log2pcap

LOG2PCAP(1)							   User Commands						       LOG2PCAP(1)

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 correct for version 3 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.

SEE ALSO

       text2pcap(1), ethereal(1)

AUTHOR

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

       This manpage was written by Jelmer Vernooij.
