Bulk Adding Entries in DNS

While we are on the topic of bulk changes—I’ve discussed bulk changes in Active Directory and bulk adds to a WINS server—I thought I might discuss bulk adds of resource records to a DNS zone.

Mounting ISO Images in Linux

Here’s another incredibly simple task that one often needs to perform when using Linux: mounting an ISO image. The problem is, I so very rarely do this that I forget the exact switches to use. So, to avoid that problem in the future, I’m posting the information here for future reference. Even if no one else finds it useful, at least I’ll know where to look next time I need to do this.

Strange ESX Server Error

I spent the day today working with ESX Server 3.0 and VirtualCenter 2.0, the next-generation products from VMware. After shutting down one of the older ESX 2.5.3 servers in the test lab and then booting it back up again, I ran into an error trying to start some of the VMs.

Automating Static Entries in WINS

There may be times when large numbers of static (or dynamic, for that matter) entries need to be added to your WINS server. This may be the result of migrating from one WINS server to a new WINS server. In any case, here’s the commands needed to do just that.

Available Exploit Code for RRAS Vulnerability

Exploit code that takes advantage of the security flaws patched by Microsoft’s recent MS06-025 security update has been made available (see also this article). The exploit code was made available as part of the Metasploit framework, an open source tool for penetration testing and vulnerability assessment.

WinFS Axed

The news is all over the ‘Net: Microsoft has killed WinFS as an independent product and will instead roll the technology into the next version of SQL Server, code-named “Katmai.”

NetApp ONTAP Simulator and ESX Server

In preparation for some NetApp training that I’ll be attending next month, I downloaded the NetApp ONTAP Simulator. The ONTAP Simulator runs on top of Linux (a few different distributions are supported) and allows you to simulate a NetApp Filer. This is pretty cool for a couple of reasons, not the least of which is that it allows you to perform testing of NAS and iSCSI operations without having an actual Filer. Unfortunately, I had some problems getting the ONTAP Simulator working in a virtual machine on VMware ESX Server.

New Apple Store

The new Apple Store in Raleigh opened yesterday at Crabtree Valley Mall. I had started to mention this on my weblog yesterday, but initially dismissed the idea. Then I saw this article, and decided, “Hey, I’m not the only one that was excited about the new Apple store!”

Very High Quality vs. Just Good Enough

In a recent article discussing Novell’s leadership change, one analyst was quoted regarding the change as being positive for Novell in that they (Novell) could stop building very high quality products and instead build products that are just good enough. I don’t know about you, but this spirit of mediocrity is exactly the wrong kind of thinking for IT vendors.

Apache as an OWA Front-End

A while ago, I discussed the use of Apache to protect OWA from web-based attacks. This configuration placed an Apache HTTP server in front of a server running Microsoft Exchange Server 2003 to protect it against web-based attacks, offload SSL encryption, and enable name-based virtual hosts (for the conservation of public DNS hostnames, especially important for smaller organizations). While this is a useful configuration, it is not without its drawbacks.
