Clamuko
</H2>
Clamuko is a special thread in <code>clamd</code> that performs on-access
scanning under Linux and FreeBSD and shares internal virus database
with the daemon. <SPAN CLASS="textbf">You must follow some important rules when
using it:</SPAN>
<UL>
<LI>Always stop the daemon cleanly - using the SHUTDOWN command or
the
<BR>
SIGTERM signal. In other case you can lose access
to protected files until the system is restarted.
</LI>
<LI>Never protect the directory your mail-scanner software
uses for attachment unpacking. Access to all infected
files will be automatically blocked and the scanner (including
<code>clamd</code>!) will not be able to detect any viruses. In the
result <SPAN CLASS="textbf">all infected mails may be delivered.</SPAN>
</LI>
</UL>
For example, to protect the whole system add the following lines to
<code>clamd.conf</code>:
<PRE>
ClamukoScanOnAccess
ClamukoIncludePath /
ClamukoExcludePath /proc
ClamukoExcludePath /temporary/dir/of/your/mail/scanning/software
</PRE>
You can also use clamuko to protect files on Samba/Netatalk but a far
more better and safe idea is to use the <SPAN CLASS="textbf">samba-vscan</SPAN> module.
NFS is not supported because Dazuko doesn't intercept NFS access calls.
