1. Heartbleed

    Heartbleed.

    And the Lord said, "Thou shalt patch thine servers. Posthaste."

    This is the real deal, folks. The general zeitgeist in my sysadmin circles is that this is the most severe, widespread, high-potential-for-damage bug in a decade. If you're running a vulnerable version ...


  2. Implementing IPsec Transport Mode

    I've been working with IPsec for many years, mostly in tunnel mode, when building LAN-to-LAN VPN connections or for mobile worker VPNs. Recently, though, I had occastion to venture into using IPsec in transport mode, which I'd never done before. In the standard tunnel mode, entire packets are ...


  3. UML --> Xen. Very cool.

    The virtual server that I've been renting from Linode for several years has up until today, been using User Mode Linux (UML) for machine virtualization. Linode recently launched a beta testing program for a new Xen virtual hosting system. I signed up this evening and migrated my server over ...


  4. 16-way Windows Box? You don't see this very often.

    Yesterday we received, at work, a new server which will soon be tasked with running a high-load, SQL query intensive application. It's a Quad-Intel Dual Core 2.66 GHz machine w/ 8GB of RAM and two 280GB RAID10 arrays. Since each of the 4 CPUs are dual-core, there are ...


  5. SSH brute force attacks

    I know there are a few of you out there that admin linux boxes either for hobby or work, so I thought I'd pass this along...

    If you pay any attention to your syslogs at all (which you should), you'll already know this, but in the last year ...


  6. pfew - that was *close*

    Our webserver at work went unresponsive a few minutes ago, and I thought I was going to need to reboot the thing, which would have been a shame:

    erika@lpdweb erika $ uptime
     14:46:55 up 299 days, 14:21,  1 user,  load average: 0.06, 0.09, 0.07 ...


  7. greetings

    Yeah - it's been a while since I've posted, so I figured that I should give an update...

    The last week or so has been good - stuff is pretty busy at work, and I've had a few large projects on my plate. One of which has been moving ...


  8. perl zealots

    Okay - I've always known that there are some rather intense perl zealots out there. Only today did I realize how fanatical they can become.

    Case in point.

    This guy made a linux distro in which the only compiled piece of code is the linux kernel itself. The rest of ...


  9. New toy...

    Well I finally caved in and picked up a Roku SoundBridge last night. A few of my co-workers have them and have been raving about them for a few months. I picked it up at Best Buy, and upon arriving home, it took me all of 5 minutes to get ...
