set to (~) /home/user/ . It's the directory which'll become your ftp root.

Lets try connecting to our ftp server.

One done configuring your /etc/proftpd/proftpd.conf file,  save it and close it.

Run proftpd server : proftpd  stop/start/status

root@dragonaider:/home/sahilsk# /etc/init.d/proftpd stop
 * Stopping ftp server proftpd    


now, lets confirm it.
open filezilla and enter following parameter:
host: localhost
username: your usernam on your system
password: your usual  password on your system

Don't get confused with "Remote site: /" . '/' is not my root folder, but it's folder which i set as root in proftpd.conf  "DefaultRoot" option
