NNTP
(Network News Transfer Protocol) The protocol used to connect to
Usenet groups on the Internet.
•
SNMP
(Simple Network Management Protocol) A widely used network
monitoring and control protocol. Data is passed from SNMP agents, which
are hardware and/or software processes reporting activity in each network
device (switch, router, bridge, etc.) to the workstation console used to over-
see the network. The agents return information contained in a MIB
(Management Information Base), which is a data structure that defines
what is obtainable from the device and what can be controlled (turned off,
on, etc.).
Enter the
number
of the internal port used by the server in the Int. Port col-
umn. Check with the Internet application software documentation for more
information.
Enter the IP address of the server that you want the Internet users to be able to
access. For information about finding the IP address, go to “Appendix D:
Finding the MAC Address and IP Address for Your Ethernet Adapter.”
You must check the
Enable
box to enable the applications you have defined.
To add a Customized Application using UPnP Forwarding:
1. Enter the
name
of the application in the appropriate Customized
Applications field.
2. Next to the name of the application, enter the
number
of the external port
used by the server in the Ext. Port column. Check with the Internet appli-
cation software documentation for more information.
3. On the same line, select
Protocol TCP
or
Protocol UDP
.
4. Enter
the
number
of the internal port used by the server in the Int. Port col-
umn. Check with the Internet application software documentation for more
information.
5. Enter the IP address of the server that you want the Internet users to be able
to access. For information about finding the IP address, go to “Appendix D:
Finding the MAC Address and IP Address for Your Ethernet Adapter.”
6. Check the
Enable
box to enable the services you have defined. UPnP
Forwarding will not function if the
Enable
button is left unchecked. This is
disabled (unchecked) by default.
The Preset Applications at the top of the list 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, web developers typically
upload the files to the web server using FTP. FTP includes functions to log
onto the network, list directories, and copy files. FTP operations can be per-
formed by typing commands at a command prompt or via an FTP utility
running under a graphical interface such as Windows. FTP transfers can
also be initiated from within a web browser by entering the URL preceded
by 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 proto-
col that has no directory or password capability.
•
Finger
A UNIX command widely used on the Internet to find out infor-
mation about a particular user, such as his or her 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. Fingering requires entering the
full user@domain address, for example, [email protected].
•
HTTP
(HyperText Transport Protocol) The communications protocol used
to connect to servers on the World Wide Web. Its primary function is to
establish a connection with a web server and transmit HTML pages to the
client web browser.
•
POP3
(Post Office Protocol 3) A standard mail server commonly used on
the Internet. It provides a message store that holds incoming e-mail until
users log on and download it. POP3 is a simple system with little selectivi-
ty. All pending messages and attachments are downloaded at the same time.
POP3 uses the SMTP messaging protocol. (SMTP may also need to be for-
warded.)
