Application Ten applications are preset. For custom
applications, enter the name of your application in one of
the available fields.
The preset applications are among the most widely used
Internet applications. They include the following:
FTP (File Transfer Protocol) - A protocol used to transfer
files over a TCP/IP network (Internet, UNIX, etc.). For
example, after developing the HTML pages for a website
on a local machine, they are typically uploaded to the web
server using FTP.
Telnet - A terminal emulation protocol commonly used on
Internet and TCP/IP-based networks. It allows a user at a
terminal or computer to log onto a remote device and run
a program.
SMTP (Simple Mail Transfer Protocol) - The standard e-
mail protocol on the Internet. It is a TCP/IP protocol that
defines the message format and the message transfer
agent (MTA), which stores and forwards the mail.
DNS (Domain Name System) - The way that Internet
domain names are located and translated into IP addresses.
A domain name is a meaningful and easy-to-remember
“handle” for an Internet address.
TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP
FTP protocol that has no directory or password capability.
Finger - A UNIX command widely used on the Internet
to find out information about a particular user, such as a
telephone number, whether the user is currently logged
on, and the last time the user was logged on. The person
being “fingered” must have placed his or her profile on
the system in order for the information to be available.
