<code>freshclam</code> is the default database updater for Clam AntiVirus.
It can work in two modes:
<UL>
<LI>interactive - from command line, verbosely
</LI>
<LI>daemon - alone, silently
</LI>
</UL>
When started by a superuser it drops privileges and switches
to the <I>clamav</I> user. <code>freshclam</code> uses the
<TT><A NAME="tex2html32"
HREF="database.clamav.net">database.clamav.net</A></TT> round-robin DNS which automatically selects |
| 5638b256 |
a database mirror<A HREF="node148.html#mirrors">9.1</A>. <code>freshclam</code> is an advanced tool: |
| a907fb08 |
it supports database version verification through DNS, proxy servers (with
authentication), digital signatures and various error scenarios.
<B>Quick test: run freshclam (as superuser) with no parameters
and check the output.</B> If everything is OK you may create the log file in
/var/log (owned by <I>clamav</I> or another user <code>freshclam</code> will be
running as (<code>--user</code>):
<PRE> |
| 5638b256 |
# touch /var/log/freshclam.log
# chmod 600 /var/log/freshclam.log
# chown clamav /var/log/freshclam.log |
| a907fb08 |
</PRE>
Now you <I>should</I> edit the configuration file (<code>freshclam.conf</code> or
<code>clamd.conf</code> if they're merged) and configure the
<I>UpdateLogFile</I> directive to point to the created log file.
Finally, to run <code>freshclam</code> in the daemon mode, execute:
<PRE>
# freshclam -d
</PRE>
The other method is to use the <I>cron</I> daemon. You have to add the
following line to the crontab of the <B>root</B> or <B>clamav</B> users:
<FONT SIZE="-1"> </FONT><PRE>
N * * * * /usr/local/bin/freshclam --quiet
</PRE>
to check for a new database every hour. <B>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.</B>
Proxy settings are only configurable via the configuration file and
<code>freshclam</code> will require strict permissions on the config file when
<code>HTTPProxyPassword</code> is enabled.
<PRE>
HTTPProxyServer myproxyserver.com
HTTPProxyPort 1234
HTTPProxyUsername myusername
HTTPProxyPassword mypass
</PRE>
