  • Ridiculously simple NTLM Authentication for Apache (Ubuntu) | Kieran Barnes-Lucas
    We all know Ubuntu makes things amazingly simple. This is the best I’ve found so far. NTLM authentication in Apache used to take a while to setup, it used to be tricky, fiddly – generally a bit hit and miss.

  • IOWait. (Sysadmin’s bedtime horror story) – […] hope this helps someone out there. The last 3 days, I have had my server crash on me every 2-3 hours. At first I thought it would be a spike in the traffic, since I couldn’t find any crash reports from Apache, and there was a spike in the traffic at this time. So I increased the resources on the server. It crashed again, every 2-3 hours […] It wasn't my case but… who knows in the future?
  • Apache mod_deflate and mod_cache issues | Devon Hillard’s Digital Sanctuary – The Problem: Using Apache mod_deflate and mod_disk_cache (or other mod_cache) together can create far too many cached files. The Background: Apache is a web server with many different modules you can load in to enhance it. Two common ones are mod_deflate and mod_cache (or mod_disk_cache).

  • My Blog: AWS EC2 Auto Scaling: Basic Configuration – Our goal: Create an Auto Scaling EC2 Group in a single Availability Zone and use a HTTP status page as a Health Monitor for our Load Balancer and the Auto Scaling group instances. This exercise will show us some Auto Scaling basics and will be useful to understand the concepts beneath but the Auto Scaling Group will not automatically "scale" responding to external influence like Average CPU Usage or Total Apache Connections (This aspect is covered in this post: AWS EC2 Auto Scaling: External CloudWatch Metric). With the Auto Scaling configuration described here, we will obtain a web server cluster that can be increased and decreased in members with a simple Auto Scaling API call and we will transfer the monitoring role to the ELB to automatically replace failed EC2 instances or web servers.
  • Autoscaling with custom metrics « That’s Geeky – One of the appeals of cloud computing is the idea of using what you need when you need. One of the ways that Amazon provides for this is through autoscaling. In essence, this allows you to vary the number of (related) running instances according to some metric that is being tracked. In this article, we look at how you can trigger a change in the number of running instances using a custom Cloudwatch metric – including the setup of said metric, and a brief look at the interactions between the various autoscaling commands used.
  • Painless AWS Auto Scaling With EBS Snapshots And Capistrano – Boom – AWS (Amazon Web Services) auto scaling is a simple concept on the surface: You get an AMI, set up rules, and the load balancer takes care of the rest. However, actually getting it done is more complicated. Some choices are worse than others: you could bake an AMI (Amazon Machine Image) before you deploy, but that could add 10 minutes or more to each deployment. Some are dangerous: you could create an AMI after each deploy, but you run the risk that an auto scale even happens before your AMIs are done. Plus, you have a whole variety of AMIs deployed in at any given time. Some are similar to what we propose in this tutorial: you could push your code to S3 on each deploy and have user-data scripts that pull it down on each auto scaling event. However you slice it, to get auto scaling to fit into your development work flow in a transparent way takes careful thought and planning. We recently rolled out the following solution at CodePen. It keeps our AMIs static and our application ready for scaling on EBS (Elastic Block Store) snapshots. We can push code using Capistrano and let a few scripts distribute the ever-changing code base to our fleet of servers. I’d like to share the steps required to make it work. This series of posts will walk you through the steps required to build an auto-scaling infrastructure that stays out of your way.
  • : establishing geek cred since 1305712800 – Did you accidentally set node.normal[:foo][:bar] = 'something bad' in your chef recipe? Then you found that the node's normal attributes persisted between chef runs, and you really wanted to use the default attribute precedence level in your cookbook's attributes/default.rb file?

  • PassCore: A Self-Service AD Password Change Utility – Home – PassCore is a very simple 1-page web app written in C#, using ASP.NET MVC 4 and Directory Services. It allows users to change their Active Directory password on their own, provided the user is not disabled. PassCore does not require any configuration, as it obtains the principal context from the current domain. I wrote this in less than 2 hours. There really was no free alternative out there so hopefully this saves someone else some time and money. IMPORTANT: If you are going to expose this web app outside your LAN, please use https
