CHAPTER 1. INTRODUCTION
The constant growth in the number of computer users and new the possibilities
of data exchange between them via e-mail or internet result in the increased
threat of virus infections and data corruption or theft by malicious computer
programs.
Among the sources of malware penetrating users’ computers the most
dangerous are:
Internet
Global information network is the main source of distribution of all types of
malware. As a rule, viruses and other malicious programs are be located
on popular internet websites disguising themselves as useful software or
freeware. Malware can be located within numerous scripts that automati-
cally run when a website is loaded in the user’s browser.
E-mail messages
E-mail messages delivered to the user’s mailbox and stored in the e-mail
databases may contain viruses. Malware can be located either in the at-
tachments to messages or in the body of a message. As a rule, infected
e-mail messages contain viruses or mail worms. When you open an e-
mail message or save an attached file to your hard drive, you may infect
data stored in your computer.
Software vulnerabilities
In most cases hackers’ attacks are attempted using "software holes".
Such vulnerabilities allow hackers to obtain remote access to your com-
puter and, therefore, to your data, your LAN resources and other sources
of information.
In the Unix-based systems viruses are far less common compared, for example,
to the Windows Operating System due to the peculiarities of the two platforms.
However, this does not mean that Unix users encounter no threat. Provided
below is a detailed description of malware types.
1.1. Computer viruses and malware
In order to be aware of the potential threats to your computer, it is helpful to know
what the types of malicious software (“malware”) are and how they work. In
general, malicious programs fall into one of the following three categories:
Worms – malicious programs that belong to this category use network
resources for distribution. These programs were called "worms" due to
their ability to tunnel from one computer to another, using networks, email

6 Introduction
and other channels. Due to this ability, worms can proliferate extremely
fast.
Worms penetrate a computer, determine IP addresses of other com-
puters, and send copies of themselves to these computers. Apart from the
network addresses, worms often use data contained in the address books
of e-mail client applications installed on the infected machine. Sometimes
worms create work files on disks, but they also can function without utiliz-
ing any resources of the infected computer except RAM.
Viruses –programs that infect other programs by adding their code to the
infected program's code in order to gain control when infected files are
run. This simple definition helps determine that the major action a virus
performs is infecting computer programs. Viruses spread somewhat
slower than worms.
Trojan horses or Trojans – perform unauthorized actions on infected
computers, for instance, depending on the particular conditions, they can
erase information on hard drives, "freeze" the system, steal confidential
information, etc. In the strict sense, Trojan Horses are not viruses as they
do not infect programs or data; they are unable to sneak independently
into computers and therefore are distributed by impostors disguised as
some "useful" software. However, Trojans may inflict far greater damages
compared to a regular virus attack.
Recently, worms and Trojans have become the most widespread type of
malware in the Unix-based systems.
Henceforth in the text of this Guide the term "virus" will be used to refer
to viruses, Trojan Horses and worms. A particular type of malware will
be mentioned only when it is required.
1.2. The purpose and main features
of Kaspersky Anti-Virus
Kaspersky Anti-Virus®5.5 for Samba Servers software application (hereinafter
also called Kaspersky Anti-Virus) performs anti-virus scanning of objects for
Samba servers running Linux or FreeBSD operating systems.
The application accomplishes two-level scanning of server file systems both in
real-time and in the on-demand scanning mode. If malicious code is detected
Kaspersky Anti-Virus can cure or block the infected objects efficiently in order to
prevent further spreading of epidemics providing timely notifications to system
administrators about such accidents.

Introduction 7
The application also employs iChecker™ – an intellectual technology,
which allows considerable increase of file scanning speed.
Kaspersky Anti-Virus for Samba Servers is a package of anti-virus components
performing the following functions:
•Real-time protection of Samba file server from malicious code (On-
Access Scanner).
•On-demand searching and neutralization of malicious code in the
server file system (On-Demand Scanner).
•Notifications to the administrator about detection of infected or sus-
picious objects.
•Maintaining the current status of the anti-virus databases
(keepup2date).
•Local and remote administration using a web administration module
(Webmin).
Besides, Kaspersky Anti-Virus offers the following additional functionality to its
users:
•An opportunity to run user-defined scripts in cases, when events of
the “an infected file was detected” type occur.
•An opportunity to move infected (or suspicious) objects to a special
storage location (quarantine).
•Preserving the original infected object prior to its disinfection
(Backup) with an opportunity to restore it in a non-standard situa-
tion.
•Saving information about already scanned files in an operational
cache, which allows a considerable increase of file scanning speed
during subsequent access to such files (the cache preserves the in-
formation until application restart).
•An opportunity to restrict the maximum number of files for simulta-
neous real-time scanning while adding the rest of the requested
files to a scanning queue.
•An opportunity to suspend automatically the anti-virus background
file scanning, when the server load exceeds the user-defined level –
and resume operation, when the server load reaches an acceptable
level.
•An opportunity to define any combination of “scanning on access”
and “scanning on saving” modes for each public directory.
•An opportunity to define selectively individual anti-virus protection
settings for each public directory.

