  • Slow email

    Late in the day yesterday (~4:00pm) the disks attached to our email server had a hiccup which caused a mirror system to fail. Thus the server needed to repair the mirror. Over the next several hours email was extremely slow. Users with small mailboxes (a few megs or less) were able to use email. Everyone…

  • Webserver downtime

    Our mail website http://www.gustavus.edu was not functioning for a few minutes this morning because it could not contact its database backend. Turns out a loose network cable was the culprit. Guess that is just one more reason why we are rebuilding the server room this summer and cleaning it up a bit.

    As some of you probably already know, there are new updates to Firefox (web browser) and Thunderbird (email client) that fix serious security issues. I encourage anyone using a version older than 1.0.2 to upgrade. Firefox version 1.0.2 can be found here: http://www.mozilla.org/products/firefox/all.html Thunderbird version 1.0.2 can be found here: http://www.mozilla.org/products/thunderbird/all.html Hopefully they are cached…

    Well, yesterday morning I got the official word that Pat was leaving Gustavus to pursue another position up in the cities. I wish him best of luck and that he will definately be missed here. I worked for him a number of years ago, and it was always fun. I also believe that without him…

    I just wanted to let everyone know that we are putting a new email server into place as a secondary to solen. This new email server has been configured to better combat spam by enforcing mailservers to adhere to the email standards more strictly. It will also pass all the email through an email scanner…

  • Webalizer spam

    doachs

    This is probably something others have already noticed years ago, but I just came across it this week. For a year or so now we have been keeping statistics on some of our web servers by using the popular Webalizer software. You can usually view a sites stats by adding /usage at the end of…

  • Wireless in Lund

    In preperation for tonights game, we have added a wireless access point to Lund. It is a nice, strong, wireless device that should cover a rather large area pretty well. If anyone uses it, I’d like to hear about your experiences. It is a little bit of an unusual setup for us because it is…

  • Res Hall Traffic

    Something strange happened on our res-hall network again this morning. At about 7:00am this morning there was a ton of broadcast traffic. Something like 50k or 60k of traffic where we normally see about 5k-10k. Another symptom was that all of the switches in the dorms were seeing really high cpu usage. Especially the slower…

  • Spamassassin server died

    One of our two spamassassin servers stopped working Saturday at about 9:00am and was not fixed until 8:00am Sunday morning. During that time about half of all email being sent to spamassassin was not being checked and was just delivered instead. So you probably saw a big rise in spam in the past 24 hours.…

    As of about 6:00pm tonight, our internet bandwith has doubled from 10M to 20M. It’s probably maxed out by the time I finish typing this, but oh well. Was good while it lasted 🙂
