Clamuko
</H2>
Clamuko is a special thread in <I>clamd</I>, that performs on-access
scanning under Linux. It was implemented as a thread in clamd because
of Dazuko implementation. Client (clamuko) - server (clamd) model is
currently not supported by Dazuko. There are some benefits from
current implementation - clamuko is sharing the database with clamd,
and it's updated with the RELOAD command. <B>You must obey the
following principles when using clamuko:</B>
<UL>
<LI>Always stop the daemon cleanly, with QUIT command or
SIGTERM signal. In other case, you can lose an access
to the protected files until the system is restarted.
</LI>
<LI>Never protect the directory your mail-scanner software
uses for attachments unpacking. Access to all infected
files will be blocked, and the scanner (even clamd)
won't be able to detect a virus. Infected mail will be
delivered.
</LI>
</UL>
You need to enable clamuko in <I>clamav.conf</I>. To protect directory
/home, please use the option:
<PRE>
ClamukoIncludePath /home
</PRE>
To protect the whole system:
<PRE>
ClamukoIncludePath /
ClamukoExcludePath /proc
ClamukoExcludePath /tempdir/of/mail/scanner
</PRE>
You can use clamuko to protect file access on Samba/Netatalk. NFS
is not supported (Dazuko doesn't intercept NFS access calls). Another
idea - you can build a database containing a signatures of the popular
exploits, it will protect you against script-kiddies.
