Finding Independence

Technically, Independence Day in the US isn’t until tomorrow (July 4). I don’t plan on being around much tomorrow, though, so I’m posting this today.

New IE Flaws

In addition to the announcement of a new “trojan horse” for Mac OS X, a couple new flaws were uncovered and disclosed for Internet Explorer in the last few days as well.

Trojan Horse Exploiting OS X Flaw

Within the last couple of days, the Symantec Security Response web site posted a warning about a new Mac OS X-based trojan horse called OSX.Exploit.Launchd. This trojan horse supposedly takes advantage of a vulnerability that Apple patched with the recent Mac OS X 10.4.7 update (for both PowerPC and Intel Macs). This vulnerability, if exploited, can result in root access. But that’s not all of the story.

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.
