    A little before 11:00pm tonight, one of our webmail systems started to have a problem. The other webmail server unfortunately was unable to handle the load all by its self and started to die as well. At around 11:30pm both webmail servers were back up and operational again.

    Just for fun, I put together a little time-lapse video of the recent snow storm as seen by our Stadium Webcam. If there are other days you think would make a good time-lapse video, please let me know.

    Our NFS server crashed last night at about 12:20am. As a result home directories were not available until our backup NFS server was in place at about 6:30am. At about 7:40am the main NFS server was back in service.

    Over the past couple of days we have increased the local network bandwidth available to some of the buildings on campus. By rearranging some of our network hardware and making use of previously dormant fiber links, we have made a few upgrades. Prairie View used to have a 100Mbit connection to the campus network which…

    This week we have upgraded the spam filtering software on our email servers from SpamAssassin 3.1.3 to SpamAssassin 3.1.6. We also added the OpenProtect SpamAssassin channel to our updated rules. This gives us the SARE rules which should help us catch more of the image based stock spams people see these days. If you are…

    This year we are doing a few extra things for our recent alumni. Since it has been well over 1 year since the class of 2005 graduated, it was time to deactivate those accounts and free up the resources they were using. One new service we are offering this year is the ability to keep…

    So, a tornado nearly hit Gustavus again. Apparently it just missed us. Some homes and power lines to the west and east were not so lucky. Here are some images: http://pics.smarp.us/main.php?g2_itemId=11509 Once the power went out, the generator that powers Olin hall and the server room is supposed to kick in. Well, this time it…

    Wireless is now in place in Southwest hall.  Yesterday Ethan, Joel, and I finished installing a total of 14 802.11g wireless access points, about 2 per floor per wing.  Initial testing shows that there is now good wireless coverage in most if not all of the dorm.  I was able to take my WIFI VOIP…

    This morning I upgraded our version of Spamassassin from 3.1.1 to 3.1.2.  No major changes with this release that I can see.  I also ran sa-update to get the most recent patterns and stuff.  Hopefully this will help it catch even more of those stock spams we are seeing these days.
