Chapter 1
1. Overview of the Internet Gateway
This chapter presents an overview of how to connect to the Internet with a WebFORCE
Internet Gateway. It summarizes the basic steps to setting up the server, lists the parts
required, and indicates the information you may need to exchange with your Internet
service provider (ISP) before you connect to the Internet.
About the WebFORCE Internet Gateway
The WebFORCE Internet Gateway connects hosts on a local area network (LAN) to the
Internet, a network cooperative that allows millions of network users to publish and
exchange information easily. In addition to providing access to the Internet, the
WebFORCE Internet Gateway may act as an applications server, providing Internet mail,
news, and other services to client hosts on the LAN.
Hosts on the Internet operate by a common standard, formally known as Transport
Control Protocol, Internet Protocol (TCP/IP). This means that the Internet Gateway
system and its clients, such as personal computers and workstations, must also run the
TCP/IP stack (so called because of its layered, or stacked, software architecture). The
Gateway and its clients must also be assigned an Internet address (IP address), which
uniquely identifies each host on the Internet.
A specialized private or public agency, known as an Internet service provider (ISP),
handles membership for new Internet members. An ISP assists with obtaining a
registered network address from the Network Information Center, which maintains the
Internet database. It also issues blocks of Internet addresses for clients in the new
network and may recommend addressing and routing schemes.
Because direct connections to the Internet backbone are limited, all hosts must connect to
the Internet through an ISP. The WebFORCE Internet Gateway is designed to help you
do this (see Figure 1-1). The WebFORCE Internet Gateway and the ISP can be connected,
for example, by a standard telephone line and modem, an ISDN line, or a T1 line.

Before You Connect to the Internet
3
Before You Connect to the Internet
Before you start, you may wish to contact your Internet service provider (ISP). Your ISP
will need some basic information about your network and WebFORCE Internet Gateway
server, and should provide you with information that you need to configure the
WebFORCE Internet Gateway server to communicate with the Internet.
Setting Up Your Internet Gateway
To set up your Silicon Graphics WebFORCE Internet Gateway server, perform the
following steps:
1. Unpack and assemble the server (described in the server owner’s guide).
2. If this is server does not have a graphics monitor directly attached to it, you can
attach a system console to the server using serial cables. The system console can be a
character (ASCII) terminal, an IBM compatible computer, a Macintosh computer, or
another workstation. (If the server does have a graphics monitor, refer to “Using
WebFORCE Internet Gateway From Your Web Browser”on page 22.)
3. Configure the server so that you can access it over your local network with a World
Wide Web browser (such as NetscapeM).
4. Use the Web browser to configure the server to connect to the Internet.
Parts of a WebFORCE Internet Gateway
WebFORCE Internet Gateway ships with the following components:
•A Silicon Graphics server, including documentation (the owner’s guide plus online
reference pages)
•A serial cable
•WebFORCE Internet Gateway software, installed on the server’s system disk and
provided on CD-ROM

Information Your ISP May Require
Table 1-1 describes some of the general information your ISP may require.
Table 1-1 General Information Your ISP May Require
Type of Information Value
Name of gateway
machine (server)
Whatever you decide to name the machine, for example, the name of
your company or organization. Typically, it is a good idea to keep the
name short, easy to type, and easy to remember.
Type of machine Server type, for example Silicon Graphics Origin 200 server.
Type operating system IRIX (UNIX).
Ethernet address Unique for each system on a network; the Ethernet address of your
server is the same as the serial number of the machine. Both are
imprinted on the rear of the machine and printed on the shipping
label for the server. One example is 08:00:69:08:19:24. You can also
find the Ethernet address of the system once it is booted by entering
the following command at a shell prompt: nvram eaddr.
Maximum baud rate for
your modem (if you are
using a modem)
The maximum speed at which your modem can communicate with
the ISP, often 14.4 Kbaud or 28.8 Kbaud.

