6 Setting Network Preferences

Use this chapter to learn the commands to change network

settings on a server.

Mac OS X Server provides command-line control to manage servers in a mixed-

platform environment and to configure, deploy, and manage powerful network

services. These tools make it easy to configure and maintain core network services,

while providing the advanced features and functionality required by experienced

IT professionals.

Configuring Network Interfaces

To configure network interfaces, Mac OS X Server provides networksetup and

serversetup. Although ifconfig (the standard UNIX tool for configuring networks) is

available, it’s better to use networksetup and serversetup because if you use ifconfig,

your computer will be out of sync and will revert to using the contents of

preferences.plist after a restart.

You can still use ifconfig to view the network interface configuration. This is

particularly beneficial when your computer is using an autonegotiated Ethernet

connection.

For more information, see the networksetup and serversetup man pages.

Managing Network Interface Information

This section describes commands you address to a specific hardware device

(for example, en0) or port (for example, Built-in Ethernet).

If you prefer to work with network port configurations following the approach used in

the Network preferences pane of System Preferences, see the commands in “Managing

Network Port Configurations” on page 67.
