NAME

       pix2dlf - convert PIX logs to the firewall DLF format

SYNOPSIS

       pix2dlf

DESCRIPTION

       This script expects syslog-type logs from a Cisco PIX firewall on stdin.  Messages with severity level informational (6) and up should be
       logged.	These look like e.g.:

	Jan 15 12:58:37 pix1 %PIX-4-106543: Deny tcp src outside:1.2.3.4/1234 dst
	 inside:2.3.4.5/80 by access-group "foo"
	Jan 16 10:37:09 pix1 %PIX-4-106543: Deny udp src outside:3.4.5.6/137 dst
	 inside:4.5.6.7/137 by access-group "foo"
	Jan 17 08:43:46 pix1 %PIX-4-106543: Deny icmp src outside:5.6.7.8 dst
	 inside:6.7.8.9 (type 8, code 0) by access-group "foo"
	Jan 24 00:07:39 pix1 %PIX-6-302000: Teardown TCP connection 178359 faddr
	 7.8.9.10/102 gaddr 8.9.10.11/21652 laddr 9.10.11.12/4107 duration
	 0:00:01 bytes 755 (TCP FINs)
	Jan 24 00:07:45 pix1 %PIX-6-302000: Teardown UDP connection for faddr
	 10.11.12.13/711 gaddr 11.12.13.14/1259 laddr 12.13.14.15/1259

       That is

	syslog_time_stamp log_host %PIX-Level-Message_number: Message_text

       See also http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_62/ syslog/pixemint.htm#xtocid11 .

       It will output DLF records in the Lire firewall DLF format on STDOUT.

       For now, only messages

	%PIX-2-106001
	%PIX-2-106002
	%PIX-2-106006
	%PIX-2-106007
	%PIX-3-106010
	%PIX-3-106014
	%PIX-6-106015
	%PIX-1-106021
	%PIX-4-106023
	%PIX-6-302002
	%PIX-6-302006
	%PIX-6-302014
	%PIX-6-302016

       are used.  Note that severity level 1 is `alert', 6 is ` informational'. (0 is `emergency', 7 is `debugging'.)

EXAMPLES

       To process a log as produced by a Cisco PIX:

	$ pix2dlf < pix.log

       pix2dlf will be rarely used on its own, but is more likely called by lr_log2report:

	$ lr_log2report pix < /var/log/pix.log

BUGS

       This script hasn't yet been tested by a very wide range of log files, and therefore is not mature yet.

       Studying the Cisco documentation for any changes in the log file format, e.g.  between PIX Firewall Version 4.0 and 6.2, has not been done
       yet.

       We probably do not support any of the PIX products really fully.  We've found documentation for log files for PIX version 4.3, 4.4, 5.0,
       5.1, 5.2, 5.3, 6.0, 6.1 and 6.2, but didn't implement all peculiarities found in these docs yet.  This script strives to support PIX 6.2 in
       most common cases.

       When hacking on this script, beware that log syntax has changed during PIX development.	Furthermore, note that some rudimentary state is
       represented in PIX logs.  This state is not used yet in this script.
