Chapter 1
Getting Started
This chapter provides an overview of the Barracuda Control Server and describes important concepts.
Overview .............................................................................................. 6
Concepts .............................................................................................. 6
Getting Started 5
Overview
The Barracuda Control Server web interface enables administrators to monitor and configure multiple
Barracuda Networks products from a single console. Through the web interface, you can check the
health of all connected devices, run reports that are generated by gathering data from all the devices,
and assign roles with varied permissions to different types of users.
The Barracuda Control Server web interface provides for convenient configuration and management
of multiple Barracuda Networks device settings, while providing a view of each device web interface
for individual configuration or reporting.
Key statistics can be viewed by device type at a glance on the CLOUD CONTROL >Status page of the
web interface with the ability to drill down for more detail into the individual web interface for each
connected device.
This guide walks you through installation and initial configuration of your Barracuda Control Server,
and provides concepts and examples to help you understand how to manage Barracuda Networks
products with the Barracuda Control Server web interface according to your organization’s
deployment needs and security policies.
Concepts
Understanding these concepts enables you to take full advantage of the Barracuda Control Server
features for configuring and synchronizing settings on individual or groups of Barracuda Networks
products.
Administrator Access
There are two different administrator accounts:
• Barracuda Control Server Administrator Account – Manage and configure the Barracuda
Control Server. To configure and manage the Barracuda Control Server, log into the system
using admin as your user name and password. Once logged in, you can view and manage the
device, update security definitions, manage the displayed image, troubleshoot the device, and
view tasks and task errors.
• Barracuda Control Server Account Admin – Manage and connect products through the
Barracuda Control Server web interface. Create users and assign various permissions to each
user for access to the Barracuda Control Server, connect devices, and view device status.
Use the web interface to link your Barracuda Network devices including:
•
•
•
•
•
•
Barracuda Spam Firewall
Barracuda Web Filter
Barracuda Web Application Firewall
Barracuda Message Archiver
Barracuda Link Balancer
Barracuda Load Balancer
When you log in to the Barracuda Control Server as the account admin, the connected devices display
in the left pane.

Barracuda Control Server Administrator’s Guide
Management Contexts
There are three ‘contexts’ you use to administer the Barracuda Control Server web interface and the
connected products. These contexts include:
• The Cloud Control context; for managing Barracuda Control Server web interface
configuration;
• The Product context; for managing an individual Barracuda Networks product using the
product web interface;
• The Group context; for managing a group of the same type of Barracuda Networks products
with one web interface, or for grouping products by company, location, or department.
These contexts are described briefly below.
Cloud Control Context
When you log into the Barracuda Control Server web interface, you first see the Cloud Control
context–on the CLOUD CONTROL > Status page–which displays a snapshot of product traffic
statistics for the connected Barracuda Networks product(s).
The Cloud Control pane on the left displays either a list of individual products connected to the
Barracuda Control Server, or groups of products which you create:
Getting Started 7
The center pane provides an interface for managing your account and for connecting products, as well
as a snapshot of product traffic statistics for all connected products. The Unit Health pane on the right
includes a performance overview, connectivity, firmware, storage, and subscription status for each
individual product organized by product type:
Once you click on an individual product, either in the Cloud Control pane or in the Unit Health pane,
you leave the ‘Cloud Control context’ and drill-down into the product type web interface. The product
web interface displays activity for an individual product if you have only one of that type connected.
If you have multiple of one product type connected, the settings and statistics for all products of that
type display in one web interface as described below.
Group Context
Grouping Barracuda Networks products enables you to manage settings and apply policies across
multiple Barracuda Networks products of the same type from one web interface. You can also use
“grouping” to organize your Barracuda Networks products by location, company, department, etc.,
and you can include products of different types. Grouping happens in one of two ways:
1.
By default, the Barracuda Control Server groups Barracuda Networks products by
product type. For example, if you have two or more Barracuda Web Application Firewalls
connected to a Barracuda Control Server, they are automatically grouped as such. You can then
click on that product type in the Cloud Control pane and see one web interface with aggregated
statistics and settings for all of the devices within that group. From the web interface, you can
set policies for all of the products in the group at the same time since they are the same product
type. This group context also enables reporting on aggregated statistics across a group.
2.
You can create a grouping of two or more products. When you click on that group in the Cloud
Control pane, aggregated statistics display on the Status page for each product type in the group.
