Friday Maintenance

For the past few weeks the load on our email servers, specifically the ones responsible for imap/pop/webmail, have been unable to keep up with the increasing demand. Thus causing access to imap/pop/webmail to be unavailable during times of peek usage. Delivery of email was not affected. To help alleviate the issue, we have spent the […]

Daylight Savings Time

Since the time change for the end of daylight savings last month, our iCalendar files on the college calendar have been using the wrong time. This was caused by our usage of a constant timezone modifier for adding to event start times and end times. As a result, whenever someone had added an event to […]

Friday’s Upgrades

Every day it seems like we are sending and recieving more and more email. That means every day our email system is more and more loaded. A couple of weeks ago we hit the limit as to how much email our disks could handle for everyone’s inboxes. We store all the users inboxes on a […]

Horde, IMP, and imapproxy

So it turns out that the cache in imapproxy that we turned on yesterday has a problem. First of all, it seemed to work great. I think webmail was more responsive and there was a reduced load on our mail disks. However not all was well. It seems like some times when you deleted a […]

Email performance

As many people have noticed, email performance during our peak usage time (9:50am-10:20am) has been extremely poor. The main reason we believe is that the disk drives our email inboxes are stored on are just not fast enough. Currently we are using a Sun T3 disk array with a 1Gig cache and 9 fibre-channel disk […]

Shorter, smarter URLs

Today we began more widely implementing the mod_rewrite apache module to rewrite some of our ugly URLs. For example, the URL for a news story previously had been http://www.gustavus.edu/news/index.cfm?id=1658. That very same story can now be accessed at http://www.gustavus.edu/news/1658. Likewise, Eric Dugdale’s class schedule can now be accessed from http://www.gustavus.edu/oncampus/facultyschedules/edugdale instead of http://www.gustavus.edu/oncampus/facultyschedules/index.cfm?action=view&username=edugdale. While this […]

Replaced Switch

One of our HP 4000 switches had a bad fan that needed to be replaced before the entire thing overheated and died. Here is what Joel had to say about it: Dan and I replaced a switch in the Jackson Campus Center this morning. This switch is used by the Food Service, Health Service, Book […]

Automatic Proxy Settings

We just figured out that somewhere along the line, we broke automatic proxy configuration stuff. To fix it there are a couple of things we can do. First we added this to our /etc/dhcpd.conf file: option WPAD code 252 = string; option WPAD “http://www.gac.edu/cgi-bin/proxies”; In our old config we had option option-252 “http://www.gac.edu/cgi-bin/proxies”; but that […]

Strange Network Traffic

For some reason, since around midnight last night, there was a ton of broadcast traffic on our res-hall network. Around 150KB/s in fact. It was enough that wireless in my office was mostly unusable. Using tethereal I could see almost all of the traffic was coming from 2 MAC addresses and it was broadcast ARP […]
