<code>freshclam</code> is the automatic database update tool for Clam AntiVirus.
|
|
It can work in two modes:
|
|
|
|
<UL>
|
|
<LI>interactive - on demand from command line
|
|
</LI>
|
|
<LI>daemon - silently in the background
|
|
|
|
</LI>
|
|
</UL>
|
|
<code>freshclam</code> is advanced tool: it supports scripted updates (instead
|
|
of transferring the whole CVD file at each update it only transfers the
|
|
differences between the latest and the current database via a special
|
|
script), database version checks through DNS, proxy servers (with
|
|
authentication), digital signatures and various error scenarios.
|
|
<SPAN CLASS="textbf">Quick test: run freshclam (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 <code>freshclam</code> will be
|
|
running as):
|
|
<PRE>
|
|
# touch /var/log/freshclam.log
|
|
# chmod 600 /var/log/freshclam.log
|
|
# chown clamav /var/log/freshclam.log
|
|
</PRE>
|
|
Now you <SPAN CLASS="textit">should</SPAN> edit the configuration file <code>freshclam.conf</code>
|
|
and point the <SPAN CLASS="textit">UpdateLogFile</SPAN> directive to the log file. Finally, to
|
|
run <code>freshclam</code> in the daemon mode, execute:
|
|
<PRE>
|
|
# freshclam -d
|
|
</PRE>
|
|
The other way is to use the <SPAN CLASS="textit">cron</SPAN> daemon. You have to add the
|
|
following line to the crontab of <SPAN CLASS="textbf">root</SPAN> or <SPAN CLASS="textbf">clamav</SPAN> user:
|
|
<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 3 and 57 of your choice. Please don't choose any multiple
|
|
of 10, because there are already too many clients using those time slots.</SPAN>
|
|
Proxy settings are only configurable via the configuration file and
|
|
<code>freshclam</code> will require strict permission settings for the config
|
|
file when <code>HTTPProxyPassword</code> is turned on.
|
|
<PRE>
|
|
HTTPProxyServer myproxyserver.com
|
|
HTTPProxyPort 1234
|
|
HTTPProxyUsername myusername
|
|
HTTPProxyPassword mypass
|
|
</PRE>
