.SH NAME
log2pcap \- Extract network traces from Samba log files
.SH "SYNOPSIS"
.nf
\fBlog2pcap\fR [-h] [-q] [logfile] [pcap_file]
.fi
.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
$ cat /var/log/* | log2pcap > 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\&.
.PP
This manpage was written by Jelmer Vernooij\&.
