[[email protected] ~]# tripwire-setup-keyfiles ---------------------------------------------- The Tripwire site and local passphrases are used to sign a variety of files, such as the configuration, policy, and database files. Passphrases should be at least 8 characters in length and contain both letters and numbers. See the Tripwire manual for more information. ---------------------------------------------- Creating key files... (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: ## Enter site pass-phrase ## Verify the site keyfile passphrase: ## Re-enter pass-phrase ## Generating key (this may take several minutes)...Key generation complete.

Enter the local keyfile passphrase: ## Enter local pass-phrase ## Verify the local keyfile passphrase: ## Re-enter pass-phrase ## Generating key (this may take several minutes)...Key generation complete. ---------------------------------------------- Signing configuration file... Please enter your site passphrase: ## Enter site pass-phrase ## 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 move this file to a secure location and/or encrypt it in place (using a tool such as GPG, for example) after you have examined it. ---------------------------------------------- Signing policy file... Please enter your site passphrase: ## Enter site pass-phrase ## 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. Once you have a satisfactory Tripwire policy file, you should move the clear-text version to a secure location and/or encrypt it in place (using a tool such as GPG, for example). Now run "tripwire --init" to enter Database Initialization Mode. This reads the policy file, generates a database based on its contents, and then cryptographically signs the resulting database. Options can be entered on the command line to specify which policy, configuration, and key files are used to create the database. The filename for the database can be specified as well. If no options are specified, the default values from the current configuration file are used.

Magento - dbModel read resource does not implement Zend_Db_Adapter_Abstract or Magento install error - Exception printing is disabled
If you enabled full page cache on Zend server this error shows up:
dbModel read resource does not implement Zend_Db_Adapter_Abstract
Trace:#0 C:\xampp\htdocs\magento\app\code\core\Mage\Core\Model\Mysql4\Collection\Abstract.php(68): Varien_Data_Collection_Db->setConnection(false)What you should do next:1. try to clear cache - erase all files from MAGENTO_ROOT/var/cache/ directory2. change settings
1. Navigate to the \"errors\" folder.
2. Change local.xml.sample to local.xml
3. You should now see a new list of crazy errors all over the Magento page - this is okay.
4. Open magento/lib/Zend/Cache/Backend/File.php and look for:
protected $_options = array(\'cache_dir\' => \'null\',
protected $_options = array(\'cache_dir\' => \'tmp/\',
