I really should be studying for my stat exam tomorrow, but I was logging into my.ucf to download my lecture notes, and while Blackboard Learning System (the really shitty replacement for WebCT) was stuck in an infinite loading loop (most probably caused by incompetent javascript) I decided to finally get Google Chromium (which apparently has an excellent javascript engine) working on my Sabayon Linux desktop.

So, xen is really beginning to piss me off. I turned off all my machines to do a snapshot, and when I tried to bring them back up, they were all in the ‘blocked’ state. Upon further investigation (using virt-manager/xm console), I found that they were hung at the “Checking for hardware changes” item in their boot process. This could be a CentOS/RHEL 5 issue, but I’m putting my money on xen.

I’ve been playing around with SELinux at work recently. Not surprisingly, I was struggling to get SELINUXTYPE=strict to work properly. Unfortunately, all “google results for ‘enabling selinux strict’ would return were dead ends. People would enable selinux strict, kernel panic, and ‘fix’ it by disabling selinux.
Well, a co-worker of mine *was* able to successfully enable selinux’s strict policy on RHEL5 (CentOS 5). He gave me this guide to post to the world for others to see how (thanks Mykola):

Hello world! I just updated my whole server environment and, my, things are looking good. Anyway, I had to run through these steps a half dozen times, so I thought I would post it here for myself and (maybe even) others.
Here’s the commands I ran to turn a clone of my base RHEL5 (CentOS 5.2) Xen image into another working virtual machine on my RHEL5 (CentoOS 5.2) Xen Host:

I recently reformatted my hard drive–switching from pure Gentoo to the Sabayon fork. Sabayon did for Gentoo what Ubuntu did for Debian. It’s generally a lot easier to use, but–unlike Ubuntu–it doesn’t sacrifice functionality for ease-of-use.

To a degree, I still actively work on my high school soccer team’s website (which I created back in 2005). I started working on it on and off since summer 2008, and 71 hours of development later, I finally pushed my changes to the live server in January 2009.

I’ve wanted to setup a serious linux-based firewall for my home network for some time now, and I finally got around to it yesterday.
There are TON of linux router distros out there, but instead of spending 8 hours picking & choosing, comparing & contrasting, nitpicking & debating, I asked someone else ;). Two buddies of mine have a similar setup at their homes: one uses Smooth Wall; one uses IPCop. I arbitrarily chose Smooth Wall (after actually setting it up, though, I think IPCop would have been a better choice–c’est la vie.
The installation is supposed to be quite painless, and it was–for the most part. The documentation and install process was intuitive and easy to follow, but it didn’t work OOTB. I probably only had so much difficulty because of hardware issues (fried NICs?) which is by no means Smooth Wall’s fault. Nevertheless, it took ~5 hours of bang-your-head-against-the-table troubleshooting ’till I could finally unhook the monitor & keyboard, shove it in a corner, and get some sleep.
I was also disappointed with two things that didn’t work as I had expected OOTB:

So, I figured: D-Link is a popular company, they’re not going anywhere, they sell tons of devices, so my chipset is probably well supported in Linux, right? Wrong.