Chapter 1: Overview of the Internet Gateway
Information Your ISP May Provide
Table 1-2 shows some of the information your ISP may provide.
Table 1-2 Information Your ISP May Provide
Type of Information Value
Account name The name of the account you will use to access the ISP. This is
similar to an IRIX (UNIX) login account name; it might be an
abbreviated name of your company or organization, or it could
be some other series of letters or numbers.
Account password The password your software uses to access the account you have
with your ISP.
Phone number If you are using ISDN or a dial-up (modem) connection, this is
the phone number the server calls to connect to your ISP.
Baud rate for your modem If you are using a modem, the maximum baud rate at which the
ISP accepts data from your modem.
IP address of your gateway Your ISP may assign an Internet protocol (IP) address to your
gateway machine. This address number is how other systems on
both the Internet and on your local area network (LAN) identify
your server. The address is a series of numbers separated by
decimal points, for example 151.166.96.36.
IP address of a name server This is the IP address of another machine, probably located at the
ISP, that provides Internet name services for you. When your
server needs to locate another system on the Internet, it contacts
this machine. Conversely, when other systems try to locate your
server, they contact this machine.
Domain name This is the name of the Internet domain in which your server
resides. It can be the name of your company (for example,
toyparts.com), the name of your organization (freestuff.org), or
some part of your geographic location (for example,
janedoe.sf.ca.us, which would indicate a server located in San
Francisco, California, in the United States of America.)

Chapter 2
2. Connecting the Cables
This chapter describes how to connect a serial console to the server. Possible types of
serial consoles include
•an IBM compatible personal computer, described in “Connecting an IBM
Compatible Personal Computer As the Serial Console”on page 8
•a Macintosh computer, described in “Connecting a Macintosh Computer as the
Serial Console”on page 9
In addition, you can use the following as system consoles for your server:
•a character (ASCII) display terminal
•another Silicon Graphics server (such as Onyx or Origin)
•another manufacturer’s workstation
Setting Up the Server
Follow the instructions in the Silicon Graphics server owner’s guide to unpack and set
up the server. Install any memory, peripheral, or other options shipped with the system,
and connect the power and network cables. Then do the following:
•If you are using a character (ASCII) terminal or another Silicon Graphics
workstation as the serial console for your server, follow the instructions in the
server owner’s guide to set up the server and the terminal, then turn to Chapter 3,
“Setting Up the Terminal Emulator and Starting WebFORCE Internet Gateway.”
•If you are using an IBM compatible computer as the serial console, proceed with the
next section, “Connecting an IBM Compatible Personal Computer As the Serial
Console”on page 8.

Chapter 2: Connecting the Cables
•If you are using a Macintosh computer as the serial console, go to the section
“Connecting a Macintosh Computer as the Serial Console”on page 9.
•If you are using a workstation from a vendor other than Silicon Graphics as the
serial console, go to “Connecting Other Types of Workstations as the Serial
Console”on page 9.
Connecting an IBM Compatible Personal Computer As the Serial Console
Follow these steps to connect an IBM compatible personal computer (PC) to your server
as the serial console:
1. Locate the appropriate serial cable. Some servers ship with the serial cable to
connect to the PC-compatible computer. Otherwise contact your Silicon Graphics
sales representative, or locate a serial cable with the correct connectors for the
server’s serial port 1 and the PC’s COM1 or COM2 port.
2. Attach the PC’s COM1 or COM2 port to port 1 of the Silicon Graphics server.
■You can use either COM1 or COM2 on your personal computer.
■Make a note of which COM port you use. You will need this information later
when you configure the terminal emulator on the personal computer in
Chapter 3, “Setting Up the Terminal Emulator and Starting WebFORCE Internet
Gateway.”
You are now ready to configure your personal computer as a serial console for the server.
Turn to Chapter 3, “Setting Up the Terminal Emulator and Starting WebFORCE Internet
Gateway.”

Connecting a Macintosh Computer as the Serial Console

Connecting a Macintosh Computer as the Serial Console
Follow these steps to connect a Macintosh computer as the serial console for your server:
1. Locate the appropriate serial cable. Some servers ship with the serial cable to
connect to the Macintosh computer. Otherwise contact your Silicon Graphics sales
representative, or locate a serial cable with the correct connectors for the server’s
serial port 1 and a Macintosh serial port.
2. Attach the Silicon Graphics server’s serial port 1 to the Macintosh serial port with
the cable.
■Make a note of which serial port you use on your Macintosh computer. You will
need this information later when you configure the Macintosh as a serial
console for the server.
You are now ready to configure your Macintosh computer as a serial console for the
server. Turn to Chapter 3, “Setting Up the Terminal Emulator and Starting WebFORCE
Internet Gateway.”
Connecting Other Types of Workstations as the Serial Console
If you have a workstation that was not manufactured by Silicon Graphics, you can attach
it to your WebFORCE Internet Gateway server in much the same way that you would
attach a personal computer or Macintosh computer. Because of the different possible
serial port configurations of various workstations, this book cannot provide all possible
adapters. However, you can use the pin and signal descriptions in Table 2-1, below, to
obtain or create the necessary adapter cable.
The specific connector type and pin numbers of the connector vary, depending upon the
workstation you wish to connect. See your workstation documentation.
