Chapter 1: Lion Server: An Overview
Alerts: Here, you find alerts that Lion Server can send you. You’re
alerted to conditions of low disk space, possible virus-containing e-mail,
expired SSL certificates, changes to network settings, and available soft-
ware updates. You can also use this pane to designate an e-mail address
where Lion Server can e-mail alerts to you.
Stats: Stats provides live graphs of your server’s processor usage,
memory usage, and network traffic.
Under Hardware, you can click the name of your server to get access to four
panes of information and some settings as well:
Overview: This pane (refer to Figure 1-3) provides information about the
Mac model and hardware configuration, the version of Mac OS X Server,
and how long the server has been running.
Settings: Here, you can change settings for remote login and administra-
tion, screen sharing, push notifications, and SSL certificates.
A check box called Dedicate System Resources To Server Services should
always be checked. Having it uncheck can slow server performance.
Network: This pane displays (and lets you change) the Mac’s computer
name and the server’s hostname. It also displays the IP addresses of
your network interfaces.
Storage: This pane displays the amount of free space on any storage
devices attached to the server. It also lets you change permissions for
shared folders (see Chapter 9).
Server Admin
Server Admin handles more complex tasks than does the Server app. Server
Admin provides more options and much more fine-grained control over the
services it supports. Server Admin also gives you access to services that
aren’t available in the Server app, such as the DNS and push notification serv-
ers, firewall, and the software update server. Figure 1-6 shows Server Admin’s
Overview pane. Server Admin also can keep track of multiple servers and the
services they’re running.
Configuring Services with Server Admin
You can use Server Admin to configure and manage Lion Server’s many ser-
vices, including Open Directory. To get Server Admin running for the first
time, follow these steps:
1. If you’re not already logged in to the server Mac, log in as the local
administrator.
2. Open Server Admin from the /Applications/Server folder.
