Block All Traffic to Your New Remote Server

I block all traffic to a new server while I setup users and environment using Netfilter AKA iptables. Nothing else gets in or out of the box but me. This requires 2 scripts actually. One to close the machine to all other IPs but mine, and one to “unblock”. You need to unblock while installing other software, re. LAMP, when...

Fix Magento Missing Images In Checkout Cart

When moving a magento instance to a new server, it seems the product cache exhibits some very strange behavior making a fix to the new server almost impossible after the fact. That means the problem is an imprecise backup and transfer process. The problem seems to be a result of a mismatch between the database and some files (cache).

9 Steps To Setup SSL on UBUNTU 12.04 APACHE 2.22

I found a lot of misleading and confusing How-To stuff when installing an SSL certificate on Ubuntu 12.04 LTS and Apache 2.22. I also share most people confusion when it comes to encryption. Only after a lot of repetition has the fog begun to clear. It helps to realize: The “key” is your PRIVATE file. Don’t ever share it. Its stays...

How To Manage Fail2ban Using Perl Script On Remote Servers and A Control Mysql Database

Earlier I posted how to use a text file created by a script to similarly manage the rogue IPs that Fail2ban bans. The problem with using scripts and crontab is that it is not reporting in real-time. The method here works in real-time because Fail2ban reports directly to the MySQL on the control server. On each remote you’ll want to...
