On-access Scanning

There is a special thread in <code>clamd</code> that performs on-access
|
|
|
|
|
scanning under Linux 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>
|
|
|
|
|
ScanOnAccess yes
|
|
|
|
|
OnAccessIncludePath /
|
|
|
|
|
OnAccessExcludePath /proc
|
|
|
|
|
OnAccessExcludePath /temporary/dir/of/your/mail/scanning/software
|
|
|
|
|
</PRE>
|
|
|
|
|
For more configuration options, type 'man clamd.conf' or reference the
|
|
|
|
|
example clamd.conf.
