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

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.)

Before You Connect to the Internet

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)

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

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.

3. Setting Up the Terminal Emulator and

Starting WebFORCE Internet Gateway

This chapter provides a general overview of how to conﬁgure the terminal emulator software on your IBM compatible personal computer or Macintosh computer for use as a system console with the Internet Gateway server. It also describes the steps to start and begin to use WebFORCE Internet Gateway software.

Types of Terminal Emulators

To communicate with the Internet Gateway server through a Macintosh or PC, you need a terminal emulator. Many operating systems, such as Microsoft Windows, ship with a terminal emulator package (also known as modem or communications software). Some examples of terminal emulator software include the following:

• Term

• HyperTerm

• TERMINAL.EXE

• Bitcom

• Procomm

• ZTerm

• SITcomm

• Macterm

On UNIX based systems, two common utilities are cu and ct. The server owner’s guide provides basic instructions for using cu on a Silicon Graphics workstation to communicate with a server. The steps are similar for other UNIX based systems. Also, see the cu(1) and ct(1) reference pages.

Terminal type Any of the following:

DEC VT100, VT102, Wyse 60, ANSI, or dumb

Flow control None or XON/XOFF

To conﬁgure your terminal emulator, follow these general steps:

1. Power on your IBM compatible or Macintosh computer.

2. When the system has booted, locate and start the terminal emulator.

3. Adjust the settings for your terminal emulator as indicated in Table 3-1.

■ Be sure the terminal emulator software is conﬁgured to use the serial port on

your computer to which you attached the serial cable.

■ Note which terminal type (such as VT100 or ANSI) you choose to emulate. You

will need this information when you log in to the server.

■ Other settings, such as upload and download protocol, initialization strings,

and ﬁle transfer settings do not matter for this procedure. You can leave them set to their defaults.

Accessing the Server

Follow these steps to access the server:

1. Turn on the server, if you have not done so already.

2. Press Enter once or twice on your computer or terminal. You should see a

power-on diagnostics message, followed by a menu similar to the following:

Running power-on diagnostics... System Maintenance Menu

1) Start System

2) Install Software

3) Run Diagnostics

4) Recover System

5) Enter Command Monitor

Option?

■ If you do not see the System Maintenance Menu, and nothing happens when

you press Enter, make sure the cables are correctly attached. The 8-pin connector on the long serial cable must be in port 1 of the server.

■ Make sure you have conﬁgured the terminal emulator to use the correct serial

port on your computer.

■ If you are using a character (ASCII) terminal, make sure the baud rate setting is

correct (9600 baud). Also, if the terminal has more than one connector on the back, make sure you are using the correct one. It should be the connector marked “Data,” “Modem,” or something similar. Make sure the terminal is conﬁgured to use that connector.

■ If you see strange characters on your screen (such as xx‘‘x‘) when you press

the return key, you may not have set the baud rate correctly in your terminal emulator or character terminal. It must be set to 9600 baud.

Chapter 3: Setting Up the Terminal Emulator and Starting WebFORCE Internet Gateway

3. Type 1 and press Enter.

■ The server starts booting IRIX.

■ You should see messages similar to the following:

Starting up the system... IRIX Release 6.5 IP22 Version 02111257 System V

System is coming up... IRIS login:

Once you see the IRIS login: prompt, you are ready to log in to the server and initialize WebFORCE Internet Gateway.

Logging In to the Server and Initializing WebFORCE Internet Gateway

The next step in installing WebFORCE Internet Gateway is to log in to the server and run the start-gateway program, which prompts you for some information that is necessary to conﬁgure your Internet gateway.

Take a moment to ﬁll out this checklist so that you have ready all the information needed by start-gateway. Fill in the middle column of values in Table 3-2 below.

What It Is and Why It Is Needed

The name can be any number or alphabetic character in the 7-bit ASCII character set, and many non-alphabetic characters. Spaces, control characters, and characters used in internet addresses (such as periods, @ signs, and exclamation points) should not be used in the hostname.

Example: donut-7

Your ISP may already have provided you with a domain name. If you have not yet contacted an ISP and obtained a domain name, you can pick any domain name you want for the time being, though you may have to change it later.

