18.5. Tripwire in Interactive Checking Mode

Tripwire must have a database to compare against so we first create the file information database. This action will create a file called tw.db_[hostname] in the directory you specified to hold your databases where [hostname] will be replaced with your machine hostname. To create the file information database for Tripwire, use the command:

[[email protected]] /# cd /var/spool/tripwire/ [[email protected] ]/tripwire# /usr/sbin/tripwire --initialize

We move to the directory we specified to hold our database, and then we create the file information database, which is used for all subsequent Integrity Checking.

Once the file information database of Tripwire has been created, we can now run Tripwire in Interactive Checking Mode. This mode will prompt the user for whether or not each changed entry on the system should be updated to reflect the current state of the file. To run in Interactive Checking Mode, use the command:

[[email protected]] /# cd /var/spool/tripwire/database/ [[email protected] ]/database# cp tw.db_myserverhostname /var/spool/tripwire/ [[email protected] ]/database# cd .. [[email protected] ]/tripwire# /usr/sbin/tripwire --interactive
