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 4.20.4-Ubuntu-4.20.4+dfsg-1ubuntu1 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.
