Clam daemon
</H2>
<code>clamd</code> is a multi-threaded daemon that uses <I>libclamav</I>
to scan files for viruses. It may work in one or both modes listening on:
<UL>
<LI>Unix (local) socket
</LI>
<LI>TCP socket
</LI>
</UL>
The daemon is fully configurable via the <code>clamd.conf</code> file
<A NAME="tex2html13"
HREF="footnode.html#foot210"><SUP>5</SUP></A>. <code>clamd</code> recognizes the following commands:
<UL>
<LI><B>PING</B>
<BR>
Check the daemon's state (should reply with "PONG").
</LI>
<LI><B>VERSION</B>
<BR>
Print program and database versions.
</LI>
<LI><B>RELOAD</B>
<BR>
Reload the databases.
</LI>
<LI><B>SHUTDOWN</B>
<BR>
Perform a clean exit.
</LI>
<LI><B>SCAN file/directory</B>
<BR>
Scan file or directory (recursively) with archive support
enabled (a full path is required).
</LI>
<LI><B>RAWSCAN file/directory</B>
<BR>
Scan file or directory (recursively) with archive and special file
support disabled (a full path is required).
</LI>
<LI><B>CONTSCAN file/directory</B>
<BR>
Scan file or directory (recursively) with archive support
enabled and don't stop the scanning when a virus is found.
</LI>
<LI><B>MULTISCAN file/directory</B>
<BR>
Scan file in a standard way or scan directory (recursively) using
multiple threads (to make the scanning faster on SMP machines).
</LI>
<LI><B>STREAM</B>
<BR>
Scan stream: <code>clamd</code> will return a new port number you should
connect to and send data to scan.
</LI>
<LI><B>SESSION, END</B>
<BR>
Start/end a <code>clamd</code> session - you can do multiple commands
per TCP session (WARNING: due to the <code>clamd</code> implementation the
<B>RELOAD</B> command will break the session).
</LI>
</UL>
and reacts on the special signals:
<UL>
<LI><B>SIGTERM</B> - perform a clean exit
</LI>
<LI><B>SIGHUP</B> - reopen the log file
</LI>
<LI><B>SIGUSR2</B> - reload the database
</LI>
</UL>
