 FTP SERVER CONFIGURATION IN REDHAT/CENT OS  

What Is Ftp?

The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files from a server to a client using the Client–server model on a computer network.

How FTP works

Step a: Client connects to server on port 21.
Step b: Server responds and ask for authentication.
Step c: Client decides weather to connect passively or actively and authenticate with credentials(user name password).
Step d: If it is an active connection, server opens port 20 for data transfer and gives ftp prompt after successful authentication.
Step e: Client call for file and server initiates file transfer.
Following picture shows a simple way of data transfer through ftp.Before setting up FTP server we have to clear our self about active and passive ftp

vsftpd (Very Secure File Transport Protocol Daemon) is a secure, fast FTP server for Unix/Linux systems. In this how-to 
article, let us see how to setup a basic FTP server using vsftpd on 
CentOS 6.5. This procedure will also work on all RHEL CentOS, Scientific
 Linux 6.x versions.

chroot_local_user=NO to chroot_local_user=YES.    This will permit local user as FTP account. If you add an user, it will be treated as a FTP account as well.
