NAME
fw1_lea2dlf - convert Check Point FireWall-1 NG logs to firewall DLF
SYNOPSIS
fw1_lea2dlf file
DESCRIPTION
fw1_lea2dlf converts Check Point FireWall-1 NG logs into firewall DLF format. Input for
this converter is the output of fw1-loggrabber, a simple LEA (Log Export Api) client.
ACTIVATION INSTRUCTIONS
This DLF converter isn't activated by default in Lire. It requires the Date::Manip perl
module and the fw1-loggrabber tool. Date::Manip can be installed from CPAN. fw1-loggrabber
is available from http://sourceforge.net/projects/fw1-loggrabber .
If both of these components are installed, you can activate the fw1_lea DLF conveter by
uncommenting its line in the file @sysconfdir@/@PACKAGE@/address.cf
OTHER NOTES
Beware! In case you're getting a lot of warnings complaining about UTF-8 characters,
looking like:
all all UNSET fw1_lea2dlf warning Malformed UTF-8 character
(unexpected non-continuation byte 0x7a, immediately after
start byte 0xe3) at /usr/lib/perl5/vendor_perl/5.8.0/Date/Manip.pm
line 5931.
, and your locale is UTF-8 enabled, there is a workaround: Set the LANG and LC_CTYPE
environment variables to en_US instead of e.g. en_US.UTF-8. You can do this temporarily
within the call of the converter:
LANG=en_US LC_CTYPE=en_US ./fw12dlf < /your/log/file
fw1-loggrabber
fw1-loggrabber is build using OPSEC's Software Development Kit. OPSEC (Open Platform for
Security, http://www.opsec.com/) is an open, multi-vendor security framework.

********************************************************
1) Prerequisites
a) for running FW1-LOGGRABBER
FW1-LOGGRABBER is statically linked and can therefore be
run on the following systems:
* Linux (Tested distributions are Red Hat, SuSE and De-
bian with Kernel Versions 2.2.x and 2.4.x)
* Solaris SPARC (Tested versions are Solaris 8 and 9)
* Windows NT/2000/XP (currently no W32 of FW1-LOGGRABBER
is available yet and therefore not yet tested)
b) for building FW1-LOGGRABBER
FW1-LOGGRABBER uses API-functions from Checkpoints'
OPSEC SDK. In order to be able to build applications
which are using this SDK, a very special build environ-
ment has to be used. Currently building FW1-LOGGRABBER is
supported only for Solaris SPARC platform and the Linux
platform.
* Linux
- Red Hat 6.2
- gcc 2.95.1
- Checkpoint OPSEC SDK NG-FP3 for Linux 2.2
* Solaris SPARC
- Solaris 8
- gcc 2.95.2
- Checkpoint OPSEC SDK NG-FP3 for Solaris SPARC
* Windows
- EDITME
3) How to Use
a) Configure FW1 to enable LEA-Protocol
In order to be able to use this tool with a Checkpoint
FW-1 installation, the following tasks have to be done:
* modify $FWDIR/conf/fwopsec.conf and define the port
for unauthenticated lea connections.
# lea_server auth_port 18184
lea_server port 50001
* bounce FW1 (cpstop / cpstart) to activate changes
* add rule to policy to enable connections on port
50001 to the FW-1 Management-Server
b) Usage of FW1-LOGGRABBER
FW1-LOGGRABBER is statically linked and therefore not
dependent of OPSEC libraries. The binary can be run on
any Linux or Solaris SPARC system.
Command-Line Options:
-s IP-Address of FW1-Management-Server
-p unauthenticated LEA-Port of FW1-Server
-f exact name of FW1-Logfile or pattern to
be matched on FW1-Logfiles.
--resolve Resolve IP-Addresses to Names
--noresolve Do not resolve IP-Addresses to Names
--showfiles Only show available FW1-Logfiles and exit.
--debug Enable debug-mode of FW1-LOGGRABBER
Examples:
o fw1-loggrabber -s 192.168.2.254 -p 50001 --showfiles
Show all logfiles that are available on the FW1-Manage-
ment-Server with the IP-Address 192.168.2.254. The LEA-
Port the Management-Server is listening for unauthenti-
cated connections is 50001.
o fw1-loggrabber -s 192.168.2.254 -p 50001
Show all logentries of the default FW1-Logfile (fw.log)
on the FW1-Management-Server with the IP-Address
192.168.2.254 and the LEA-Port 50001.
o fw1-loggrabber -s 192.168.2.254 -p 50001 -f 2003-03-27_213652.log
Show all logentries of the specified logfile. If the Log-
file doesn't exist on the specified FW1-Management-Server,
no entries are returned.
o fw1-loggrabber -s 192.168.2.254 -p 50001 -f 2003-03
Show all logentries of all logfiles on the FW1-Management-
Server, that contain the pattern "2003-03", i.e. all Log-
Files from March 2003
o fw1-loggrabber -s 192.168.2.254 -p 50001 -f fw.adtlog
Show all logentries of audit logfile on FW1-Management-Server
4) Change History
* 1.0 - Initial Version (2003/03/30)
o get all available FW1-Logfiles
o get data of one or more FW1-Logfiles
5) Features to be implemented
* Implementation of authenticated connections
* Win32 build
EXAMPLES
To process a log as produced by FW-1:
$ fw1-loggrabber -s 192.168.2.254 -p 50001 -f fw.log | fw12dlf
fw1_lea2dlf will be rarely used on its own, but is more likely called by lr_log2report:
$ fw1-loggrabber -s 192.168.2.254 -p 50001 -f fw.log | \
lr_log2report fw1_lea
BUGS / TO DO
This convertor needs perl's Date::Manip library. It'd better use another module for this,
used by more Lire code.
The status and licensing of fw1-loggrabber is unknown.
