About This Book

Notation Conventions

The following conventions are used throughout this book.

Summary

Notation Indicates
monospaced font A command or other terminal text $ A shell prompt [text_in_brackets] An optional parameter (one|other) Alternative parameters (type one or the other) underlined [...] A parameter that may be repeated <anglebrackets> A displayed value that depends on your server configuration
A parameter you must replace with a value
Preface

Commands and Other Terminal Text

Commands or command parameters that you might type, along with other text that normally appears in a Terminal window, are shown in this font. For example,
You can use the doit command to get things done.
When a command is shown on a line by itself as you might type it in a Terminal window, it follows a dollar sign that represents the shell prompt. For example,
$ doit
To use this command, type “doit” without the dollar sign at the command prompt in a Terminal window, then press the Return key.

Command Parameters and Options

Most commands require one or more parameters to specify command options or the item to which the command is applied.
11
Parameters You Must Type as Shown
If you need to type a parameter as shown, it appears following the command in the same font. For example,
$ doit -w later -t 12:30
To use the command in the above example, type the entire line as shown.
Parameter Values You Provide
If you need to supply a value, its placeholder is underlined and has a name that indicates what you need to provide. For example,
$ doit -w later -t hh:mm
In the above example, you need to replace hh with the hour and mm with the minute, as shown in the previous example.
Optional Parameters
If a parameter is available but not required, it appears in square brackets. For example,
$ doit [-w later]
To use the command in the above example, type either doit or doit -w later. The result might vary but the command will be performed either way.
Alternative Parameters
If you need to type one of a number of parameters, they’re separated by a vertical line and grouped within parentheses ( | ). For example,
$ doit -w (now|later)
To perform the command, you must type either doit -w now or doit -w later.

Default Settings

Descriptions of server settings usually include the default value for each setting. When this default value depends on other choices you’ve made (such as the name or IP address of your server, for example), it’s enclosed in angle brackets <>.
For example, the default value for the IMAP mail server is the host name of your server. This is indicated by mail:imap:servername = "<hostname>".

Commands Requiring Root Privileges

Throughout this guide, commands that require root privileges begin with sudo.
12 Preface About This Book

1 Typing Commands

1
How to use Terminal to execute commands, connect to a remote server, and view online information about commands and utilities.
To access a UNIX shell command prompt, you open the Terminal application. In Terminal, you can use the ssh command to log in to other servers. You can use the man command to view online documentation for most common commands.

Using Terminal

To enter shell commands or run server command-line tools and utilities, you need access to a UNIX shell prompt. Both Mac OS X and Mac OS X Server include Terminal, an application you can use to start a UNIX shell command-line session on the local server or on a remote server.
To open Terminal:
m
Click the Terminal icon in the dock or double-click the application icon in the Finder (in /Applications/Utilities).
Terminal presents a prompt when it’s ready to accept a command. The prompt you see depends on Terminal and shell preferences, but often includes the name of the host you’re logged in to, your current working directory, your user name, and a prompt symbol. For example, if you’re using the default bash shell and the prompt is
server1:~ admin$
you’re logged in to a computer named “server1” as the user named “admin” and your current directory is the admin’s home directory (~).
Throughout this manual, wherever a command is shown as you might type it, the prompt is abbreviated as $.
13
To type a command:
m
Wait for a prompt to appear in the Terminal window, then type the command and press Return.
If you get the message command not found, check your spelling. If the error recurs, the program you’re trying to run might not be in your default search path. Add the path before the program name or change your working directory to the directory that contains the program. For example:
[server:/] admin$ serversetup -getAllPort serversetup: Command not found. [server:/] admin$ /System/Library/ServerSetup/serversetup -getAllPort 1 Built-in Ethernet [server:/] admin$ cd /System/Library/ServerSetup [server:/System/Library/ServerSetup] admin$ ./serversetup -getAllPort 1 Built-in Ethernet [server:/System/Library/ServerSetup] admin$ cd / [server:/] admin$ PATH = "$PATH:/System/Library/ServerSetup" [server:/] admin$ serversetup -getAllPort 1 Built-in Ethernet

Correcting Typing Errors

To correct a typing error before you press Return to issue the command, use the Delete key or press Control-H to erase unwanted characters and retype.
To ignore what you have typed and start again, press Control-U.

Repeating Commands

To repeat a command, press Up-Arrow until you see the command, then press Return.
To repeat a command with modifications, press Up-Arrow until you see the command, press Left-Arrow or Right-Arrow to skip over parts of the command you don’t want to change, press Delete to remove characters, type regular characters to insert them, then press Return to execute the command.

