Banyan TCP/IP Guide
Chapter 1 - Installing Banyan TCP/IP Options
The Banyan TCP/IP options enable VINES servers to participate in networks of computers that use Transmission Control Protocol/Internet Protocol (TCP/IP) to communicate. Computers that use these protocols to communicate are often referred to as hosts and gateways.
A host is any system that implements IP, and that does not forward IP packets to other hosts.
A gateway forwards a packet that originates from a host or another gateway to its destination.
Some computers can act as hosts and gateways at the same time.
This chapter provides information you should know before you configure servers for TCP/IP communications. Topics discussed are as follows:

Banyan TCP/IP Routing Option
The Banyan TCP/IP Routing option enables servers to route TCP/IP traffic traveling between foreign hosts. A host is foreign when it does not use VINES protocols to communicate. Examples of foreign hosts include minicomputers or other computers that are not running VINES software.
The Banyan TCP/IP Routing option also allows VINES servers to route TCP/IP traffic to a VINES workstation running PC/TCP software. PC/TCP is a product from FTP Software, Inc., that allows VINES workstations to send and receive IP traffic. Traffic received can originate either from a foreign host or from another PC/TCP workstation.
Figure 1-1 shows a server with the Routing option. The server routes TCP/IP traffic between the two foreign hosts.
For details on how the TCP/IP Routing option works, see Chapter 2.
Banyan TCP/IP Server-to-Server Option
Servers equipped with the Banyan TCP/IP Server-to-Server option can exchange VINES packets through foreign host gateways, which are foreign hosts that perform IP routing functions. VINES packets contain data that originates from VINES applications, such as mail and the StreetTalk naming service.
VINES applications on servers that are not equipped with the Server-to-Server option can route data through foreign host gateways. This is accomplished by first routing data to a server equipped with the Server-to-Server option.
Figure 1-2 shows two servers with the Server-to-Server option installed exchanging VINES traffic through an IP network.
For details on the TCP/IP Server-to-Server option, see Chapter 2.
A server equipped with the Server-to-Server option can control the kinds of VINES traffic that enter its network from attached IP networks. For more information, see Managing VINES Security.
Both the Routing and the Server-to-Server options allow your server to route IP traffic over multiple types of LANs if your server is equipped with the appropriate LAN cards. For example, both options allow your server to route data from a host on an Ethernet LAN to a host on a IEEE 802.5 Token-Ring LAN. If you need to install LAN cards, see the appropriate Banyan LAN installation documents for more information.
Note: As a network manager, you may be responsible for managing communications for several servers. Throughout this manual, the term "your server" means any server that you are managing.
The data links supported are:
Ethernet IEEE 802.5 Token-Ring FDDI (Fiber Distributed Data Interface) ProNET-10
Contact your Banyan sales representative for more information on the specific LAN cards that the Banyan TCP/IP options support.
To use either TCP/IP option (Routing or Server-to-Server), your server must be running optional software.
If your server does not have the TCP/IP option software that you plan to use, you must install it. This section presents a summary of what you need to do.
To install either option, follow these steps:
1. From the Operator Menu, choose Shut Down Server Software. A prompt appears asking if you really want to shut down all services.
2. Enter Y. The Shut Down Menu appears.
3. Select System Maintenance.
4. Select Manage Software Options. The Manage Software Options menu appears.
5. Select INSTALL options.
6. Select Install OPTION CODE options.
7. Enter the Option Code and Option Enabler at the prompts.
8. Press ESC until you return to the System Maintenance menu.
9. Select Return to Operator Menu.
10. Choose Configure/Diagnose Server from the Operator Menu.
11. Choose Add Cards/Change Card Configuration.
12. From the Add/Change Card menu, choose Save Configuration and Exit.
13. Reboot the server.
The software installation process is now complete.
Your Tasks as a Network Manager
As a network manager, you are responsible for configuring and managing the TCP/IP Routing option or the TCP/IP Server-to-Server option on one or more servers. Both options require you to perform the same installation, configuration, and management tasks. The TCP/IP configuration program enables you to manage both options.
The most important management task is to use the TCP/IP configuration program to enter information in a configuration file. Chapter 7 through Chapter 11 discuss how to use the TCP/IP configuration program. The configuration functions are as follows:
Manage Network Interfaces - Allows you to specify information that IP interfaces require. This function also enables you to control interfaces and to manage address resolution over LANs. (See Chapter 4 and Chapter 8.)
Manage Routing through VINES Networks - Allows you to specify other servers equipped with the TCP/IP routing option. You must perform this function to integrate the routing functions of VINES and TCP/IP, which work together to route data between servers in a TCP/IP environment. (See Chapter 6 and Chapter 10.)
Manage Domain Name Settings - Allows you to manage domain name settings for this server. (See Chapter 12.)
Table 1-1 summarizes the TCP/IP configuration functions, and the tasks you perform for each of the two TCP/IP options.
Before you run the configuration program to perform these functions, identify and record all the information you must specify. Each function above has a planning chapter and a chapter on how to use the TCP/IP configuration program to configure your option.
The following is a summary of the network management tasks you perform once hardware and software installation is complete, and the order in which you should perform them:
1. Record the information required to manage interfaces. See Chapter 4.
2. Record the information required to specify the foreign host gateways through which you will be routing TCP/IP traffic. See Chapter 5.
3. Record the information required to route VINES traffic through TCP/IP foreign gateways to other VINES servers. See Chapter 5.
4. Record the information required to specify the VINES Servers through which you will be routing TCP/IP traffic. See Chapter 6.
5. Familiarize yourself with the configuration program. See Chapter 7.
6. Use the configuration program to manage interfaces for TCP/IP. Enter the information you recorded in step 1. See Chapter 8.
7. Use the configuration program to specify all foreign host gateways through which you will be routing TCP/IP traffic. Enter the information you recorded in step 2. See Chapter 9.
8. Use the configuration program to specify the VINES servers through which you will route TCP/IP traffic. Enter the information you recorded in step 3. See Chapter 10.
9. Use the configuration program to specify the VINES servers with which you will establish server-to-server connections. Enter information you recorded in step 4. See Chapter 11.
10. Once your server is properly configured and communicating, perform certain maintenance tasks from time to time. See Chapter 12.
