Samba 4 as an Active Directory Server – Can it dance the dance?

Two weeks ago I thought to myself ‘Gee, now that Samba 4 has a real release out, wouldn’t it be fun to test it out and see how it holds up?‘ And so my adventure began. Now mind you, I’m not a novice to Samba, or to Active Directory, so I figured this would be a simple setup and test. How hard could it be?

Logical Repair Practices

Tuesday, 29. May 2012

My God, can it all be the same?

Seems like most of my job now a days is looking at large systems and isolating problem areas. Things like performance problems, data corruption, or even failure analysis. Many of these systems have several independently managed processes, all tied together in a single forward facing application. Over the years, I’ve developed some methods of approaching system failures and problems that gives me a better chance of quickly evaluating and repairing the issues that plague these systems. I used to believe that these methods were only valid on larger system models, then, one day, a colleague of mine and I were sitting in a small coffee house discussing a problem they were having with one of the desktops they manage. While we exchanged ideas, I suddenly realized that I was using the same mental process on this little desktop as I did with the large cluster systems.

Open Source Groupware – SOGo

Monday, 1. August 2011

Open Source Groupware – The Clear Leader is SOGo:

Some of the early groups of articles I penned on this blog, were comparisons of Open Source Groupware projects. At that time, the only one I could really recommend was eGroupware. Although I still believe eGroupware is a valid contender for your Groupware server, I have discovered a project, that in my opinion is leaps and bounds ahead of the pack. The project is called SOGo.

SIP Brute Force Attacks Escalate Over Halloween Weekend.

Monday, 1. November 2010

SIP brute force attacks escalate over Halloween weekend.

Looks like the bad guys were up to no good again this weekend. SIP based PBX operators reported a huge increase in bogus registration attempts against their systems over the Halloween weekend. Our hosted PBX farm experienced this increase first hand. Logs showed an attack from a new and unique IP address about every minute. At the end of the weekend, over 1300 unique IP addresses were logged.

Setting Up Native IPv6 Connectivity, A Network Operators Overview.

Friday, 2. July 2010

Setting up IPv6 connectivity.

Back in December `09, my company ACT USA, began testing IPv6. These tests quickly advanced to our production environment. Over the last six months, I have been in the process of setting up native IPv6 connectivity for all our data centers. This connectivity is based on the dual stack model. This article attempts to cover the technology available, and the choices I made based on that technology.

Building Redundant Networks in Data Centers

Building Redundant Networks in Data Centers.

I recently was asked to put together a brief web presentation on the different methods of creating redundant networks. I couldn’t think of a better place to put it, then right here on my blog. After all, I was overdue for a post anyways…

What do I mean by redundant networks?

A redundant network is two or more distinct paths for data to travel to and from an upstream network. In it’s simplest form, it can be a piece of equipment that can be manually placed into service easily upon a failure. More often though it is set up so that any single device or connection can fail, and without user intervention, a backup system or connection will automatically step in and take over the job of the failed device, or connection. A redundant network does not mean that no mater what happens, your data will still be reachable. There are many factors that need to be considered, ranging anywhere from your providers, to your applications, that can cause a failure.
