Opscode, Turning Sysadmins into Superheroes

For the last few years I have had an interest in configuration management of IT infrastructure. While by no means an expert I have a considerable amount of experience with the problems associated with mass server configuration and have come to believe it also one of the most under-served disciplines in systems management.

In a previous life I had an operations role maintaining primarily Linux servers and other open source infrastructure. In 2006 I worked on launching the open source NetDirector project, a graphical tool for configuring open source infrastructure like Apache, Samba, LDAP and NFS servers. During that time the challenges of …

Cloud Lock-in

I wrote this post for the Zenoss community blog today, on cloud lock-in today. Rather than cross-posting I’ll just give you the lead in and you can read it there if you like.

Cloud Computing and Virtualization Resources

I have been a little bit stubborn on my concession that cloud computing is really going to be the wave of the future. Though lately I have been playing with a lot of cloud related technologies and am hooked. Spin up 10 (or 100) Linux servers in a minute from a web page with no real systems management skills and then you start seeing the power of cloud computing. As I try to get smarter on cloud computing I compiled the following list of resources that I have found helpful.  If you have a great cloud resource please feel free to let me know what I am missing on.

Eleven Open Source Cloud Computing Projects to Watch

Last month cloud computing and systems management expert John Willis published his best of Cloud Computing for 2009 list he calls the Cloudies.  I am not an expert on the latest developments in cloud computing so it was nice to get a list of the best (in his expert opinion) cloud computing tools. I was especially interested in the latest open source software and I did a little research on each of these projects to see if they had active development mailing lists, regular releases  and a real community behind …

Securing Wordpress

A couple of  weeks ago I got an unhappy email from my web hosting provider telling me I was in violation of their Terms of Service. Of course I called them immediately and was told that there was a “phishing page” hidden in one of my web directories. My blog had been hacked, so I immediately started doing some house cleaning.

After the initial once over and deletion of any suspicious files I went looking for advice on how to “harden my installation”. Here’s what I found:
