Although solen has been workin great for the past 180+ days, it looks like we have no choice but to reboot it. If you are wondering why, the reason is that netatalk has stoped working. Restarting the netatalk daemon does not appear to fix it. For some reason the afpd process just gets stuck. Hopefully…

Last night our res-hall network was extremely slow and flakey. There appeared to be lots of broadcast traffic and pings were timing out 80% of the time. After disconecting one dorm at a time, I discoverd that one dorm was causing the problem. I eventually traced it back to one network jack. Still not sure…

For some reason early this morning an email that was passed to spamassassin appears to have caused all of our spamd processes to lock up. Therefore email was not being checked for spam. This means you probably all got way more spam today that normal. Sorry about that. I have never seen spamassassin lock up…

Well, there have been lots of updates here at GAC today. First, this morning we updated our packeteer from 6.2 to 7.0 which gives us some new features and should provide even better packet shaping. Second, we upgraded all the hubs in Pittman to bran new switches. That should improve the networking in that building…

Add one more wireless access point on campus to the list. We now have a decent wireless signal inside the Guest House. Now we can actually offer our guests decent wireless internet access. Yay.

In our pursuit to ever increase our wireless coverage on campus, we have added an access point to Confer. Almost all of the 3rd floor of Confer and Vickner is covered well. On the second floor the middle 1/3 of the combined building is well covered. And on the 1st floor the very middle section…

The upgrade of networking hardware in Sohre apparently went smoothly. It took us about 3 hours to swap out the old hardware with the new. As far as I know, no comlaints. However as students come back from break later tonight and tomorrow, we’ll see how things go. Hopefully everyone will notice a better/faster network.

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…

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…
