How-To: Purge old Ubuntu kernels
How do you keep your /boot clean of old kernels in Ubuntu (or any other Debian derivative)? This script can do it for you.
How do our servers connect?
This morning we had an outage and while I did what I could to describe it via text, I can’t seem to come to grips with three unrelated issues occurring together creating so many pages. Why? Our network is segmented/separated by multiple physical segments and these unrelated incidents should not affect the other. This graphic representation isn’t necessarily 100% accurate […]
The dilemma – OS updates vs OS type
For years I have been a FreeBSD bigot. I love FreeBSD, the stability, performance, ease of use, and steady progression. But… Updates are kind of a chore, there is no such thing as true incremental updates, you either do patch updates against RELEASE, or you do world updates against STABLE. I am a STABLE kind of admin so my updates […]
Linux Distributions vs PHP
The splintering of Linux distributions seems to be continuing! This week, I have had requests for PHP versions 5.3 and 5.2 on both Red Hat EL 5 and CentOS 5 – though never distribution supports higher than 5.1.6 in the official repositories. PHP 5.2 has been out quite a while. Ubuntu Hardy LTS has it and it is 2 years […]
Example cost: Virtual Private Cloud (updated)
Back in September, 2009, I had written a post with a quick overview of what a private cloud (or infrastructure) looks like and some basic costs and information, including why it is a great product (I am biased). Since then, Dell has retired the PE2900III model server and items change, this is an update for the basic configuration. Reminder graphic: […]
Shell service available
Been a long week and I had to deal with some red tape internally (of my own creation!), but finally have some working shell service to sell to people who want it. I had posted last week about the issue(s) of shell services and decided that I would do the work to put this kind of service together as I […]
Example cost: Virtual Private Cloud on VMware
In the last 6 months, I have helped multiple customers achieve their dream of a virtual machine environment built for them exclusively, but with abilities to control their virtual machine setup, configuration, turn up, tear down, etc. These dedicated infrastructure environments are in the ipHouse data center. This isn’t ‘cloud computing’ as many people think of it (thanks to Amazon […]
Linux Sucks! – a presentation
“Linux Sucks!” from Brian Lunduke was a great presentation showing why Linux can’t hit mainstream at this point in time. He does this without creating offense or alienating his audience.
ipHouse releases VMware based server services
Virtualization, one of the buzzwords flying around the Internet today, is a method of running separate servers (guests) with separate operating systems on shared physical hardware (the host). I wrote a quick summary back in February, 2009 that should help give some context. Here at ipHouse, we have chosen to use VMware for our virtualization products. We chose VMware because […]
