3.1. 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

A Tripwire tab on your cluster's home page will indicate that tripwire is installed.

When the tripwire cron job runs, clicking on the tab will result will bring up the most recent tripwire report and a set of monthly archives of previous reports

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.

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

3.1.1. Changing the Target Email Address

To have tripwire email its report to a different email address. Simply run the rocks set tripwire mail address1 [address2]. For example, say you want to email the tripwire reports to go to [email protected] and root.

rocks set tripwire mail [email protected] root@`hostname`

To view the set of addresses for the Tripwire Daily Report

rocks list tripwire mail
