OPENXTRA is a UK VAR that offers a variety of network management and server room monitoring tools and information. They publish a set of related newsletters, including one on Network Management, although there don't appear to have been any issues published in the last few months (since December 2004).
I haven't read all the articles on their web site yet, but the ones I've looked at so far all seem fairly introductory and high-level; for example, An Introduction to Network Configuration Management is a good very high-level overview of what network configuration management is and why it's useful, but it's fairly short on details. Regardless, I'm glad to see them making these articles available.
Hi Brent,
One of my colleagues forwarded your blog and I'm glad that you have mentioned openxtra as a source of useful information - our intention is to give readers no nonsense overviews of network management topics in plain language and i hope we achieve that. I just wanted to say that the newsletter runs a distribution list who receive newsletters twice a month. Past newsletters to current date have now been updated on our website for viewing.