Example: freestuff.org

Example: santa-cruz.ca.us

Table 3-2 (continued) Checklist of Information Needed to Initialize the Gateway Server

Information Value For Your Internet

Gateway Server

Internet address (or primary internet address)

What It Is and Why It Is Needed

This is the Internet address (also known as an IP address) of your gateway server. Your ISP provides an IP address for your server. If you have not yet obtained an IP address, you can use the default test address that is assigned to the machine when it leaves the factory.

See “Glossary” for a description of IP addresses.

Example: 151.166.96.36

Example: 192.0.2.1 (default test address)

Netmask The netmask speciﬁes how much of the

address to reserve for subdividing networks into subnetworks. The mask includes the network part of the local address and the subnet part, which is taken from the host ﬁeld of the address. The mask can be speciﬁed as a single hexadecimal number with a leading 0x, with a dot-notation Internet address, or with a pseudo-network name listed in the network table networks(4). The mask contains 1’s for the bit positions in the 32-bit address that are to be used for the network and subnet parts, and 0’s for the host part. The mask should contain at least the standard network portion, and the subnet ﬁeld should be contiguous with the network portion.

Logging In to the Server and Initializing WebFORCE Internet Gateway

Follow these steps to log in to the server and initialize WebFORCE Internet Gateway:

1. At the IRIS login: prompt, type root and press Enter.

■ You see various boot-up messages followed by a login prompt similar to the

following:

■ If you set the terminal type in your emulator software to VT100, press Enter.

■ If you set the terminal type in your emulator software to another type of

terminal, enter the name of the terminal type (for example, vt102 or ansi) and press Enter. Be sure to use lowercase letters when entering the terminal type. Like all UNIX operating systems, IRIX is case sensitive, so VT102 is not the same as vt102.

You should now see the root shell prompt, IRIS 1#.

You can now do one of the following:

■ Leave your terminal emulator session running and leave the serial cables

connected from your client system (system console) to the gateway server. You may wish to do this at least until you are sure the server is running and conﬁgured properly.

■ Quit the terminal emulator session and disconnect the serial cables between

your client system (system console) and the gateway server. This is appropriate when you are sure your network and the gateway server are conﬁgured properly.

■ If you are using a character (ASCII) terminal, you can leave it attached to the

server.

Chapter 3: Setting Up the Terminal Emulator and Starting WebFORCE Internet Gateway

2. To start WebFORCE Internet Gateway, type start-gateway and press Enter. You

see the following:

Welcome to your Silicon Graphics WebFORCE Internet Gateway server! There are a few simple steps to connect your server to the Internet:

First, use this terminal window to configure your server to communicate with your local network by means of an IP connection. Currently, you are using a serial cable connection to communicate between your server and a terminal device (such as a VT-100 terminal or a PC-compatible, Macintosh, or Indy computer running terminal emulation software), but the serial connection will be replaced.

After you configure your server using this terminal window, you will configure your server to communicate with the Internet. For this step, you will use a Web browser on your PC-compatible, Macintosh or Indy computer. Your computer will communicate with your server through an Ethernet cable.

The current configuration of your server is: Hostname: IRIS

Domain name: IP Address: 192.0.2.1 Netmask: 0xffffff00

You must change these factory settings to connect your server to the Internet. Most of the information that you need to make these changes is supplied by your Internet service provider (ISP). Make sure you have the appropriate information from your ISP, and follow the steps below.

A hostname uniquely identifies your Silicon Graphics Internet Gateway server. By convention, hostnames contain only lowercase letters.

Enter a hostname for this server: [IRIS]

■ Enter the hostname you wish to assign to the server at the prompt Enter a

hostname for this server: [IRIS]

and press Enter.

Logging In to the Server and Initializing WebFORCE Internet Gateway

3. You are prompted to enter a domain name for your gateway server:

Each organization on the Internet is known by its domain name. Domain names usually contain two (or three) segments, separated by periods. Your ISP assigns domain names. (Example: aspen.com)

Enter the Domainname for this server: [ ]

Type in the name of the domain in which your gateway server resides. For example:

freestuff.org or acme.com and press Enter.

