NAME
log2pcap - Extract network traces from Samba log files
SYNOPSIS
log2pcap [-h] [-q] [logfile] [pcap_file]
DESCRIPTION
This tool is part of the samba(7) suite.
log2pcap 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.
The log file must have a log level of at least 5 to get the SMB
header/parameters right, 10 to get the first 512 data bytes of the
packet and 50 to get the whole packet.
OPTIONS
-h
If this parameter is specified the output file will be a hex dump,
in a format that is readable by the text2pcap utility.
-q
Be quiet. No warning messages about missing or incomplete data will
be given.
logfile
Samba log file. log2pcap will try to read the log from stdin if the
log file is not specified.
pcap_file
Name of the output file to write the pcap (or hexdump) data to. If
this argument is not specified, output data will be written to
stdout.
-?|--help
Print a summary of command line options.
EXAMPLES
Extract all network traffic from all samba log files:
$ log2pcap < /var/log/* > trace.pcap
Convert to pcap using text2pcap:
$ log2pcap -h samba.log | text2pcap -T 139,139 - trace.pcap
VERSION
This man page is part of version 4.16.11 of the Samba suite.
BUGS
Only SMB data is extracted from the samba logs, no LDAP, NetBIOS lookup
or other data.
The generated TCP and IP headers don't contain a valid checksum.
Source project similar to the way the Linux kernel is developed.
