39Chapter 2 Getting Ready for Mac OS X Server
Sets up the server’s rewall to block incoming connections that originate from Â
computers on the Internet. The rewall allows outgoing connections from computers
on the local network. It also allows incoming connections that are responding to the
local computers’ outgoing connections. After setup, you can use the Security pane
of Server Preferences to allow incoming requests through the rewall for specic
services.
Sets up DNS service for the local network, and congures it to cache DNS name Â
lookups to improve performance for local network computers.
Deciding How to Manage Users and Groups
During the initial setup of Mac OS X Server, you’ll choose how the server manages the
user and group accounts it uses to authenticate users and determine which services
they’re allowed to access. You can choose to:
Manage users and groups independently for a small organization Â
Import users and groups for a workgroup in a medium or large organization Â
Congure manually for a server that provides selected services to a medium or large Â
organization
Managing Your Own Users and Groups
If you’re setting up a server for a small organization without an existing directory
server, you can choose to set up an independent server with its own users and groups.
The server provides its own directory service, as an Open Directory master, for its user
and group accounts.
