    Yesterday during chapel I went over to Old Main in order to reboot an access point which wasn’t checking in. I got there, looked where the access point was supposed to be and saw two holes in the wall. I went back to my office and used some tools I created over the summer (I’ll…

    I have had a couple of people ask me today, “How fast is our internet connection?” The quick answer to that is 30Mbit I1 and 45Mbit I2.

    Over the weekend I upgraded our Wildfire Jabber server to the most recent version.  Now I believe that using our LDAP based groups will work much better.  Now if we could just get more people to use our own  Jabber IM server instead of AOL, MSN, or Yahoo…

    We just finished pulling more wire to places in Southwest hall where we are planning on putting wireless access points.  There will be 14 access points in all which will hopefully cover the entire dorm in a nice coating of 802.11g.

    Well, it was bound to happen.  Since I just recently finished upgrading SpamAssassin to version 3.1.2, they released 3.1.3 to fix a security hole.  So, SpamAssassin has been upgraded once again.  Here’s hopeing that this version is a good one.
