.SH "DESCRIPTION"

.PP
This tool is part of the \fBsamba\fR(7) suite\&.

.PP
\fBlog2pcap\fR 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\&.

.PP
The log file must have a \fIlog level\fR of at least \fB5\fR to get the SMB header/parameters right, \fB10\fR to get the first 512 data bytes of the packet and \fB50\fR to get the whole packet\&.

.SH "OPTIONS"

.TP
\-h
If this parameter is specified the output file will be a hex dump, in a format that is readable by the text2pcap utility\&.

.TP
\-q
Be quiet\&. No warning messages about missing or incomplete data will be given\&.

.TP
logfile
Samba log file\&. log2pcap will try to read the log from stdin if the log file is not specified\&.

.TP
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\&.

.TP
\-h|\-\-help
Print a summary of command line options\&.

.SH "EXAMPLES"

.PP
Extract all network traffic from all samba log files:

.PP

.nf

			$ log2pcap < /var/log/* > trace\&.pcap
	.fi


.PP
Convert to pcap using text2pcap:

.PP

.nf

	$ log2pcap \-h samba\&.log | text2pcap \-T 139,139 \- trace\&.pcap
	.fi


.SH "VERSION"

.PP
This man page is correct for version 3\&.0 of the Samba suite\&.

.SH "BUGS"

.PP
Only SMB data is extracted from the samba logs, no LDAP, NetBIOS lookup or other data\&.

.PP
The generated TCP and IP headers don't contain a valid checksum\&.

.SH "SEE ALSO"

.PP
\fBtext2pcap\fR(1), \fBethereal\fR(1)

.SH "AUTHOR"

.PP
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\&.
