Examples and Formatting
xvii
4. Examples and Formatting
All of the examples for Red Hat Certificate System commands, file locations, and other usage are
given for Red Hat Enterprise Linux 5 systems. Be certain to use the appropriate commands and files
for your platform.
To start the Red Hat Certificate System:
/etc/init.d/rhpki-ca start
Example 1. Example Command
All of the tools for Red Hat Certificate System are located in the /usr/bin directory. These tools can
be run from any location without specifying the tool location.
There is another important consideration with the LDAP utilities. The LDAP tools referenced in
this guide are Mozilla LDAP, installed with Red Hat Certificate System in the /usr/dir/mozldap
directory on Red Hat Enterprise Linux.
However, Red Hat Enterprise Linux systems also include LDAP tools from OpenLDAP in the /usr/
bin directory. It is possible to use the OpenLDAP commands as shown in the examples, but you must
use the -x argument to disable SASL, which OpenLDAP tools use by default.
Certain words are represented in different fonts, styles, and weights. Different character formatting is
used to indicate the function or purpose of the phrase being highlighted.
Formatting Style Purpose
Monospace font Monospace is used for commands, package names, files and
directory paths, and any text displayed in a prompt.
Monospace
with a
background
This type of formatting is used for anything entered or returned
in a command prompt.
Italicized text Any text which is italicized is a variable, such as
instance_name or hostname. Occasionally, this is also used to
emphasize a new term or other phrase.
Bolded text Most phrases which are in bold are application names, such as
Cygwin, or are fields or options in a user interface, such as a
User Name Here: field or Save button.
Other formatting styles draw attention to important text.
NOTE
A note provides additional information that can help illustrate the behavior of the system or
provide more detail for a specific issue.
IMPORTANT
Important information is necessary, but possibly unexpected, such as a configuration
change that will not persist after a reboot.

A warning indicates potential data loss, as may happen when tuning hardware for
maximum performance.
5. Additional Reading
The Certificate System Administrator's Guide describes how to set up, configure, and administer the
Certificate System subsystems and how to configure backend certificate management functions, such
as publishing and logging. The Administrator's Guide also describes how to configure subsystems to
relate to one another to manage certificates and tokens and how to manage certificates and tokens;
this guide is targeted for Certificate System administrators.
The Certificate System Agent's Guide describes how agents — users responsible for processing
certificate requests and managing other aspects of certificate management — can use the Certificate
System subsystems web services pages to process certificate requests, key recovery, OCSP requests
and CRLs, and other functions.
The documentation for Certificate System includes the following guides:
• Certificate System Administrator's Guide explains all administrative functions for the Certificate
System, such as adding users, creating and renewing certificates, managing smart cards, publishing
CRLs, and modifying subsystem settings like port numbers.
• Certificate System Agent's Guide details how to perform agent operations for the CA, RA, DRM, and
TPS subsystems through the Certificate System agent services interfaces.
• Certificate System Command-Line Tools Guide covers the command-line scripts supplied with Red
Hat Certificate System.
• Managing Smart Cards with the Enterprise Security Client explains how to install, configure, and use
the Enterprise Security Client, the user client application for managing smart cards, user certificates,
and user keys.
• Certificate System Migration Guides cover version-specific procedures for migrating from older
versions of Certificate System to Red Hat Certificate System 7.2.
• Release Notes contains important information on new features, fixed bugs, known issues and
workarounds, and other important deployment information for Red Hat Certificate System 7.2.
Additional Certificate System information is provided in the Certificate System SDK, an online
reference to HTTP interfaces, javadocs, samples, and tutorials related to Certificate System. A
downloadable zip file of this material is available for user interaction with the tutorials.
For the latest information about Red Hat Certificate System, including current release notes, complete
product documentation, technical notes, and deployment information, see http://www.redhat.com/docs/
manuals/cert-system/.
6. Giving Feedback
If there is any error in this Administrator's Guide or there is any way to improve the documentation,
please let us know. Bugs can be filed against the documentation for Red Hat Certificate System
Document History
xix
through Bugzilla, http://bugzilla.redhat.com/bugzilla. Make the bug report as specific as possible, so
we can be more effective in correcting any issues:
• Select the Red Hat Certificate System product.
• Set the component to Doc - administration-guide.
• Set the version number to 7.2.
• For errors, give the page number (for the PDF) or URL (for the HTML), and give a succinct
description of the problem, such as incorrect procedure or typo.
For enhancements, put in what information needs to be added and why.
• Give a clear title for the bug. For example, "Incorrect command example for setup
script options" is better than "Bad example".
We appreciate receiving any feedback — requests for new sections, corrections, improvements,
enhancements, even new ways of delivering the documentation or new styles of docs. You are
welcome to contact Red Hat Content Services directly at [email protected].
