in the local mirror directory and is used as a reference file for generation of further subordinate
mirrors. The process of subordinate mirror creation is described in the section 6.2 in detail.
6.1.2. NOD32 mirror creation
As has already been told, NOD32 update mirror creator (nod32umc) utility is used to download
and maintain the mirror of NOD32 modules storage. Minimal nod32umc configuration requires
that you define authentication options and the absolute path to the directory where the mirror
will be created.
Authentication options are used to pass to nod32umc the username and password (received
from vendor) necessary to authenticate the end-user against NOD32 server where the modules
are downloaded from. Several scenarios for user authentication against NOD32 server are sup-
ported:
• direct username and password setting into the command line.
• setting via an authentication file,
• setting via an old featured ’.netrc’ file.
Please refer also to the nod32umc manual pages for a detailed description of the related com-
mand line options.
After proper authentication the modules will be downloaded into a defined mirror directory.
There exists also the possibility to download and update NOD32 modules in the situation where
all the communication of the local computer with the NOD32 server is mediated via http proxy
server. Read more on this topic in nod32umc manual pages. In situations when user authenti-
cation is required against the appropriate proxy server, the minimal nod32umc configuration
must include also the proxy authentication options. There are two supported scenarios for user
authentication against proxy server:
• direct proxy username and proxy password setting into the command line
• setting via a proxy authentication file.
Please, refer also to the nod32umc manual pages for a detailed description of the related com-
mand line options.
Note: For security reasons, please use authentication scenarios via authentication files rather
than scenarios via typing the username(s) and password(s) directly into the command line.
6.1.3. Generation of NOD32 scanner loading modules
In order to create loading modules from those downloaded by nod32umc one must use the
NOD32 Update (nod32upd) system utility (see also nod32upd manual pages). Minimal con-
figuration for nod32upd is to define full mirror directory path. The following NOD32 load-
ing modules will be created: base module (nod32.000), archives support module (nod32.002),
advanced heuristics module (nod32.003) and packed worm scanner module (nod32.004). One
could specify the directory path where the loading module would be created (so called NOD32
