Troubleshooting Tools

This chapter describes the most important tools for Troubleshooting VPN-1/FireWall-1 problems. These tools

include fwinfo, Control (fw ctl) commands, the Monitor (fw monitor) Command and debugging with

INSPECT.

fwinfo

Introduction

fwinfo is used to collect information that is used for debugging and solving VPN-1/FireWall-1 problems. It

runs operating system and VPN-1/FireWall-1 commands and gathers information on the system parameters of

the machine on which VPN-1/FireWall-1 is installed, and on VPN-1/FireWall-1 parameters such as interfaces

and tables. The resulting file will usually be sent to Check Point Support (su[email protected]eckpoint.com)for

analysis.

How to create fwinfo

On NT

Issue the command:

fwinfo > file_name

The resulting file file_name will be uncompressed and not decoded. You should compress it before sending

it to Check Point Support for analysis. Use any zip utility such as gzip, pkzip or winzip.

On UNIX

1. Before running fwinfo, make sure that the result of the echo $FWDIR command is /etc/fw

(normally the FireWall directory). If it isn’t, type

setenv FWDIR /etc/fw

2. Login as a super user (recommended)

3. Run the script

$FWDIR/bin/fwinfo | compress | uuencode fwinfo.Z > /tmp/fwinfo.uue

which will do the following:

(1) Run the fwinfo script (the directory will be tar compressed to fwinfo.tar,then

(2) gzip the file to fw.tar.gz,then

(3) uuencode it to fwinfo, then

(4) Compress it under the original file name fwinfo.Z,then

(5) The file will be uuencoded

The result is the file /temp/fwinfo.uue
