33 <manvolnum>7</manvolnum></citerefentry> suite.</para>
35 <para><command>log2pcap</command> reads in a
36 samba log file and generates a pcap file (readable
37 by most sniffers, such as ethereal or tcpdump) based on the packet
38 dumps in the log file.</para>
40 <para>The log file must have a <parameter>log level</parameter>
41 of at least <constant>5</constant> to get the SMB header/parameters
42 right, <constant>10</constant> to get the first 512 data bytes of the
43 packet and <constant>50</constant> to get the whole packet.
48 <title>OPTIONS</title>
53 <listitem><para>If this parameter is
