Build Your Own Home Router
Today we’re going to build a router. Yes, that’s right, we’re venturing into networking, which for many is uncharted, technically daunting territory. Together we will work through all of the steps required to build a high performance, Linux-based router I have named alpha — almost totally from scratch. What’s more, when it comes to speed, reliability, security, and customization, the router we build will […]
Flashing the IPMI firmware on a Supermicro X9DRW-iF
I recently tasked myself with bringing IPMI up to date on a Supermicro X9DRW-iF server. This can be quite dangerous, asÂ a bad IPMI flash can break IPMI in a way that requires you end up having to mail your hardware (RMA) to Supermicro to get it re-flashed. As such, I’m not hugely fond of doing these sorts of things through a web interface, as it depends on the network, and the Supermicro web interface doesn’t give you much in the way of feedback during the firmware upgrade process.Â Today, I’ll be sharingÂ what I found to beÂ the most stableÂ way of flashing the IPMI firmware on an X9DRW-iF. We’ll be doing so from an OS that is installed on the hardware itself — in our case from CentOS 6.6 (this would very likely work just fine on a Debian-based OS as well).

Install Ruby on Rails on Ubuntu 10.10
In my post, Install CakePHP on Ubuntu 10.10 and 11.10, we took an in-depth view into installing CakePHP on Ubuntu 10.10. Since then, I’ve received some emails that collectively critiqued my choice of foundational programming language and suggested Ruby on Rails would be more well-received. PHP has historically been a bit of a security nightmare, […]
Install CakePHP on Ubuntu 10.10 and 11.10
CakePHP is a framework that allows for rapid PHP development. I recently installed it on one of my home test servers and there were a few steps specific to an Ubuntu install that were required but that were not clearly outlined in the official documentation. The version of the Apache web server that gets installed […]