Additional reasons to manage products in the group context include:
• If you have many devices in one or more locations, managing them with a central console
enables you to easily track firmware versions across products and keep them up-to-date.
• Grouping devices by location helps you keep track of where each device is physically
located in case it needs service. As long as the unit is joined to the Barracuda Control
Server, you do not need to look up the admin password to configure or update the product.
• Grouping devices of the same type enables viewing ‘exceptions’ in which values for the
same setting differ across the devices.
• Grouping either devices of the same type or of different types provides a performance and
traffic statistic snapshot on the CLOUD CONTROL > Status page for each device in the
group. Statistics are aggregated for devices of the same type.

Barracuda Control Server Administrator’s Guide
Product Context
If you have only one of any Barracuda Networks product type connected to the Barracuda Control
Server, when you click on that product link in the Cloud Control pane or in the Unit Health pane, the
web interface for that individual device displays. From the product web interface, you manage the
individual settings just as you would if you logged into the device directly.
Exceptions
When you have more than one of a Barracuda Networks product type connected to the Barracuda
Control Server, and you view the settings of all of them as a group (with one web interface as
described above), a yellow Exception ( ) icon displays if the value of the setting is not the same on
all devices in the group. When you hover the mouse over the icon, the Barracuda Control Server
clearly indicates what the values for that setting are on each device, so that you can change the settings
if desired. See Dealing With Exceptions for more information and examples.

Barracuda Control Server Administration
When you log into the Barracuda Control Server as the Barracuda Control Server Account Admin,
the Cloud Control context and the CLOUD CONTROL > Status page of the Barracuda Control Server
web interface displays. In this context you view a summary of all devices connected to your
Barracuda Control Server. Any Barracuda Networks products you have already connected are listed
in the left Products pane. The central portion of the page displays aggregated performance and traffic
statistics for all connected devices.
For all devices of the same type, the CLOUD CONTROL > Status page shows a graph and
corresponding table listing statistics aggregated across all devices over the past 30 days. For example,
if you connect multiple Barracuda Web Application Firewalls, the CLOUD CONTROL > Status page
shows a graph and corresponding table listing detected attacks, totaled by attack type (XSS Injections,
Injection Attacks, Cookie Poisoning, etc.), over the past hour, 24 hour period, and grand total since
the last system reset. If you connect multiple Barracuda Web Filters, a table and graph display total
Spyware downloads, Virus Downloads, Policy (number of threats blocked by your configured
policies), etc. aggregated across your connected Barracuda Web Filters.
If you have various different Barracuda Networks products connected to your Barracuda Control
Server, a separate set of statistics displays for each device on the CLOUD CONTROL > Status page.
This is useful for having a ‘snapshot’ of activity on all of your Barracuda Networks products on one
page.
On the right of the page the Unit Health pane summarizes performance statistics for each system by
device type.
From the CLOUD CONTROL tab:
•
•
•
•
•
The Connect Products page gives instructions for adding Barracuda Networks products to the
Barracuda Control Server.
The My Account page enables setting Time Zone, Account Notification Email Address, Account
Name and Account Preferred Time Zone (the default time zone used to display statistics and
report data).
The User Management page lists users including roles, status (Active, Inactive), Administrator
actions, and time zone.
The Audit Log page lists login activity.
The Task Manager page displays tasks and any task errors.
From the product context or group context, you can always return to the Cloud Control context by
clicking the Cloud Control icon in the left pane as shown below.

Barracuda Control Server Administrator’s Guide
Managing Products
Connecting and Disconnecting Devices
You must log into your Barracuda Networks product web interface directly to connect or disconnect
it to/from the Barracuda Control Server.
To connect a product to the Barracuda Control Server, log into the web interface as the Barracuda
Control Server Account Admin, and go to the CLOUD CONTROL > Connect Devices page. Follow the
steps on this page to connect the product.
To disconnect a product from the Barracuda Control Server, log into your Barracuda Networks
product web interface. Go to the ADVANCED > Cloud Control page, click No for Connect to
Barracuda Cloud Control, and click Save Changes. Go to the BASIC > Status page of your product,
and verify that the Cloud Control status displays as Not Connected. When you log into the
Barracuda Control Server, the product no longer displays in the product tree.
