5 Network Setup Tool
You can configure settings for network hardware ports such as your server’s built-in
Ethernet, Ethernet cards, or serial port. Mac OS X also supports multihoming, which means
that multiple network services can be active at the same time. With multihoming, you can
also have multiple IP configurations on a single network hardware port.
On a computer running Mac OS X, you can configure network services in the Network pane
of System Preferences. In Mac OS X Server, you can either connect a keyboard and monitor
to a server and edit these settings locally, or you can use the Network Setup command-line
tool to configure network services on a server remotely.
A “network service” is a complete collection of settings for a specific network hardware port.
You may have one or several network services for a given hardware port.
The Network Setup Tool allows you to
m enable or disable network services
m create new network services
m set the order of network services
m configure the TCP/IP options of the network services
m set other networking options for the services, such as proxy server information
Using Network Setup
Network Setup is a command-line tool that you use with a terminal application and SSH
(Secure Shell). Mac OS X comes with a terminal application called Terminal. You can find this
application in
/Applications/Utilities
If you’re not familiar with command-line tools and SSH, read Chapter 4, “Using Command-
Line Tools.”
