freshclam: Setting up auto-updating</A>
|
|
</H2>
|
|
<SPAN CLASS="textit">freshclam</SPAN> is a default database updater for Clam AntiVirus.
|
|
It can work in two modes:
|
|
|
|
<UL>
|
|
<LI>interactive - from command line, verbosly
|
|
</LI>
|
|
<LI>daemon - alone, silently
|
|
|
|
</LI>
|
|
</UL>
|
|
When started by a superuser (by default) it drops privileges and switches
|
|
to the <SPAN CLASS="textit">clamav</SPAN> user. <SPAN CLASS="textit">freshclam</SPAN> uses the
|
|
<TT><A NAME="tex2html21"
|
|
HREF="database.clamav.net">database.clamav.net</A></TT> round-robin DNS which automatically selects
|
|
a database mirror<A HREF="node17.html#mirrors">2.11</A>. freshclam is an advanced tool: supports
|
|
proxy servers (with authentication), digital signature verification and
|
|
various error scenarios. <SPAN CLASS="textbf">Quick test: run <SPAN CLASS="textit">freshclam</SPAN> (as
|
|
superuser) with no parameters and check the output.</SPAN> If everything
|
|
is OK you may create the log file in /var/log (owned by <SPAN CLASS="textit">clamav</SPAN> or
|
|
another user freshclam will be running as (<code>--user</code>):
|
|
<PRE>
|
|
# touch /var/log/clam-update.log
|
|
# chmod 600 /var/log/clam-update.log
|
|
# chown clamav /var/log/clam-update.log
|
|
</PRE>
|
|
Now you <SPAN CLASS="textit">should</SPAN> edit the configuration file (usually
|
|
<SPAN CLASS="textit">freshclam.conf</SPAN>) and configure the <SPAN CLASS="textit">UpdateLogFile</SPAN> directive
|
|
to point the created log file (it's highly recommended). Optionally you
|
|
may force the log file path with <SPAN CLASS="textit">-l</SPAN>. Finally, to run freshclam
|
|
in the daemon mode execute:
|
|
<PRE>
|
|
# freshclam -d
|
|
</PRE>
|
|
The other method is to use the <SPAN CLASS="textit">cron</SPAN> daemon. You have to add the
|
|
following line to the crontab of the <SPAN CLASS="textbf">root</SPAN> or <SPAN CLASS="textbf">clamav</SPAN> users:
|
|
<SMALL CLASS="SMALL"> </SMALL><PRE>
|
|
N * * * * /usr/local/bin/freshclam --quiet
|
|
</PRE>
|
|
to check for a new database every hour. <SPAN CLASS="textbf">N should be a
|
|
number between 1 and 59 of your choice. Please don't choose any multiple
|
|
of 10, because there are already too many servers using those time slots.</SPAN>
|
|
Proxy settings are only configurable via the configuration file (so you
|
|
can setup proper permissions to protect your proxy password):
|
|
<PRE>
|
|
HTTPProxyServer myproxyserver.com
|
|
HTTPProxyPort 1234
|
|
HTTPProxyUsername myusername
|
|
HTTPProxyPassword mypass
|
|
</PRE>
|
|
|
|
