 $ centos65stack.sh<br>
 Made for CentOS 6.5. This installs Apache, MySQL, MPM-ITK, Varnish, and PHP. This secures MySQL, creates a user/pass for single domain, creates virtual host entries and folders for one domain. You will be asked for the variables upon running the script.
 
+$ installopenvz-cent6.sh<br>
+Installs OpenVZ and downloads all templates on CentOS 6. Run this, reboot when it asks you to. Done.
+
 $ vzup.sh<br>
 Immature version of an OpenVZ container creation script, thrown together at a moment's notice. Needs some love.
 
 $ centos7lamp.sh<br>
 A very flawed LAMP config for CentOS 7. Apache 2.4 and PHP 5.6. This would be better renamed to "slowly_oom_your_box.sh" if you catch my drift. Apache consumes memory to no end, with no provocation, in this particular recipe.
+
+$ block_user_agents<br>
+This consists of bots that ignore robots.txt and user agents that frequently probed for script vulnerabilities. This is no longer maintained and will not be updated.
+
+$ b2_client_install.sh<br>
+Installs Backblaze B2 client on CentOS 6/7
+
+$ heloblocks<br>
+List of connections blocked by HELO statement on MXroute servers due to excessive spam
