3.1. Using Tripwire

Tripwire is configured to automatically scan the files on your frontend daily. This is accomplished via cron. To test the tripwire cron script, execute:

# /etc/cron.daily/tripwire

When this cron script runs successfully, tripwire sends mail to root (default). The cron script also creates a web page which shows the most recent tripwire report and web-archives of previous reports. See http://localhost/tripwire

To view the mail message, execute mail, then hit return at the & prompt. You'll see a mail message that looks similar to:

[root@rocks22 root]# mail
Mail version 8.1 6/6/93.  Type ? for help.
"/var/spool/mail/root": 1 message 1 new

3.1.1. Changing the Target Email Address

To have tripwire email its report to a different email address. Simply run the /opt/tripwire/etc/tw-email-to -set address1 [address2]. For example, say you want to email the tripwire reports to go to wopr@wargames.org and root.

/opt/tripwire/etc/tw-email-to -set wopr@wargames.org root@`hostname`

To view the set of addresses for the Tripwire Daily Report

/opt/tripwire/etc/tw-email-to
