10.2 FTP Server

File Transfer Protocol (FTP) is a TCP protocol for uploading and downloading files between
computers. FTP works on a client/server model. The server component is called an FTP daemon.
It constantly listens for FTP requests from remote clients. When a request is received, it manages
the login and sets up the connection. For the duration of the session it executes any of commands
sent by the FTP client.
Access to an FTP server can be managed in two ways:

z z Anonymous
z z Authenticated
In the Anonymous mode, remote clients can access the FTP server by using the default user
account called “anonymous” or “ftp” and transfer an email address as the password.

!

Caution In the Authenticated mode a user must have an account and a password.
User access to the FTP server directories and files is dependent on the permissions defined for
the account used at login. As a general rule, the FTP daemon will hide the root directory of the
FTP server and change it to the FTP Home directory. This hides the rest of the file system from
remote sessions.
