Preface
Audience
The target audience for this reference guide consists of:
•
Administrators that are responsible for configuring and managing a NetDefendOS
installation.
•
Administrators that are responsible for troubleshooting a NetDefendOS installation.
This guide assumes that the reader is familiar with NetDefendOS and understands the
fundamentals of IP network security.
Notation
The following notation is used throughout this reference guide when specifying the parameters
of a log message:
Angle Brackets <name>
Used for specifying the name of a log message parameter.
Square Brackets [name]
Used for specifying the name of a conditional log message
parameter.
Example 1. Log Message Parameters
Log Message
New configuration activated by user <username>, and committed via
<authsystem>
Parameters
authsystem
username
Both the authsystem and the username parameters will be included.
Example 2. Conditional Log Message Parameters
Log Message
Administrative user <username> logged in via <authsystem>. Access level:
<access_level>
Parameters
authsystem
username
access_level
[userdb]
[server_ip]
[server_port]
[client_ip]
[client_port]
The authsystem, username and the access_level parameters will be included. The other
parameters of userdb, server_ip, server_port, client_ip and client_port may or may not be included,

Chapter 1: Introduction
• Log Message Structure, page 36
• Context Parameters, page 38
• Severity levels, page 43
This guide is a reference for all log messages generated by NetDefendOS. It is designed to be a
valuable information source for both management and troubleshooting.
1.1. Log Message Structure
All log messages have a common design with attributes that include category, severity and
recommended actions. These attributes enable the easy filtering of log messages, either within
NetDefendOS prior to sending them to a log receiver, or as part of analysis that takes place after
the logging and storage of messages on an external log server.
The following information is provided for each specific log message:
Name
The name of the log message, which is a short string, 1-6 words
separated by _. Please note that the name cannot be used as a
unique identification of the log message, as several log messages
might share the same name.
ID
The ID is a number made up of a string of 8 digits which uniquely
identifies the log message. The first 3 digits identify the category to
which the log message belongs.
Note
In this guide, the Name and the ID of the log message
form the title of the section describing the log message.
Category
Log messages are grouped into categories, where each category
maps to a specific subsystem in NetDefendOS. For instance, the
IPSEC category includes some hundreds of log messages, all related
to IPSec VPN activities. Other examples of categories include ARP,
DHCP, IGMP and USERAUTH.
In this guide, categories are listed as sections in Chapter 2, Log
36
Chapter 1: Introduction
Message Reference.
As previously mentioned, the category is identified by the first 3
digits in the message ID. All messages in a particular category have
the same first 3 digits in their ID.
Default Severity
The default severity level for this log message. For a list of severity
levels, please see section Section 1.3, “Severity levels”.
Log Message
A brief explanation of the event that took place. This explanation
often features references to parameters, enclosed in angle brackets.
Example:
Administrative user <username> logged in via <authsystem>. Access
level: <access_level>
Note that this information is only featured in this reference guide,
and is never actually included in the log message.
Explanation
A detailed explanation of the event.
Note that this information is only featured in this reference guide,
and is never actually included in the log message.
Gateway Action
A short string, 1-3 words separated by _, of what action
NetDefendOS will take. If the log message is purely informative, this
is set to "None".
Recommended Action
A detailed recommendation of what the administrator should do if
this log message is received. If the log message is purely informative,
this is set to "None".
Note that this information is only featured in this reference guide,
and is never actually included in the log message.
Revision
The current revision of the log message. This is increased each time
a log message is changed between two releases.
Additional Information
Depending on the log message, the following information may also be included:
Parameters
The name of the parameters that are included in this log message. If
a parameter is specified within square brackets (for example
[username]), then the parameter is optional and may or may not be
included in the log message.
Context Parameters
The name of the context parameters that are included in this log
message. Please see Section 1.2, “Context Parameters” for a
description of all available context parameters.
37
Chapter 1: Introduction
1.2. Context Parameters
In many cases, information regarding a certain object is featured in the log message. This can be
information about, for example, a connection. In this case, the log message should, besides all
the normal log message attributes, also include information about which protocol is used, source
and destination IP addresses and ports (if applicable), and so on.
As the same information will be included in many log messages, these are referenced as a
Context Parameter. So whenever a log message includes information about a connection, it will
feature the CONN parameter in the Context Parameter list. This means that additional

1.3. Severity levels
An event has a default severity level, based on how serious the event is. The following eight
severity levels are possible, as defined by the Syslog protocol:
0 - Emergency
Emergency conditions, which most likely led to the system being
unusable.
1 - Alert
Alert conditions, which affected the functionality of the unit. Needs
attention immediately.
2 - Critical
Critical conditions, which affected the functionality of the unit. Action
should be taken as soon as possible.
3 - Error
Error conditions, which probably affected the functionality of the unit.
4 - Warning
Warning conditions, which could affect the functionality of the unit.
5 - Notice
Normal, but significant, conditions.
6 - Informational
Informational conditions.
7 - Debug
Debug level events.
Priority in Syslog Messages
In Syslog messages the priority is indicated by the parameter prio=nn.
Excluding Logged Messages
NetDefendOS allows the exclusion from logging of entire catageories of log messages or just
specific log messages. It is also possible to change the severity level of log messages so that a
specific category or a specific message has the severity reset to a particular level when it is sent
by NetDefendOS. These features are documented further in the NetDefendOS Administrators
Guide.