Including Paths Using Drag-and-Drop

To include a fully-qualified file name or directory path in a command, stop typing where the item is required in the command and drag the folder or file from a Finder window into the Terminal window.
14 Chapter 1 Typing Commands

Commands Requiring Root Privileges

Many commands used to manage a server must be executed by the root user. If you get a message such as “permission denied,” the command probably requires root privileges.
To issue a single command as the root user, begin the command with sudo. For example:
$ sudo serveradmin list
You’re prompted for the root password if you haven’t used sudo recently. The root user password is set to the administrator user password when you install Mac OS X Server.
To switch to the root user so you don’t have to repeatedly type sudo, use the su command:
$ su root
You’re prompted for the root user password and then are logged in as the root user until you log out or use the su command to switch to another user.
Important: As the root user, you have sufficient privileges to do things that can cause
your server to stop working properly. Don’t execute commands as the root user unless you understand clearly what you’re doing. Logging in as an administrative user and using sudo selectively might prevent you from making unintended changes.
Throughout this guide, commands that require root privileges begin with sudo.
Chapter 1 Typing Commands 15

Sending Commands to a Remote Server

Secure Shell (SSH) lets you send secure, encrypted commands to a server over the network. You can use the ssh command in Terminal to open a command-line connection to a remote server. While the connection is open, commands you type are performed on the remote server.
Note: You can use any application that supports SSH to connect to Mac OS X Server.
To open a connection to a remote server:
1 Open Terminal.
2 Type the following command to log in to the remote server:
ssh -l username server
where username is the name of an administrator user on the remote server and
server is the name or IP address of the server.
Example: ssh -l admin 10.0.1.2
3 If this is the first time you’ve connected to the server, you’re prompted to continue
connecting after the remote computer’s RSA fingerprint is displayed. Type yes and press Return.
4 When prompted, type the user’s password (the user’s password on the remote server)
and press Return.
The command prompt changes to show that you’re now connected to the remote server. In the case of the above example, the prompt might look like
[10.0.1.2:~] admin$
5 To send a command to the remote server, type the command and press Return.
To close a remote connection
m
Type logout and press Return.

Sending a Single Command

You can authenticate and send a command using a single typed line by appending the command you want to execute to the basic ssh command.
For example, to delete a file you could type
$ ssh -l admin server1.company.com rm /Users/admin/Documents/report
or
$ ssh -l admin@server1.company.com "rm /Users/admin/Documents/report"
You’re prompted for the user’s password.
16 Chapter 1 Typing Commands

Updating SSH Key Fingerprints

The first time you connect to a remote server using SSH, the local computer asks if it can add the remote server’s “fingerprint” (a security key) to a list of known remote computers. You might see a message like this:
The authenticity of host "server1.company.com" can’t be established. RSA key fingerprint is a8:0d:27:63:74:f1:ad:bd:6a:e4:0d:a3:47:a8:f7. Are you sure you want to continue connecting (yes/no)?
Type yes and press Return to finish authenticating.
If you later see a warning message about a “man-in-the-middle” attack when you try to connect, it might be because the key on the remote computer no longer matches the key stored on the local computer. This can happen if you:
Change your SSH configuration
Perform a clean install of the server software
Start up from a Mac OS X Server CD
To connect again, delete the entries corresponding to the remote computer (which can be stored by both name and IP address) in the file ~/.ssh/known_hosts.
Important: Removing an entry from the known_hosts file bypasses a security
mechanism that helps you avoid imposters and “man-in -the-middle” attacks. Be sure you understand why the key on the remote computer has changed before you delete its entry from the known_hosts file.

Notes on Communication Security and servermgrd

When you use the Server Admin GUI application or the serveradmin command-line tool, you’re communicating with a local or remote servermgrd process.
servermgrd uses SSL for encryption and client authentication but not for user
authentication, which uses HTTP basic authentication along with Directory Services.
servermgrd uses a self-signed (test) SSL certificate installed by default in
/etc/servermgrd/ssl.crt/. You can replace this with an actual certificate.
The default certificate format for SSLeay/OpenSSL is PEM, which actually is Base64
encoded DER with header and footer lines (from www.modssl.org).
servermgrd checks the validity of the SSL certificate only if the “Require valid digital
signature” option is checked in Server Admin preferences. If this option is enabled, the certificate must be valid and not expired or Server Admin will refuse to connect.
The SSLOptions and SSLRequire settings determine what SSL encryption options are
used. By default, they’re set as shown below but can be changed at any time by editing /etc/servermgrd/servermgrd.conf, port 311.
SSLCertificateFile /private/etc/servermgrd/ssl.crt/server.crt SSLCertificateKeyFile /private/etc/servermgrd/ssl.key/server.key SSLCipherSuite
ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
SSLOptions +StdEnvVars
Chapter 1 Typing Commands 17

