OpenBSD 3.8

It’s hard to believe that I’ve been posting articles here for this long, but it’s time for another release of OpenBSD. As I’ve mentioned here before, I do use OpenBSD for a few purposes on my network, and I’m confident that OpenBSD 3.8, due November 1, will find its way onto the network as well. (It’s fairly likely it will quickly replace OpenBSD 3.7.)

Shelob (or Ungoliant)

This story about the University of Indianapolis and their home-grown system for quarantining PCs infected by spyware or viruses is really interesting. Named Shelob (and soon to be renamed Ungoliant to prevent a conflict with another open source project), this system really works. Today. How is it, then, that a group of IT staffers at a university can come up with a system for network access control, but multi-million dollar companies like Cisco and Microsoft can’t? I could say that this is a testament to the value of open source software, upon which the solution is built, but that seems fairly obvious.

I Want One!

The new Sun “Galaxy” x64 servers (the Sun Fire X4100 and Sun Fire X4200) are wicked cool. Hot-swappable 2.5” Serial Attached SCSI (SAS) drives…dual-core AMD Opteron CPUs…quad built-in Gigabit Ethernet ports…it’s enough to make me want one. Even better, they run Windows, Linux, or Solaris (all fully supported by Sun, too). It’s almost like having your cake and eating it, too.

Technology Convergence

It’s about time. I’ve been waiting for someone to take revolutionary (in my opinion, at least) technologies such as virtualization, blade servers (or any alternative server form factors), and thin-client access and combine them. And that’s exactly what IBM, VMware, and Citrix are doing, as discussed here.

Protecting Against OpenSSL SSLv2 Flaw

The recent flaw in OpenSSL (versions prior to 0.9.7h and 0.9.8a) highlights the fact that SSL is not a security panacea. (You can get more information about this flaw from the link above, from this eWeek article, or from this Netcraft post.)

Bluetooth Interfering with GPRS on my Treo 650

Some time ago, I noticed while using my Treo 650 that I could not perform a HotSync operation via Bluetooth while I had a GPRS connection active. As if that wasn’t enough, I’ve discovered what appears to be a further incompatibility between these two wireless technologies.

Just in Case

I’ve mentioned the bug discussed in KB905809 several times in this blog. In reading those posts (or reading the KB article), you’ve probably seen that you can use the SC.EXE command to set the security descriptors on the Service Control Manager to fix the bug. What happens, though, if you mess up the SC.EXE command?

An Interesting Viewpoint

I don’t know that I necessarily agree with his viewpoint, but in “A fake freedom”, the question is raised: Do we really own our data?

Open Source on Mac OS X

Most people automatically equate “open source” with Linux or Apache. But there’s more to open source than that. There are a wide variety of open source projects that are also targeted at (gasp) Microsoft Windows and Mac OS X.

Moving Back to Desktop Manager

Over the last few days or so, I have been experimenting with Virtue, a virtual desktop application. I’ve used various virtual desktop applications since switching to Mac OS X (see this blog posting). After getting used to the lack of a desktop pager, I was really beginning to like Virtue and it’s functionality, even though it seemed as though the Virtue project had slowed and/or stopped development. Finally, after searching around for some way of re-instating the “Run Application” feature in Desktop Manager, I found that Virtue was incompatible with Mac OS X 10.4, aka “Tiger.” Since I’ve been researching the possibility of an upgrade to Tiger, I decided I’d better switch back to an application that was supposed to run under Tiger (which, based on what I’ve been able to find, Desktop Manager does).
