In other case you can lose an access to protected files until the system is restarted. </LI> <LI>Never protect a directory your mail-scanner software uses for attachment unpacking. Access to all infected files will be automatically blocked and the scanner (even <code>clamd</code>) won't be able to detect any virus. In the result <B>all infected mails will be delivered.</B> </LI> </UL> For example, to protect a 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 far more better and safe idea is to use the <B>samba-vscan</B> module (see <A HREF="node61.html#samba-vscan">8.14</A>). NFS is not supported because Dazuko doesn't intercept NFS access calls. <P> <BR><HR> <ADDRESS> Tomasz Kojm 2004-10-17 </ADDRESS> </BODY> </HTML>
