	<title>DESCRIPTION</title>

	<para>This tool is part of the <citerefentry><refentrytitle>Samba</refentrytitle>
	<manvolnum>7</manvolnum></citerefentry> suite.</para>

	<para><command>log2pcap</command> reads in a 
	samba log file and generates a pcap file (readable 
	by most sniffers, such as ethereal or tcpdump) based on the packet 
	dumps in the log file.</para>

	<para>The log file must have a <parameter>log level</parameter> 
	of at least <constant>5</constant> to get the SMB header/parameters 
	right, <constant>10</constant> to get the first 512 data bytes of the 
	packet and <constant>50</constant> to get the whole packet.
	</para>
