    If all goes well, we are planning on swapping out the very old 10 megabit hubs that connect all the dorm rooms together in Sohre Hall. We will replace them with nice new 10/100 switches that have gigabit uplink ports. We also plan on upgrading the dorms 100 megabit connection to a gigabit connection at…

  • IRC Bots

    There are more and more machines on campus infected by “IRC bots” every day. In an effort to stop them we began blocking all IRC traffic on the default IRC port of 6667 back in January. That has worked quite well, however the bots are getting smarter and using many other ports. In an effort…

    Well, after about a week of testing SpamAssassin 3.0, I decided I was ready to transition the college to the lastest version. In the past week I have been very happy with the way the new version is working. My only complaint is that they reduced the score for BAYES_99 to 1.9 instead of the…

    I am very excited to see that spamassassin 3 was released today. So far I have it installed on a test system and am having my email filtered through it. So far so good. Its only been filtering for 2 hours now, but it has already done a perfect job determining what is spam and…

  • Webmail

    As anyone who has used webmail.gac.edu lately knows, it has been slow. Especially during peak usage times (10:00am-10:30am). I think that I have found the reason things were running so slowly. The database that holds user preferences was slowing everything down. The webmail software (Horde) was making too may queries, and more importantly, too many…

    If you are wondering what happened to our network last week, here is a very good article from another college/university about an almost identical infection. http://www.bgsu.edu/offices/its/security/advisories/BGSU2004-08-27.html

    Sorry, wish I could update everyone but I am too busy and tired right now. As you probably know, a good sized virus outbreak occured on campus starting at about 7:20pm Monday night. Ok, back to work….

    Outdoor wireless coverage on campus should have increased significantly yesterday with the addition of another high powered wireless access point on the roof of Pittman Hall. That increases the number of these units to 3. One on Norelius, one on International, and one on Pittman. Now you can probably stroll all the way down hello…

  • Spamassassin update

    doachs

    Just in case anyone cares, I have updated our spam checking software (spamassassin) to the most recent version, 2.64. So far on my account it has resulted in spam getting even higher scores. I hope this update works as well for everyone else.

    For those of you who regularly use a wireless laptop or some other wireless device on campus, you may have noticed that we have lots of different wireless networks. In an effort to help wireless users roam about the campus from one access point to another, we have begun an effort to configure all the…