The Product Tree
Once you connect one or more Barracuda Networks products (devices) to your Barracuda Control
Server, the products display as a list in the product tree in the Cloud Control pane, and are listed by
product type under Products. If you click Groups, your Barracuda Networks products are listed by
groups you have defined, or you can create new groups.
The Firmware Tree
Click Firmwares in the Cloud Control left pane, and expand the product tree. Each firmware version
displays as a separate folder beneath the device name. Expand the folder to view all devices currently
on that firmware version. The Unit Health Pane indicates whether firmware is the current release or
if a new release is available for download.
The Unit Health Pane
Click Cloud Control above the product tree on the left side of the screen to return to the Cloud
Control context, where you can see the Unit Health pane on the right side of the screen. The Unit
Health pane indicates, for each of the connected Barracuda Networks products, a general status for
performance statistics. Click on the Expand ( ) icon on the right side of the pane to expand the
detailed list of performance statistics for the selected device. This list varies amongst product types.
Managing Products and Groups 23
Figure 4.2: General status for each connected device
Legend for the Unit Health pane is as follows:
• Connectivity: Green indicates device is connected, red indicates device is not connected
• Firmware Version:
- Green indicates current release
- Yellow indicates that a new minor release is available for download
- Red indicates that a new major release is available for download
• Health: General indicator of device performance statistics
• Storage: Green indicates there are no storage issues, red indicates there are storage issues
• Subscription: Green indicates that Energize Updates, Instant Replacement (where
applicable) and Premium Support (where applicable) are current for the device, red
indicates that one or more of these subscription items is either expired or not yet activated
Product Context
When you click on a particular device in the product tree or the Unit Health pane, the unique statistics
and settings for that device display with the same web interface you would see if you logged directly
into the web interface of that device outside of the Barracuda Control Server.
The product web interface displays settings only for that device. For the selected product, you can
view and change all settings available from within the Barracuda Control Server web interface; note
that some settings are not available from within the Barracuda Control Server web interface and must
be configured from logging into the device directly from your browser. Pages or settings not available
from within the Barracuda Control Server are grayed out.
24
Barracuda Control Server Administrator’s Guide
Interpreting Device Statistics
The CLOUD CONTROL > Status page provides an overview of the performance and health of all of
the Barracuda Networks devices connected to the Barracuda Control Server. In this view, the same
traffic and performance statistics available in the BASIC > Status page for your other Barracuda
Networks products display. Where there are multiple products of the same type, the statistics are
aggregated in one section of the page. To view the traffic and performance statistics of a single device,
click on the device name in the product tree or in the Unit Health pane.
Groups
Synchronizing Settings Across a Group
Applying policies across a group of same-type Barracuda products is perhaps the most powerful
feature of the group context. For example, if you have several Barracuda Web Application Firewalls
grouped and you want to enable Encrypted Cookie Security Mode on all of the devices, you would
do the following:
1.
Click on the group link for those products in the product tree.
2.
Navigate to the BASIC > Default Security page and click on Encrypted for Cookie Security
Mode, then Save Changes. This setting synchronizes across all devices.
3.
To change the value of a setting on just one of the devices, from the product tree, click on the
device itself within the group. You will see the individual product web interface, where you can
navigate to the appropriate page and change the setting as needed. Doing so causes a yellow
Exception ( ) icon to appear in the Group context web interface as described below.
Settings Not Configurable in the Group Context
Some features must be configured on each individual device within a group. Examples include
IP Address, Quarantine settings on the Barracuda Spam Firewall, Services on the Barracuda Web
Application Firewall, and Default Host Name on various product types. Note that some tabs or pages
of the web interface (in the group context) for a product may be grayed out (unavailable) for this
reason, or because the features on that tab or page are not supported in the group context.
Dealing With Exceptions
Exception Triangle
When you are using the group context to view the settings on all devices of one type, if you see the
yellow Exception ( ) icon next to the setting, this means that for a particular setting, the values of
that setting differ across the devices in the group. You can hover the mouse over the setting to see a
text box or table displaying the actual value of the setting on each device.
Managing Products and Groups 25
As shown in Figure 4.3, if you hover the mouse over the exception triangle, the Barracuda Control
Server displays the value of that setting for each product in the group. In this example, each Barracuda
Web Application Firewall in the group has, of course, a different value for the IP Address, each of
which displays in a pop-up table when you hover the mouse over the exception triangle.
