AVG Linux Email Server / User Manual

7.3. On-access Scanner

The DAZUKO kernel interface for file access control must be inserted as a module

into your kernel in order to enable the on-access scanning using the AVG for Linux

E-mail Server engine. You can download the latest version of DAZUKO at

http://www.dazuko.org. It is recommended to download the latest version available

especially if you are running the kernel of major version 2.6 (or higher)!

To install the DAZUKO kernel module, follow these instructions:

a) Get your Kernel Source Code

It is highly recommended to build and install a kernel from the actual kernel

sources first. Then it is certain that the kernel source code you use to build

DAZUKO matches the running kernel. Many Linux distributions provide

packages with the kernel source code. If you do not plan building a completely

new customized kernel, make sure you install the proper kernel source

packages for your distribution.

Note: If you do not have any experience with building the Linux kernel, you

should not attempt to install DAZUKO unless you get some information and

practice in hacking the Linux kernel internals!

b) Compile DAZUKO

Once the source code for your running kernel is available, you can build

DAZUKO. You can download the latest version of DAZUKO at

http://www.dazuko.org. Unpack the downloaded file using the

$ tar –xvzf dazuko-{version}.tar.gz

command and switch to the unpacked directory.

Edit the

configure file and change the 0 value to 1 for the

ON_CLOSE_MODIFIED parameter in the MAIN section. Generate a

Makefile

by running the

$ ./configure

command in the directory with the DAZUKO source files. This will determine

the features of your system needing to be specified in the generated Makefile.

Then you can compile DAZUKO with the

$ make

command. This will create the device driver as well as a couple of example

programs. Under Linux 2.2-2.4 the device driver is named

dazuko.o. Under

Linux 2.6 it is named

dazuko.ko.

c) Insert DAZUKO

Having compiled DAZUKO successfully, the final step is to insert the module

into the kernel.
