LOG2PCAP(1) User Commands LOG2PCAP(1)NAMElog2pcap - Extract network traces from Samba log files
SYNOPSISlog2pcap [-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 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.

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.

NOTES
Source code for Samba is available in the SUNWsmbaS package.
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.