Figure 4.3: Exception triangle indicates different values for settings on products of same type
Exception Circle
If you see the round yellow Exception ( ) icon next to a setting, this indicates that the setting is
unique to each device and is not shared or aggregated. For example, suppose you have multiple
Barracuda Web Application Firewalls and you have configured the GET and POST Allowed
Methods for each of them on the Security Policies > URL Protection page. Additionally, you have
configured the HEAD Allowed Method for only one of the devices, so the round Exception icon
displays next to the HEAD Allowed Method indicating that this value is additional and unique to a
particular device. If you hover the mouse over the icon, a pop-up text box displays the device serial
number as shown in Figure 4.4 below.
Figure 4.4: Exception circle indicates a setting unique to one device in a group
In another example, if you have multiple Barracuda Web Application Firewalls in a group, you might
configure an HTTP Service from the BASIC > Services page on all devices, but give each Service a
unique name. The exception circle, as shown in Figure 4.5, indicates that the Service is unique to the
device by Name, even though it’s the same actual Service type (HTTP) as the Services on the other
devices. If an HTTP service with the same Name was configured on each of the devices, you’d see
one entry for the Service and no exception circle.
26
Barracuda Control Server Administrator’s Guide
Figure 4.5: Configuring the same setting type with unique names across a group
Creating Groups
If you want to create a group of a ‘mix’ of different types of Barracuda products:
1.
From the Cloud Control left pane, click Groups, and click Add. Enter a name for the group of
devices. For example, if you want to group multiple types of Barracuda Networks products that
serve the Marketing department, you could name the group MarketingVarious, indicating that
there is more than one type of product in the group.
2.
Next, click on each device you want to add, and drag it to the group name. The screen refreshes
and that device is added to the group. Use the Rename and Delete buttons at the bottom of the
pane to manage groups. Note that deleting a group does NOT disconnect the devices in the
group from the Barracuda Control Server, it just removes the grouping.
Use Case Scenarios
Scenario: Opening a Support Tunnel on Multiple Devices
With the Barracuda Control Server, you can troubleshoot problem devices in a remote location from
your office, or anywhere, by opening a support tunnel on one or more of your Barracuda Networks
products at the same time. Barracuda Networks Technical Support can then assist you with any or all
of the devices connected to your Barracuda Control Server. Using the Barracuda Web Application
Firewall as an example, you click on ADVANCED > Troubleshooting.
Figure 4.6: Barracuda Web Application Firewall: Opening a Support Tunnel
Each Barracuda Web Application Firewall is listed by serial number. If the Action column shows
Open, there is not a support tunnel currently open to the device. Click Open to open a support tunnel.
You can then click Close at any time to close the support tunnel.
Managing Products and Groups 27
Scenario: Synchronizing Firmware and Energize Updates
The Barracuda Control Server provides a fast and convenient method of keeping track of firmware
versions running on all of your Barracuda Networks products. Click Firmwares in the Cloud Control
left pane, and expand the product tree. Each firmware version displays as a separate folder beneath
the device name. Expand the folder to view all devices currently on that firmware version.
To change the firmware version of a device, click on the device name, and click on the ADVANCED >
Firmware Update page. Click Download Now to update the device to the latest firmware release.
To update device definitions, click on the device name, and go to ADVANCED > Energize Updates.
Click Update to update the device to the latest definition, or click Revert to downgrade to the
previous definition version.
Scenario: Applying Policies Across Multiple Barracuda Web Filters
As an administrator of Barracuda Web Filters for a university, you may have two groups of devices;
one group for faculty and staff and another group for students. You want to allow Skype and Yahoo
IM internally for faculty and staff, but not for students.
To configure: Click on the Barracuda Web Filter group assigned to faculty and staff. From the web
interface, you would set Allow for those applications on the BLOCK/ACCEPT > Applications page.
For the Barracuda Web Filters filtering student traffic, you want to block those applications, but allow
Googletalk. Click on the Barracuda Web Filter group assigned to students. From the BLOCK/ACCEPT
> Applications page you can configure these settings for the student group.
Additionally, your IT department may want to push Microsoft updates to student PCs, so, in the
Updates section of the BLOCK/ACCEPT > Applications page, you might set Microsoft Updates to
Block. However, the faculty and staff have admin rights to their PCs - you would set this value to
Allow on that group.