4. You are prompted for the Internet address of the gateway server:

The primary network interface connects the server to your local area network. Use an IP address that you obtained from your ISP as the IP address for the primary network interface. (Example:

196.45.23.4) Enter the IP Address of the primary network interface: [192.0.2.1]

Enter the Internet address that your ISP provided for your gateway server and press

Enter.

Note: You cannot connect to either the Internet or your LAN using the default IP

address of 192.0.2.1. This is a temporary address that is used on all Silicon Graphics computers when they ship from the factory. You must change this address.

5. You are prompted for the netmask of your gateway server:

The netmask is used in conjunction with the IP address. In most cases, you can use the default netmask.

Enter netmask for this interface: [0xffffff00]

Enter the netmask desired and press Enter, or just press Enter to use the default netmask of 0xffffff00.

Chapter 3: Setting Up the Terminal Emulator and Starting WebFORCE Internet Gateway

6. You are prompted to verify the information you just entered:

Verify Configuration. You have entered: Hostname: mymachine Domainname: acme.com IP Address: 151.166.96.36 Netmask: 0xffffff00

Is this correct? [y/n]

■ If the information is correct, type y and press Enter.

■ If you wish to start over and change any of the information, type n and press

Enter. The procedure begins again from step 2.

7. When you are satisﬁed with the gateway server conﬁguration (you enter y in the

preceding step), you are prompted to reboot the server:

You now need to reboot your server to put your changes in effect. After your server reboots, complete these steps:

1. Open a Web browser on your computer

2. Open the URL “http://151.166.96.36:2077/” in the browser

3. Select “Setup Tasks” on the WebFORCE Internet Gateway Web page to continue connecting to the internet.

After your server reboots, you can close this terminal window on your terminal (or personal computer) window.

Reboot server now? [y|n]

To reboot the server, type y and press Enter. This not only reboots the server, but it causes the server to reconﬁgure itself with the new information you have provided in the preceding steps.

8. Once the server has rebooted, you see the following in your terminal emulator window or screen:

mymachine login:

Instead of mymachine, you see whatever name you assigned to the gateway server.

9. Log in to the server again. At the prompt mymachine login: type root and press

Enter.

Logging In to the Server and Initializing WebFORCE Internet Gateway

10. When you see the root shell prompt, mymachine 1#, you are ready to test the

network connection between the server and other machines on your LAN.

■ Verify that the system on which you will use your Web browser can receive

network packets from the gateway server. Enter /usr/etc/ping ip_address. Replace ip_address with the IP address of the system on which you will run the Web browser. You should see output similar to the following:

PING 151.166.96.20 (151.166.96.20): 56 data bytes 64 bytes from 151.166.96.20: icmp_seq=0 ttl=255 time=1 ms 64 bytes from 151.166.96.20: icmp_seq=1 ttl=255 time=1 ms 64 bytes from 151.166.96.20: icmp_seq=2 ttl=255 time=1 ms 64 bytes from 151.166.96.20: icmp_seq=3 ttl=255 time=1 ms 64 bytes from 151.166.96.20: icmp_seq=4 ttl=255 time=1 ms

After several lines of output from ping, press Ctrl+C to interrupt the program. You should see lines similar to the following:

----151.166.96.20 PING Statistics---5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max = 1/1/1 ms

This indicates a properly-functioning connection between your gateway server and the other machine on your network.

■ If there is a network problem, the ping command displays only the following

line:

PING 151.166.96.20 (151.166.96.20): 56 data bytes

If this happens, press Ctrl+C to interrupt the program. You see lines similar to the following:

----151.166.96.20 PING Statistics---5 packets transmitted, 0 packets received, 100% packet loss

If this happens, verify that both machines are attached to the network and that the cables are connected securely. Also, try using the ping command to check the connection to other machines on the network and compare the results. If you are connecting the two machines directly (without using a hub or concentrator), make sure the cable is properly wired.

