How to Use This Manual

This manual explains how to install and use JOIN, including how to customize JOIN to reflect your specific network configuration.

JOIN software is a powerful and easy-to-use implementation of the Dynamic Host Configuration Protocol (DHCP) that automates and centralizes network administration. JOIN facilitates network administration by allowing:

This manual contains the following information:

Chapter 1, Installation, explains how to install and start JOIN.

Chapter 2, "DHCP and Migration Strategy", provides a DHCP overview, and describes options for DHCP migration.

Chapter 3, "Configure with xjoin", explains how to configure JOIN using the xjoin GUI.

Chapter 4, "Configure without xjoin", describes how to manually edit configuration files and use JOIN command line utilities.

Chapter 5, "Server/Security Parameters", explains how to set options for IP addresses, hostnames available for assignment to JOIN clients, and how you check the status of IP addresses.

Chapter 6, "Subnet Parameters", explains how you can customize the JOIN database to reflect the subnetwork specifications of your network.

Chapter 7, "Node Parameters", explains how you can customize the JOIN database to reflect the parameters for each DHCP client of your network.

Chapter 8, "Group Parameters", describes creating groups of nodes that share configuration settings.

Chapter 9, "Parameter Descriptions", describes options for Network, Lease, Time, BOOTP, NetBIOS, X Window, TCP, IP, and Link parameters.

Chapter 10, "Frequently Asked Questions", provides answer to common questions.

Appendix A, "Sample Installations", provides a sample installation and upgrade log files.

Appendix B, "Server Logic", describes the concept of dynamic naming and JOIN client configuration parameters.

Appendix C, "The JOIN Client", describes JOIN client software.

Appendix D, "License Management", describes JOIN DHCP client addressing and service.

Note: Before you begin, you should be comfortable with your native UNIX operating system and have a working knowledge of your computer. You should understand:

Terminology

client

A computer (node) on a network that uses services provided by a server.

client identifier

An opaque cookie, guaranteed to uniquely identify a specific client machine. It can be either the hardware address (MAC address) of the client's network interface card or a user-determined identifier.

domain name

A domain represents computers that are grouped together for administrative reasons. Domain names are usually assigned to a company, and make administering the domain easy.

Domain Name Service

The name service of the TCP/IP protocol family, which provides information about computers on local and remote networks.

Dynamic Host Configuration Protocol (DHCP)

The protocol that enables automatic assignment of IP addresses and other network parameters from an address pool. See RFC1533 for more detail.

host

A computer attached to a network.

IP address

A unique number that identifies each host in a network or an entire network.

In a network, the IP address identifies the computer or peripheral to other devices in the same environment. Entering information as simple as subnet masks, IP addresses, and default gateways can create network problems because the information entered may be inconsistent across all devices on the network.

IP network number

A unique number that identifies each IP network.

network mask

A number used to separate the local subnet address from the rest of a given IP address.

node

A network computer that uses services provided by a server.

ping

The ping command can be used to find out if an IP address on the network is available. When ping sends an echo request, the client responds with an echo reply.

server

A network computer that provides services to networked client computers.

subnet

A networking scheme that divides a single logical network into smaller physical networks to simplify routing.

subnet number

The part of an IP address that refers to a specific subnet.