Scenario: Aggregating Reports Across Multiple Products
Suppose you have connected three Barracuda Web Filters to the Barracuda Control Server and you
want to run a report aggregating a list of users by bandwidth across all three devices. You assume all
three devices are up and running. Run the report by clicking on the group of Barracuda Web Filters
from the Cloud Control pane. Select the Users by Bandwidth report from the BASIC > Reports page.
As shown in Figure 4.7 below, for the Barracuda Web Filters listed at the top of the report, an
aggregated list of users shows in the table below the graph, sorted by the user with the most bandwidth
used for the report time frame shown at the top. For more details about reports, see the Barracuda Web
Filter online help on the BASIC > Reports page.
Problem: In the report below, you can see by the highlighted devices that two of the Barracuda Web
Filters have data included in the report, but one of the three devices was unreachable by the Barracuda
Control Server. This is an alert that there might be a power outage or network issue where that device
is located.
Solution: Try logging into the web interface directly for the Barracuda Web Filter that was
unreachable. If you can, then you can use the troubleshooting features on the ADVANCED >
Troubleshooting page for that device, or you can open a support tunnel from the same page and call
Barracuda Networks Technical Support if necessary. If you cannot log in directly from the web
interface, you check the physical device.

Barracuda Control Server Administrator’s Guide
Figure 4.7: Data aggregated across multiple Barracuda Web Filters
Scenario: Synchronizing Security Policies Across Products
You have four Barracuda Web Application Firewalls serving three locations: New York, San
Francisco and London. Your master Security Policies database dictates that all devices should have
the HttpOnly attribute set to Yes for cookies, preventing the cookie from being accessed by
client-side scripts.
To Configure: Click on the group of Barracuda Web Application Firewalls from the Cloud Control
pane and check the SECURITY POLICIES > Cookie Security page. An exception triangle for this
setting may display, as shown below, if the devices are not in sync for this setting. Hover the mouse
over the setting to view the values for Http Only on each device in the pop-up table:
Figure 4.8: Exception shows different values for a setting across a group of devices
Resolving an Exception: To resolve the issue, click on the NYC and London Web Application
Firewalls, successively, in the product tree, and change the settings to match those of the two San
Francisco systems. Once you save those settings, the exception triangle no longer appears next to the
setting when viewed in the Group context.

Open Source Licensing
Barracuda products may include programs that are covered by the GNU General Public License
(GPL) or other “open source” license agreements. The GNU license is re-printed below for you
reference. These programs are copyrighted by their authors or other parties, and the authors and
copyright holders disclaim any warranty for such programs. Other programs are copyright by
Barracuda Networks.
GNU GENERAL PUBLIC LICENSE, (GPL) Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing
it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it.
contrast, the GNU General Public
By
License is intended to guarantee your freedom to share and change free software--to make sure the
software is free for all its users. This General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to using it. (Some other Free
Software Foundation software is covered by the GNU Library General Public License instead.) You can
apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses
are designed to make sure that you have the freedom to distribute copies of free software (and charge
for this service if you wish), that you receive source code or can get it if you want it, that you can
change the software or use pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or
to ask you to surrender the rights. These restrictions translate to certain responsibilities for you
if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whethergratis or for a fee, you must give the
recipients all the rights that you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which
gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that
there is no warranty for this free software. If the software is modified by someone else and passed
on, we want its recipients to know that what they have is not the original, so that any problems
introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger
that redistributors of a free program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any patent must be licensed for
everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright
holder saying it may be distributed under the terms of this General Public License. The "Program",
below, refers to any such program or work, and a "work based on the Program" means either the Program
or any derivative work under copyright law: that is to say, a work containing the Program or a portion
of it, either verbatim or with modifications and/or translated into another language. (Hereinafter,
translation is included without limitation in the term "modification".) Each licensee is addressed
as "you".
Activities other than copying, distribution and modification are not covered by this License; they are
outside its scope. The act of running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the Program (independent of having been
made by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any
medium, provided that you conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License
and to the absence of any warranty; and give any other recipients of the Program a copy of this
License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based
on the Program, and copy and distribute such modifications or work under the terms of Section 1 above,
provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files
and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or
is derived from the Program or any part thereof, to be licensed as a whole at no charge to all
third parties under the terms of this License.
