<I>freshclam</I> is a tool, which automates the virus database update
process for Clam AntiVirus. You will find more information about it in
the section <A HREF="node20.html#freshclam">3.5</A>. It may be used in two ways:
<UL>
<LI>interactive - from command line
</LI>
<LI>as a daemon - works alone, silently
</LI>
</UL>
<B>Run <I>freshclam</I> (as root) without any parameters to check
is it working correctly</B>. If everything is OK, create a log file in
/var/log owned by <I>clamav</I>:
<PRE>
# touch /var/log/clam-update.log
# chmod 644 /var/log/clam-update.log
# chown clamav /var/log/clam-update.log
</PRE>
Now, you may run <I>freshclam</I> as a daemon:
<PRE>
# freshclam -d -c 2 -l /var/log/clam-update.log
</PRE>
It will check for a new database 2 times a day. Please add this line
to your startup scripts. The other way is to use the <I>cron</I> daemon.
You have to add a similar line to the crontab of <B>root</B> or
<B>clamav</B>:
<FONT SIZE="-1"> </FONT><PRE>
0 8 * * * /usr/local/bin/freshclam --quiet -l /var/log/clam-update.log
</PRE>
It will check for a new database daily at 8 am. You may need
to setup the proxy support on your system. You should set the environment
variable <I>$http_proxy</I>, eg.
<PRE>
export http_proxy="my.proxy.server:8080"
</PRE>
There is also <I>-http-proxy</I> option available.
