7
9 log2pcap [-h] [-q] [logfile] [pcap_file]
10
12 This tool is part of the samba(7) suite.
13
14 log2pcap reads in a samba log file and generates a pcap file (readable
15 by most sniffers, such as ethereal or tcpdump) based on the packet
16 dumps in the log file.
17
18 The log file must have a log level of at least 5 to get the SMB
19 header/parameters right, 10 to get the first 512 data bytes of the
20 packet and 50 to get the whole packet.
21
23 -h
24 If this parameter is specified the output file will be a hex dump,
25 in a format that is readable by the text2pcap utility.
26
27 -q
28 Be quiet. No warning messages about missing or incomplete data will
29 be given.
30
31 logfile
32 Samba log file. log2pcap will try to read the log from stdin if the
33 log file is not specified.
34
35 pcap_file
36 Name of the output file to write the pcap (or hexdump) data to. If
37 this argument is not specified, output data will be written to
38 stdout.
39
40 -?|--help
41 Print a summary of command line options.

67 The original Samba software and related utilities were created by
68 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
69 Source project similar to the way the Linux kernel is developed.