Limited Warranty and License 41
c) If the modified program normally reads commands interactively when run, you must cause it,
when started running for such interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice that there is no warranty (or
else, saying that you provide a warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this License. (Exception: if the Program
itself is interactive but does not normally print such an announcement, your work based on the
Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are
not derived from the Program, and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those sections when you distribute them
as separate works. But when you distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of this License, whose permissions
for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written
entirely by you; rather, the intent is to exercise the right to control the distribution of derivative
or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a
work based on the Program) on a volume of a storage or distribution medium does not bring the other
work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or
executable form under the terms of Sections 1 and 2 above provided that you also do one of the
following:
a) Accompany it with the complete corresponding machine-readable source code, which must be
distributed under the terms of Sections 1 and 2 above on a medium customarily used for software
interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for
a charge no more than your cost of physically performing source distribution, a complete machinereadable copy of the corresponding source code, to be distributed under the terms of Sections 1 and
2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding
source code. (This alternative is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such an offer, in accord with Subsection
b above.)
The source code for a work means the preferred form of the work for making modifications to it. For
an executable work, complete source code means all the source code for all modules it contains, plus
any associated interface definition files, plus the scripts used to control compilation and
installation of the executable. However, as a special exception, the source code distributed need not
include anything that is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on which the executable runs, unless
that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not compelled to copy the source along
with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under
this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void,
and will automatically terminate your rights under this License. However, parties who have received
copies, or rights, from you under this License will not have their licenses terminated so long as
such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Program or its derivative works. These actions
are prohibited by law if you do not accept this License. Therefore, by modifying or distributing
the Program (or any work based on the Program), you indicate your acceptance of this License to do
so, and all its terms and conditions for copying, distributing or modifying the Program or works
based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient
automatically receives a license from the original licensor to copy, distribute or modify the Program
subject to these terms and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing compliance by third
parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other
reason (not limited to patent issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this License, they do not excuse you from
the conditions of this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as a consequence you may
not distribute the Program at all. For example, if a patent license would not permit royalty-free
redistribution of the Program by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would be to refrain entirely from
distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right
claims or to contest validity of any such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software distributed through that
system in reliance on consistent application of that system; it is up to the author/donor to decide
42
Barracuda Control Server Administrator’s Guide
if he or she is willing to distribute software through any other system and a licensee cannot impose
that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of
this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents
or by copyrighted interfaces, the original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded. In such case, this License
incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License
from time to time. Such new versions will be similar in spirit to the present version, but may differ
in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of
this License which applies to it and "any later version", you have the option of following the terms
and conditions either of that version or of any later version published by the Free Software Foundation.
If the Program does not specify a version number of this License, you may choose any version ever
published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution
conditions are different, write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT
PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER,
OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO
YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF
THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion
of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
one line to give the program's name and an idea of what it does.
Copyright (C) yyyy
name of author
This program is free software; you can redistribute it and/or modify it under the terms of the GNU
General Public License as published by the Free Software Foundation; either version 2 of the License,
or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even
the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General
Public License for more details.
You should have received a copy of the GNU General Public License along with this program; if not,
write to the Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO
WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use
may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary.
Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes
passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public
License instead of this License.

(except as stated in this section) patent license to make, have made, use, offer to sell, sell, import,
and otherwise transfer the Work, where such license applies only to those patent claims licensable by
such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of
their Contribution(s) with the Work to which such Contribution(s) was submitted. If You institute
patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging
that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent

The contents of the NOTICE file are for informational purposes only and do not modify the License. You
may add Your own attribution notices within Derivative Works that You distribute, alongside or as an
addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot
be construed as modifying the License.
You may add Your own copyright statement to Your modifications and may provide additional or different
license terms and conditions for use, reproduction, or distribution of Your modifications, or for any
such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work
otherwise complies with the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally
submitted for inclusion in the Work by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions. Notwithstanding the above, nothing herein

result of this License or out of the use or inability to use the Work (including but not limited to
damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other
commercial damages or losses), even if such Contributor has been advised of the possibility of such
damages.
9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works
thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this License. However, in accepting such
obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any
other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for
any liability incurred by, or claims asserted against, such Contributor by reason of your accepting
any such warranty or additional liability.