8 Introduction
•The least loaded updates’ server of Kaspersky Lab is detected dur-
ing the updating of the anti-virus databases. Besides, in cases of
line disconnection the updating process after reconnection resumes
its work from the place where it left off.
•An opportunity to roll back both the updates to anti-virus databases
and application updates.
1.3. Hardware and software system
requirements
Operation of Kaspersky Anti-Virus for Samba Servers requires:
•Intel Pentium®133 MHz CPU or better.
•64 МB RAM.
•100 MB of disk space for application installation and storage of temporary
files.

CHAPTER 2. INTERNAL
ARCHITECTURE OF
KASPERSKY ANTI-VIRUS
FOR SAMBA SERVERS
Before we describe the features of Kaspersky Anti-Virus for Samba Servers let
us discuss its internal architecture in detail. That will allow better understanding
of the Anti-Virus operation algorithm.
2.1. Component structure
Kaspersky Anti-Virus for Samba Servers consists of the following components:
•kavsamba (or an On-Access Scanner);
•kavscanner (or an On-Demand Scanner);
•keepup2date.
The kavsamba component, in its turn, includes the kavsamba.so and kavsamba
modules. The kavsamba.so is implemented in the form of a dynamic library
integrated into Samba server and intercepting attempts to access files through
that Samba server. The kavsamba module is a daemon process analyzing the
files provided by the kavsamba.so files and processing them in accordance with
the current settings. Data exchange between the module and the daemon
process is accomplished through a local socket (Unix Domain sockets).
The kavscanner component is designed for anti-virus protection of file systems.
Server file systems or individual directories are scanned according to the
administrator’s demand or the schedule (depending upon selected settings).
The keepup2date component updates the anti-virus databases used during
scanning and disinfection and also downloads patches to the package programs.
2.2. Algorithm of operation
Here we shall review internal architecture of the product in terms of real-time
anti-virus protection since the on-demand scanning process is fairly simple and
does not require any special coverage.
So the used algorithm of operation is as follows:

Internal architecture of Kaspersky Anti-Virus for Samba Servers 13
1. If a user attempts to access a file through Samba server the request
is intercepted by the server itself and transferred to the
kavsamba.so module.
2. The kavsamba.so module sends the data pertaining to the request
(file name, its full path, ID of the user who requested the file,
computer domain name) to the kavsamba component through IPC
using binary protocol.
3. The kavsamba module scans the requested object for viruses and
processes it in accordance with the settings in the configuration file
(including the use of anti-virus databases, if that option is enabled).
4. Upon completion of file scanning and processing kavsamba.so
receives from kavsamba the access code (granted/denied), which
determines the file status.
5. In accordance with the object status kavsamba.so transfers to the
Samba server a permit to access the object or blocks the latter.
Access to a file is blocked if the latter is infected or looks suspicious (Infected,
CureFailed, Warning, Suspicion). In all other cases access to the file is granted.

CHAPTER 3. INSTALLATION OF
KASPERSKY ANTI-VIRUS
Prior to beginning the installation of Kaspersky Anti-Virus we recommend the
following preparations for your system:
•Make sure that your system conforms to the hardware and software re-
quirements for installation of the Kaspersky Anti-Virus (please see sec-
tion 1.3 on p. 7).
•Enter the system as superuser (root).
3.1. Software installation to a server
running Linux
Kaspersky Anti-Virus for computers running Linux is distributed in two variants of
installation packages:
•.rpm – for systems that support RPM Package Manager.
•.deb – for Debian Linux distributions.
In order to start the installation of Kaspersky Anti-Virus from an .rpm
package enter the following in the command line:
rpm –i <package_file_name>
In order to start the installation of Kaspersky Anti-Virus from a .deb
package enter the following in the command line:
dpkg –i <package_file_name>
3.2. Software installation to a server
running FreeBSD
The installation package of Kaspersky Anti-Virus is supplied in a pkg package for
servers running FreeBSD operating system.
In order to start the installation of Kaspersky Anti-Virus from a pkg
package enter the following in the command line:

