NAME

       Lire::Firewall::IpfilterDlfConverter - convert ipf (ipmon) logs to firewall DLF

DESCRIPTION

       Lire::Firewall::IpfilterDlfConverter converts Ipfilter logs into firewall DLF format.  Input for this converter is the standard ipf syslog
       log file as produced by ipmon. IP Filter is shipped with FreeBSD, OpenBSD (up to 2.9) and some other OS's.

EXAMPLE

       A ipfilter logfile which looks like

NAME

       Lire::WELF - Base implementation of a WebTrends(tm) Enhanced Log Format parser

SYNOPSIS

       use Lire::WELF;

       my $parser = new Lire::WELF;

       my $welf_rec = $parser->parse( $line );

DESCRIPTION

       This module defines an object able to parse WebTrends(tm) Enhanced Log Format. That log format was defined by WebTrends(tm) for its
       Firewall Suite. It defines an extensible format that is now used by several packet filter and/or proxy firewall.

       The document describing that format is available from http://www.webtrends.com/partners/welfOverview.htm

       A list of products/vendor that supports this format can be found at http://www.webtrends.com/partners/firewall.htm

       You create a WELF parser object using the new() method:

	   my $parser = new Lire::WELF();

       To parse a WELF record you invoke the parser() method with the line containing the record as parameter:

	   my $rec    = $parser->parse( $line );

       The $rec is an hash reference with the WELF field name used as keys and the value of the records as values.

       No value are interpreted or checked in any except for the following:

       time
	   The time field will be converted to epoch time

       quotation
	   The quotation marks used when the value contains spaces are removed.

   WELF EXTENSIONS
       The parser also supports "extensions" to the format found in the field.

       port
	   We will interpret correctly src and dst fields that have the port embededded in them:

	       src=192.168.1.1:1037

       interface
	   A possible :IFNAME will also be interpreted as the interface name:

	       dst=192.168.100.10:23:WAN

       timezone
	   The time field may contains a time zone identifier:

	       time="2001-12-02 12:34:12 UTC"

   Derived Fields
       The parser will generate a few 'derived' to complete the format.

       src_port
	   Will contain the src port portion of the dst field when SonicWall extensions are used.

       dst_port
	   Will contain the interface portion of the dst field when SonicWall extensions are used.

       src_if
	   Will contain the interface portion of the src field when SonicWall extensions are used.

       dst_if
	   Will contain the interface portion of the dst field when SonicWall extensions are used.
