Description

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 part of version 4.9.3 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.
