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. <P> <BR><HR> <ADDRESS> Tomasz Kojm 2009-10-28 </ADDRESS> </BODY> </HTML>
