File Transfer Protocol (FTP)

File Transfer Protocol (FTP) is a standard Internet protocol. It provides a simple way to exchange files between computers on the Internet.

With FTP a user may use a simple command line interface (for example the Windows MS-DOS Prompt window) or use a program that offers a graphical user interface. A standard Web browser can also make FTP requests.

There are two types of FTP modes: active and passive. The difference between the two FTP modes is how the data transfer is set up. With active FTP the server initiates the connection between the client and the server, with passive FTP the client makes all initiations.

Some FTP clients only support one of the types; some supports both and are able to automatically select which one to use in a specific situation.

Active FTP may imply security risks. Users using active FTP can be deluded to connect to a web site containing a Java applet that connects to a FTP server with a request to open up a specific port on the inside, exposing a hole through the firewall. The Java application installed on the users computer may then be used to delete and copy files or to plant a virus.

To be able to transfer file with FTP from your local network you have to enable support for FTP in the security profile you run. Click here for instructions.
