What is NVC?
-----------------------------------------------------------------------
Norman Virus Control (NVC) is an anti-virus program that scans your
computer for malicious software, also referred to as malware.
Malware is viruses, worms, and other varieties of destructive code.
NVC can detect and remove known and unknown viruses from hard disks,
floppy disks, and e-mail attachments (see "Interfacing NVC with mail
programs").




Obtaining software and documentation
-----------------------------------------------------------------------
Latest version of NVC for Linux is available at:
http://www.norman.com/Download/Full_versions

Manuals can be downloaded from :
http://www.norman.com/manuals.shtml




System requirements
-----------------------------------------------------------------------
NVC for Linux requires the following :

- i386 or compatible architecture
- a working Linux installation with:
- glibc 2.2 or better
- X server for configuration
- Java 1.4 for configuration





Installation, update and removal
-----------------------------------------------------------------------
NVC for Linux is available in three different package formats:

RPM for RedHat, Mandrake, SuSE and other RPM-based distributions.
DEB for Debian, Skolelinux, Lindows and other DPKG-based distributions.
TGZ for Slackware, gentoo and other source-based distributions.

NVC for Linux will install itself to the /opt/norman directory and make
symbolic links to all executable components in /usr/bin. You need
sufficient rights to install NVC for Linux, such as root.

The following components are sym-linked :

nvcoa - On-access scanner
nvcc - Command line scanner
niucf - Internet Update Configuration
nvccf - Main configuration tool
niu - Internet Update


Log files :
If run as root       - /opt/norman/logs/
If run as a regular user - $HOME/.norman/logs
   

RPM :
-----
Go to the directory which contains the RPM file and type the following:

rpm -i nvcc-x.xx-xx.rpm

To remove NVC for Linux type the following:

rpm -e nvcc

DEB :
-----
Go to the directory which contains the DEB file and type the following:

dpkg -i nvcc-x.xx-xx.deb

To remove NVC for Linux type the following:

dpkg -r nvcc

TGZ :
-----
Move the .tgz file to /. and type the following

tar xvzfp ./nvcc-x.xx-x.tgz

Run the program 'install.sh' to set up symbolic links

/opt/norman/nvc/bin/install.sh

To remove NVC for Linux you should type the following:

/opt/norman/nvc/bin/uninstall.sh


Completing the installation (all packages) :
--------------------------------------------
After installing NVC for Linux you must perform the following steps
to complete the installation :

- Run 'nvccf' and insert your authentication key under
  the "Authentication" tab.
  alternatively you can supply license information with the
  --key argument to nvccf

- Run 'niucf' and select all applicable options. niucf is
  optional for single user installations
 
- Run 'niu' to update the installation

** NOTE WELL **
niucf is only needed if you want NVC for Linux to maintain a
distributed NVC installation. Please see NVC's "Administrator's
Guide" for further information.





Components
-----------------------------------------------------------------------

nvcc (console)
--------------
nvcc is the actual command line scanner. Run with --help for more
information about the different arguments.

Example :

nvcc -s -u -cl /

The line above will check the entire filesystem and clean without prompting
for what action to take.

Example :

nvcc -s -u -cl /home/johndoe

The line above will check the directory /home/johndoe and all
subdirectories and clean without prompting for what action to take.


Also note that nvcc does not follow symlinks unless specified.


NIU (console)
-------------
NIU is responsible for the actual updating of NVC for Linux. NIU will
extract the information needed from the files 'niucf.ndf' and
'nvccf.ndf' made with 'niucf' and 'nvccf'.

Run with --help for more information about the different arguments.


niucf (java dependant)
----------------------
niucf is used to configure updating of a network-distributed NVC,
including distribution to Windows platforms. Please see the
NVC's "Administrator’s Guide" for further information.


nvccf (java dependant)
----------------------
nvccf is used primarily for entering data applicable to network
distributions and is similar to the "Configuration Editor" found
in NVC for other platforms. Please see NVC's "Reference Guide" or
"Administrator's Guide" for detailed information.





Interfacing NVC with mail servers
-----------------------------------------------------------------------
NVC for Linux is compatible with recent versions of the AMaViS wrapper,
and can therefore be interfaced with all major mail daemons (MTAs)
such as sendmail, postfix, qmail and exim.

AMaViS is available from <a class="postlink" href="http://www.amavis.org">http://www.amavis.org</a>




Recommended additions to NVC for Linux
-----------------------------------------------------------------------
An on-access scanner is also under development, and is scheduled for
release in Q1 2004.

Lars skrev: Om .deb-filen inte fungerar så kan det bero på att den är anpassad för Debian och inte Ubuntu. Ladda ner .tgz-filen istället och gör så här:

Kod: Markera allt

Lars skrev: Aha, de antar att förmodligen att /bin/sh är samma sak som /bin/bash, det stämmer på många Linux-system men inte på Ubuntu. Gå in och ändra översta raden till /bin/bash istället för /bin/sh.