Using Telnet

Because it isn’t as secure as SSH, Telnet access isn’t enabled by default.
To enable Telnet access:
$ service telnet start
To disable Telnet access:
$ service telnet stop

Getting Online Help for Commands

Onscreen help is available for most commands and utilities.
Note: Not all techniques work for all commands, and some commands have no onscreen help.
To view onscreen information about a command, try the following:
Type the command without any parameters or options. This will often list a summary
of options and parameters you can use with the command. Example:
$ sudo serveradmin
Type man command, where command is the command you’re curious about. This
usually displays detailed information about the command, its options, parameters, and proper use. Example:
$ man serveradmin
For help using the man command, type:
$ man man
Type the command followed by a -help, -h, --help, or help parameter.
Examples:
$ hdiutil help $ dig -h $ diff --help
18 Chapter 1 Typing Commands

Notes About Specific Commands and Tools

serversetup

The serversetup utility is located in /System/Library/ServerSetup. To run this command, you can type the full path, for example:
$ /System/Library/ServerSetup/serversetup -getAllPort
Or, if you want to use the utility to perform several commands, you can change your working directory and type a shorter command:
$ cd /System/Library/ServerSetup $ ./serversetup -getAllPort $ ./serversetup -getDefaultInfo
or add the directory to your search path for this session and type an even shorter command:
$ PATH = "$PATH:/System/Library/ServerSetup" $ serversetup -getAllPort
To permanently add the directory to your search path, add the path to the file /etc/profile.

serveradmin

You can use the serveradmin tool to perform many service-related tasks. You’ll see it used throughout this guide.
Determining Whether a Service Needs to be Restarted
Some services need to be restarted after you change certain settings. If a change you make using a service’s writeSettings command requires that you restart the service, the output from the command includes the setting <svc>:needsRecycleOrRestart with a value of yes.
Important: The needsRecycleOrRestart setting is displayed only if you use the
serveradmin svc:command = writeSettings command to change settings. You
won’t see it if you use the serveradmin settings command.
Chapter 1 Typing Commands 19
2 Installing Server Software and
Finishing Basic Setup
2
Commands you can use to install, set up, and update Mac OS X Server software on local or remote computers.

Installing Server Software

You can use the installer command to install Mac OS X Server or other software on a computer. For more information, see the man page.

Automating Server Setup

Normally, when you install Mac OS X Server on a computer and restart, the Server Assistant opens and asks you to provide the basic information necessary to get the server up and running (for example, the name and password of the administrator user, the TCP/IP configuration information for the server’s network interfaces, and how the server uses directory services). You can automate this initial setup task by providing a configuration file that contains these settings. Servers starting up for the first time look for this file and use it to complete initial server setup without user interaction.

Creating a Configuration File Template

An easy way to prepare configuration files to automate the setup of a group of servers is to start with a file saved using the Server Assistant. You can save the file as the last step when you use the Server Assistant to set up the first server, or you can run the Server Assistant later to create the file. You can then use that first file as a template for creating configuration files for other servers. You can edit the file directly or create scripts to create customized configuration files for any number of servers that use similar hardware.
To save a template configuration file during server setup:
1 In the final pane of the Server Assistant, after you review the settings, click Save As.
2 In the dialog that appears, choose Configuration File next to “Save as” and click OK.
So you can later edit the file, don’t select “Save in Encrypted Format.”
3 Choose a location to save the file and click Save.
21
To create a template configuration file at any time after initial setup:
1 Open the Server Assistant (in /Applications/Server).
2 In the Welcome pane, choose “Save setup information in a file or directory record” and
click Continue.
3 Enter settings on the remaining panes, then, after you review the settings in the final
pane, click Save As.
4 In the dialog that appears, choose Configuration File next to “Save as” and click OK.
So you can later edit the file, don’t select “Save in Encrypted Format.”
5 Choose a location to save the file and click Save.

Creating Customized Configuration Files from the Template File

After you create a template configuration file, you can modify it directly using a text editor or write a script to automatically generate custom configuration files for a group of servers.
The file uses XML format to encode the setup information. The name of an XML key reveals the setup parameter it contains.
The following example shows the basic structure and contents of a configuration file for a server with the following configuration:
An administrative user named “Administrator” (short name “admin”) with a user ID of
501 and the password “secret”
A computer name and host name of “server1.company.com”
A single Ethernet network interface set to get its address from DHCP
No server services set to start automatically

Note: The actual contents of a configuration file depend on the hardware configuration of the computer on which it’s created. This is one reason you should start from a template configuration file created on a computer similar to those you plan to set up.
24 Chapter 2 Installing Server Software and Finishing Basic Setup

Naming Configuration Files

The Server Assistant recognizes configuration files with these names:
MAC-address-of-server.plist
IP-address-of-server.plist
hardware-serial-number-of-server.plist
full-host-name-of-server.plist
generic.plist
The Server Assistant uses the file to set up the server with the matching address, name, or serial number. If the Server Assistant cannot find a file named for a particular server, it will use the file named generic.plist.

