This is another document I've written on utilizing EnGarde Secure Linux. In this document I show how to configure Tripwire for use with EnGarde Secure Linux 1.0.1. All of the day-to-day report handling can be done through the WebTool, but the initial setup needs to be done manually. 
 Introduction ------------   This document provides the steps a user can perform to configure Tripwire   for use with EnGarde Secure Linux 1.0.1 (Finestra).  It is assumed that the   reader is familiar operating as the root user and knows how to use basic   shell commands.    The proper forum to ask questions is one of the "EnGarde Mailing Lists" (see   "Resources" below).  If you have a problem configuring Tripwire, please send   an email to that list so one of the EnGarde developers can help.   Procedure ---------   Below are the steps you must perform to get Tripwire working.  All of these   steps are required and Tripwire may fail to operate properly should any of   them be skipped.  Please note that once the database has been initialized,   all subsequent functions can be performed through the GD WebTool.     Step 1:  Run the 'twinstall.sh' script   --------------------------------------     This script will walk you through all of the required steps.  ESL ships     with Tripwire 2.3 and a customized policy file.  You should not need to     change the policy file, but if you wish to do so (and are familiar with     the Tripwire policy file format), it can be found at     "/etc/tripwire/twpol.txt".      The first step is to execute the script:        [root@webtool /root]# /etc/tripwire/twinstall.sh      The first thing it will do is prompt you for a "site keyfile passphrase":        (When selecting a passphrase, keep in mind that good passphrases typically       have upper and lower case letters, digits and punctuation marks, and are       at least 8 characters in length.)        Enter the site keyfile passphrase:       Verify the site keyfile passphrase:       Generating key (this may take several minutes)...      You will then be prompted for a "local keyfile passphrase":        Enter the local keyfile passphrase:       Verify the local keyfile passphrase:       Generating key (this may take several minutes)...      Once the key files are set up, the script will then sign your configuration     and policy files.  You will be prompted for your "site passphrase" at each     step of this procedure:        Signing configuration file...       Please enter your site passphrase:       Wrote configuration file: /etc/tripwire/tw.cfg        A clear-text version of the Tripwire configuration file       /etc/tripwire/twcfg.txt       has been preserved for your inspection.  It is recommended       that you delete this file manually after you have examined it.         ----------------------------------------------       Signing policy file...       Please enter your site passphrase:       Wrote policy file: /etc/tripwire/tw.pol        A clear-text version of the Tripwire policy file       /etc/tripwire/twpol.txt       has been preserved for your inspection.  This implements       a minimal policy, intended only to test essential       Tripwire functionality.  You should edit the policy file       to describe your system, and then use twadmin to generate       a new signed copy of the Tripwire policy.     Step 2:  Initalize the Database   -------------------------------     The next step is to initialize the database.  Tripwire will go through all     of the files you have defined in your policy and record information about     their current state.  Later on, when you generate a report, the binaries     will be compared against their recorded values to check their integrity.      To initalize the database, execute the command:        [root@webtool /root]# tripwire --init       Please enter your local passphrase:       Parsing policy file: /etc/tripwire/tw.pol       Generating the database...      You may see some "No such file or directory" messages.  Do not be     alarmed.  If you chose not to enable a service, or if you removed     a package you will see these harmless warnings.      When all is complete, you will see a message such as:        Wrote database file: /var/lib/tripwire/webtool.engardelinux.org.twd       The database was successfully generated.      Tripwire is now successfully configured and installed.     Step 3:  Using the WebTool   --------------------------     Now that Tripwire is set up you can log into the GD WebTool and use the     Tripwire module.  To access the Tripwire module, login and then click on:        Security -> Tripwire Maintenance      Everything here should be rather explanitory.  If you would like more     information on the design of the WebTool Tripwire module and how it     interacts with Tripwire, please refer to the "Tripwire Module Implementation     Details" in the Resources section below.