Installation of Kaspersky Anti-Virus 15
pkg_add <package_name>
3.3. Installation process
For several reasons the process of installation may terminate with an
error code. In such cases make sure that your computer conforms to
the hardware and software requirements (please see section 1.3 on
p. 7) and that you have logged into the system with root privileges.
The application is installed to a server in several stages:
1. Copying the installation package files to a server.
2. Configuration of the keepup2date component.
3. Installation (updating) of the anti-virus databases.
Ensure that the anti-virus databases are installed before you begin
using the product. The procedure of anti-virus scanning and disin-
fection depends upon the records in the anti-virus databases con-
taining descriptions of all currently known viruses and cure meth-
ods for infected objects. Scanning and processing of files cannot
be performed without anti-virus databases!
Please note also that automatic configuration of the application will
not be performed if the anti-virus databases are not installed.
4. License key installation.
If a license key is not installed, configuration will not be performed
and it will be impossible to use the application. However, if the key
is missing temporarily (for example, the product has been pur-
chased via the Internet and the license key hasn’t been received by
e-mail yet) you can install it after installation, before beginning to
actually use the product.
5. Installation of a Webmin module.
Remote control module for the Webmin package will be installed
only if Webmin has a standard path. After module installation you
will receive respective recommendations for its setup to work with
the application.
3.4. Configuring the application
System configuration is performed immediately upon copying the installation
package files to server. Depending upon the package manager the configuration
stage will either start automatically or (if the package manager does not allow
using interactive packages like .rpm, for example) require some additional

16 Introduction
actions on the user’s part. A respective message will appear on-screen in that
case.
The process of configuring the application consists of the following stages:
•Search for an installed Samba server and checking its version for confor-
mity with the software requirements.
•Search and modification of the Samba server configuration file.
•Checking the Samba server configuration file for presence of VFS ob-
jects. If the Samba server configuration file contains lines indicating VFS
objects in use, they will be commented.
If you are using FreeBSD with Samba server versions 3.0-3.0.9,
incorrect handling of VFS modules is possible because of certain
specific peculiarities of the operating system.
To ensure proper interaction between the application and VFS ob-
jects, you are advised to upgrade your Samba server version or
install a patch for Samba server (please see
https://bugzilla.samba.org/show_bug.cgi?id=2100 for details about
the patch).
If the system configuration requires some additional information (e.g., the path to
the Samba server configuration file) the respective questions will be output to
server console. Entry of incorrect responses will abort the configuration process.
If the above configuration stages complete successfully, the application will be
ready for work, no additional notifications will be produced. The configuration file
supplied with the product package contains all settings necessary to start
working.
Please keep in mind that you have to restart the Samba server before
you can proceed to further work.
3.5. Locations of product files
After Kaspersky Anti-Virus installation its files will be placed in the following
locations (provided that all default paths suggested during the procedure are
accepted):
In Linux:
/etc/opt/kaspersky/ – the directory containing the configuration file of Kaspersky
Anti-Virus and other files with various settings:

Installation of Kaspersky Anti-Virus 19
3.6. Upgrading your Samba server
The distribution package of Kaspersky Anti-Virus contains binary VFS
modules for supported Samba versions.
If you have a new Samba Server version unsupported by Kaspersky
Anti-Virus, you can rebuild the VFS module of the application manually.
In order to do that perform the following steps:
If you are running Linux, enter the following in the command line:
cd /opt/kaspersky/kav4samba/src
./configure --with-sambasrc=<path_to_samba>
&& make
where <path_to_samba> stands for the path to the source code of the
Samba Server modules.
If you are running FreeBSD, enter the following in the command
line:
cd /usr/local/src/kav4samba
./configure --with-sambasrc=<path_to_samba> && make
where <path_to_samba> stands for the path to the source code of
the Samba Server modules.
An updated version of the VFS module will be created in the /lib subdirectory.
The administrator will have to configure and install the module then.
3.7. Uninstalling Kaspersky Anti-
Virus
The procedure of uninstalling Kaspersky Anti-Virus for Samba Servers requires
the following:
•Superuser privileges (root or another user with UID=0). If you have no
such privileges at the moment of uninstall procedure you’ll have to enter
the system as root.
•Stopped Samba server.
The uninstaller routine does not stop the Samba server on its
own!
