Apache 2.2 and Active Directory and Group restrictions
Posted by Michael on July 22, 2009 in Configuration, Servers, Setups, Systems
I was really struggling with getting Apache and Active Directory talking and restricting access (authorizing) only a sub-set of users that belonged to a particular group. Here, I show you how I solved the problem.
The Stage
I am setting up a Ubuntu server with Apache 2.2 and authenticating users against a Windows 2003 Server’s Active [...]
macports is not darwinports
Posted by Michael on June 23, 2009 in Macs, Setups, Systems
For those of you who don’t keep a close eye on the macports system that provides you with convenient builds of popular open source software, let me put you on guard: macports supplanted darwinports a few years back to avoid continued confusion over the name.
I was having a good bit of trouble getting ports [...]
Rails vs. Ramaze Performance Comparison
Posted by Michael on February 19, 2009 in General, SQL, Servers, Systems
One of my biggest concerns of late is that my “more than just a little trivial” Rails projects seem to find their way straight into the heavyweight category in no time at all. While I am quite hopeful that Merb being the 3.0 version of Rails will resolve many of the issues I face [...]
Ruby, Mysql, CentOS 5, and 64-bit
Posted by Michael on January 19, 2009 in SQL, Systems
I have lately switched away from Ubuntu as my desktop and started using CentOS 5.2 because I wanted better support for a lot of RAM and virtualization (where I can quickly commission Linux servers to build out my testbed of target environments). With the change, I also make the leap into pure 64-bit libraries with [...]
Overview of Xen Virtualization
Posted by Michael on November 24, 2008 in Servers, Systems
Many people start looking at Virtualization Technologies because of the promise of doing more with less and high-availability solutions that the technology offers. However, there are many other benefits to virtualizing your data center, which are explored herein. Here, we will mainly focus on the free, open-source offering of Xen. This post [...]
Getting mouse wheel to work with KVM and Ubuntu
Posted by Michael on November 3, 2008 in Servers, Systems
I have been busy getting a Ubuntu based Network Attached Storage server up and running as well as finally switching my trusty desktop to Ubuntu running my old Windows XP as a VMWare Server image. All was fine and dandy until I decided to add a KVM to the mix so I could easily switch [...]
Jumpstarting your Virtual tour with Oracle VM
Posted by Michael on October 29, 2008 in Servers, Systems
Server virtualization technology has come a long ways in the last 18 months (today being a wonderful October 28, 2008 crisp, cold Fall Sunny day). Here, I am going to take a look at Oracle VM, one of the relative newcomers to the game and show you how to quickly get up and running with [...]
Converting Oddmuse Wiki to Edgewall Trac
Posted by Michael on October 2, 2008 in Macs, Programming, Python Language, Ruby Language, SQL
Our company began long ago with wiki’s, but we chose the Oddmuse wiki way back when. These days, we’re heavy users of Trac wiki because of its integrated ticket support system. So what to do with all those old wiki’s that folks have stopped using and reading. The Oddmuse wikis still hold [...]
Changing ANSI colors in Terminal on Macs
Posted by Michael on September 9, 2008 in General, Servers, Systems
Probably the most frustrating experience I have had with Macs so far is figuring out how to change the ANSI colors in Terminal (Terminal.app) so that I can read the outputs of man and most especially ls and comments in vi when colorization is activated and I have chosen a dark background theme.
I am using [...]
Configuring ntpd to hand out time to local servers
Posted by Michael on August 11, 2008 in General, Servers, Systems
Syncing your servers to public time servers is one of the most common ways of keeping server times in sync. Apparently the less common approach of configuring one server to sync with public servers and it in turn becomes the authoritative time keeper for the rest of your servers is less well-known. Digging [...]
