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.
