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.
-h|--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 3.0 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.

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.

Samba(7) delivers the set of four SMF(5) services as can be seen from the following example:
$ svcs samba wins winbind swat
STATE STIME FMRI
disabled Apr_21 svc:/network/samba:default
disabled Apr_21 svc:/network/winbind:default
disabled Apr_21 svc:/network/wins:default
disabled Apr_21 svc:/network/swat:default
where the services are:
"samba"
runs the smbd daemon managing the CIFS sessions
"wins"
runs the nmbd daemon enabling the browsing (WINS)
"winbind"
runs the winbindd daemon making the domain idmap
"swat"
Samba Web Administration Tool is a service providing access to browser-based Samba administration interface and on-line documentation.
The service runs on software loopback network interface on port 901/tcp, i.e. opening "http://localhost:901/" in browser will access
the SWAT service on local machine.
Please note: SWAT uses HTTP Basic Authentication scheme where user name and passwords are sent over the network in clear text. In the SWAT
case the user name is root. Transferring such sensitive data is advisable only on the software loopback network interface or over secure
networks.
