of the NOD32LFS/NOD32BFS product and thus it must be compiled and installed into the kernel prior the NOD32 on- access scanner (nod32dac daemon) initialization. On the other hand the Dazuko technique make on-access scanning independent of used file system type. It is also suitable for controlling file system objects via Network File System (NFS), Nettalk and Samba. -
Page 14: Installation And Configuration
4.2.1.2. Installation and configuration It has been already discussed that prior any ‘nod32dac’ initialization, so-called Dazuko kernel module has to be compiled and installed within the running kernel. Note that the following text contains only brief description of the Dazuko kernel module installation. Therefore it is highly recommended to read the Dazuko how-to-install documentation (see http://www.dazuko.org/howto-install.shtml) in order to compile and load the Dazuko module properly into the kernel. -

Page 16: On-Access Scanner Using Preload Libc Library
4.2.2.1. Operation principle On-access scanner ‘libnod32pac.so’ (NOD32 Preload library based file Access Controller) is a shared objects library that is used as a preload library of LIBC and can become functional during the system start-up. It is thus applicable for file system servers using LIBC calls, for instance ftp server, Samba server etc. - Page 17 responsible for initialization of smbd daemon by the following line LD_PRELOAD=/usr/lib/libnod32pac.so daemon /usr/sbin/smbd $SMBDOPTIONS In this manner selected file system objects controlled by Samba will be checked immediately after Samba initialization, i.e. during the system start-up. chapter 4 / Integration with Linux/BSD File System...
