    For some reason over the weekend a bunch of IMAP and POP3 processes got stuck and made it such that those users could not modify their inbox.  I didn’t have a good way to figure out who those users were so I killed all IMAP connections.  Therefore this morning a bunch of people will probably…

    For anyone who is browsing the internet with Internet Explorer you should be aware that an exploit for a recent vulnerability is being seen on the net.  At this time there is no patch for this from Microsoft.  However if you turn off Active Scripting, you can prevent your browser from being exploited. Internet Storm…

    At about 12:35pm today, both of our servers that provide home directory access and email access (woof and meow) decided to call it quits and kernel panic. Both were restarted by 12:55pm. Luckily downtime was not too great, but it is very troubling that they both died when they did. No word yet on what…

    Wireless Updates: The big news this week has been wireless. Since the last update we have added wireless to Rundstrom and Norelius. From our stats, it looks like the students in Norelius are really making use of it. (110 devices in the past 24 hours) We also ordered another 60 access points due to arrive…

    Late yesterday afternoon we were hit with a particularly large batch of spam comming from computers spread all across the internet.  Then, due to a slight loophole in our mailservers configuration for blocking spam, the spam ended up in a loop taking up more resources that it otherwise would have.  The end result was that…

    Our old WINS server (phoebe.gac.edu) was just not doing the job right these days. In an attempt to improve windows networking on campus this morning we switched to a new WINS server (wins.gac.edu). Our new setup also includes a WINS proxy to help all of our subnets talk to the WINS server in as efficient…

    In an attempt to keep up with the ever increasing demand for more internet bandwith, today we increased our connection from 20Mbits to 30Mbits.  Enjoy the extra speed while you can.  I’m sure the students will find plenty of uses for it come next week 🙂

    For some reason or another the sound effects for my iChat client don’t seem to work all the time any more. I first noticed it last week. Shortly after the upgrade to OS X 10.4.4 I lost the sounds that let me know when someone has left me a message. I can quit iChat, I…

    At about 2:20pm our cluster died.  It was back up and running by 2:30pm. One of our cluster computers died, taking email and home directories down with it.  We discovered an issue which was causing the other half of the cluster to pause and not respond to email and home directory requests.  That problem should…