Storing a Configuration File in an Accessible Location

The Server Assistant looks for configuration files in the following locations:
/Volumes/vol/Auto Server Setup/
where vol is any device volume mounted in the /Volumes directory.
Devices you can use to provide configuration files include
A partition on one of the server’s hard disks
An iPod
An optical (CD or DVD) drive
A USB or FireWire drive
Any other portable storage device that mounts in the /Volumes directory

Changing Server Settings

After initial setup, you can use a variety of commands to view or change Mac OS X Server configuration settings.
For information on changing general system preferences, see Chapter 4, “Setting General System Preferences,” on page 31.
For information on changing network settings, see Chapter 5, “Network Preferences,” on page 37.
For information on changing service-specific settings, see the chapter that covers the service.

Viewing, Validating, and Setting the Software Serial Number

You can use the serversetup command to view or set the server’s software serial number or to validate a server software serial number. The serversetup utility is located in /System/Library/ServerSetup.
To display the server’s software serial number:
$ serversetup -getSerialNumber
To set the server software serial number:
$ sudo serversetup -setSerialNumber serialnumber
Parameter Description
serialnumber
A valid Mac OS X Server software serial number, as found on the software packaging that comes with the software.
To validate a server software serial number:
$ serversetup -verifySerialNumber serialnumber
Displays 0 if the number is valid, 1 if it isn’t.

Updating Server Software

You can use the softwareupdate command to check for and install software updates over the web from Apple’s website.
To check for available updates:
$ softwareupdate --list
To install an update:
$ softwareupdate --install update-version
Parameter Description
update-version
The hyphenated product version string that appears in the list of updates when you use the --list option.
To view command help:
$ softwareupdate --help

Moving a Server

Try to place a server in its final network location (subnet) before setting it up for the first time. If you’re concerned about unauthorized or premature access, you can set up a firewall to protect the server while you're finalizing its configuration.
If you must move a server after initial setup, you need to change settings that are sensitive to network location before the server can be used. For example, the server's IP address and host name—stored in both directories and configuration files that reside on the server—must be updated.
When you move a server, consider these guidelines:
Minimize the time the server is in its temporary location so the information you need
to change is limited.
Don’t configure services that depend on network settings until the server is in its
final location. Such services include Open Directory replication, Apache settings (such as virtual hosts), DHCP, and other network infrastructure settings that other computers depend on.
Wait to import final user accounts. Limit accounts to test accounts so you minimize
the user-specific network information (such as home directory location) that will need to change after the move.
After you move the server, use the changeip tool to change IP addresses, host
names, and other data stored in Open Directory NetInfo and LDAP directories on the server. See “Changing a Server’s IP Address” on page 39. You may need to manually adjust some network configurations, such as the local DNS database, after using the tool.
Reconfigure the search policy of computers (such as user computers and DHCP
servers) that have been configured to use the server in its original location.

3 Restarting or Shutting Down a
Server
3
Commands you can use to shut down or restart a local or remote server.

Restarting a Server

You can use the reboot or shutdown -r command to restart a server at a specific time. For more information, see the man pages.

Examples

To restart the local server:
$ shutdown -r now
To restart a remote server immediately:
$ ssh -l root server shutdown -r now
To restart a remote server at a specific time:
$ ssh -l root server shutdown -r hhmm
Parameter Description
server hhmm
The IP address or DNS name of the server.
The hour and minute when the server restarts.

Automatic Restart

You can also use the systemsetup command to set up the server to start automatically after a power failure or system freeze. See “Viewing or Changing Automatic Restart Settings” on page 33.

Changing a Remote Server’s Startup Disk

You can change a remote server’s startup disk using SSH.
To change the startup disk:
Log in to the remote server using SSH and type
$ bless -folder "/Volumes/disk/System/Library/CoreServices" -setOF
Parameter Description
disk
The name of the disk that contains the desired startup volume.
For information on using SSH to log in to a remote server, see “Sending Commands to a Remote Server” on page 16.

Shutting Down a Server

You can use the shutdown command to shut down a server at a specific time. For more information, see the man page.

Examples

To shut down a remote server immediately:
$ ssh -l root server shutdown -h now
To shut down the local server in 30 minutes:
$ shutdown -h +30
Parameter Description
server
The IP address or DNS name of the server.
