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?

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.

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.

The debate regarding some of the visual changes, as well as the new services tied to Canonical, has caused a minor tremor through the open source community.

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.