If there are no network problems, you are now ﬁnished initializing WebFORCE Internet Gateway. You are ready to ﬁnish conﬁguring your Internet Gateway server using a Web browser.

To ﬁnish conﬁguring WebFORCE Internet Gateway, use a Web browser (such as Netscape) on a workstation on your LAN. Access the Internet Gateway server with the Web browser, and ﬁll out a series of forms that complete the conﬁguration process.

Follow these steps:

1. Be sure the server is running.

■ Use the chkconﬁg command to turn on the Internet Gateway:

chkconfig webface on

■ Start the Internet Gateway Web server:

/etc/init.d/webface start

2. Start your Web browser (for example, Netscape) from a computer or workstation on your LAN.

■ You can run the Web browser from any computer or workstation that is on the

same LAN as the Internet Gateway server.

■ For best results, use Netscape Navigator 2.0 or later. You can use other

browsers, but they must support HTML frames and ﬁll-out forms.

3. Open the following uniform resource locator (URL):

http://server_ip_address:2077/

■ In this URL, server_ip_address is the IP address you assigned to the Internet

Gateway server. For example:

http://151.166.96.36:2077/

If there is no root password, you will be required to create one. You are then prompted to enter an administrative account user ID and create a password for the administrative account.

Then you see the Internet Gateway home page shown in Figure 3-1 in your browser window.

■ If you do not see the screen as shown in Figure 3-1, verify that you can open

other URLs on your LAN with your Web browser.

■ If you cannot open other URLs on your LAN, there may be a conﬁguration

problem with your browser. In particular, if your browser is capable of using proxies, make sure they are turned off. (In Netscape 4.x, proxies are set in the Edit/Preferences/Advanced menu.)

4. Click the Setup Tools icon shown in Figure 3-2 to ﬁnish the WebFORCE Internet Gateway conﬁguration. You are then prompted for the administrative user ID and password that you have chosen.

Glossary

datagram

Data sent over a network. A datagram contains not only user data, but also all the necessary header information for the data to reach its intended destination.

ﬁrewall

A computer or router that blocks certain types of network datagrams from passing between networks. One example of a ﬁrewall is a computer that routes data between a local area network and the Internet, but disallows certain types of direct access from the Internet to computers on the local area network. See also gateway.

gateway

A computer or router through which data passes between networks. One example of a gateway is a computer located between a local area network (LAN) and the Internet. See also ﬁrewall.

intranet

An internal or limited network that uses the basic technologies of the Internet, including Transmission Control Protocol/Internet Protocol (TCP/IP) and World Wide Web servers and browsers. See also local area network, internet, and Internet.

Internet

The world-wide network of computers communicating via Internet protocol (IP) datagrams. See also internet.

Internet service provider

Also ISP. An organization or individual who provides the network access for you to connect to the Internet. The ISP relays data from your gateway computer or router to the Internet and vice-versa.

Internet Protocol (IP)

The communication protocol used in combination with TCP to form the standard means (TCP/IP) of communication on the Internet.

Glossary

IP address

A number that identiﬁes a computer on a TCP/IP network. An IP address is made up of four numbers separated by decimal points, such as 192.26.4.89. Each individual number can be between 0 and 255 (with some exceptions, for example, for reserved IP addresses).

local area network (LAN)

A network of computers local to an organization, typically high speed (such as 10 Base-T Ethernet, FDDI, Token Ring, and so forth), and typically in close proximity. See also intranet.

system console

A character (ASCII) terminal or other computer that is used to communicate with a workstation or server to set up the system, perform system maintenance, operate the system in PROM mode, and display system error messages. See also system console port.

system console port

The serial port to which a system console is attached. On Silicon Graphics workstations and servers, this is the ﬁrst serial port (port 1).

TCP/IP

Transmission control protocol used with the internet protocol. See transmission control protocol.

transmission control protocol

A networking standard, typically used with the Internet Protocol (IP) standard. It forms the basis of an internet as well as the Internet. See also internet protocol.

wide area network (WAN)

A network of computers spanning a wider geographic area than a local area network, and typically using communication technologies designed for longer distances, such as microwave relay and leased (telephone) lines.
