Mac OS X v10.6 Snow Leopard – What’s the Timeline for Campus?

30-Mar-10: View an update to this post at DePauw now supports Mac OS X v10.6 ‘Snow Leopard’.

Information Services does not yet provide support for Mac OS X v10.6. We recommend that you do not upgrade to Snow Leopard until later in the year.

Our research has shown that the Novell Netware network does not currently support Mac OS X v10.6 and the following network applications will NOT work:

* The Groupwise email client
* Printing to departmental or public networked printers
* Using aliases to access network drives (P:, I: and U:)
* Groupwise messenger

What’s the timeline?

According to Novell’s support timeline, updates that will make Netware compliant with Snow Leopard will be available sometime in mid-Fall. After those are available and we have confirmed that OS X v10.6 works on our network, we will notify the campus and begin providing support for it at that point.

Once we are prepared to support Snow Leopard, our campus license will allow us to install it on any University-owned computer that meets the minimum system requirements noted by Apple ( Students can purchase the upgrade directly from the Apple Web site.

What if your new computer came pre-installed with Snow Leopard?

If your new computer came already installed with Snow Leopard or you have already upgraded to Snow Leopard, following are alternative methods for using some of the network applications that are not compliant:

* DePauw e-Mail –Use
* Accessing network drives (P:, I:, U:) – Use
* Printing to networked printers – Email the document to yourself, then use a public lab computer to print it

Spam Filtering at DePauw

Contributed by Michael Gough, Instructional Technologist and Coordinator of START and Bernie Timberman, Senior Network and Systems Administrator

Spam is becoming more prevalent in the cyber community every day. Many viruses and identity thieves rely upon spam email to spread their schemes. Therefore, to prevent many viruses and possible spyware infections, DePauw has invested in two robust spam filters. These filters work very well, especially given the volume of emails that come into DePauw. However, it is not perfect and users should still scan attachments for viruses and spyware. Also, be careful when clicking on links in emails; many spammers use these links to take you to Web sites that can steal information from your computer.

The following offers a perspective of how much of our email really is spam, helps you understand how this system works, and give you an idea of how your contributions can assist our spam filter system.

DePauw uses two Barracuda Model 400 spam filters to trap spam, viruses, and Denial of Service attacks. Denial of Service attacks are email attacks that are designed to overwhelm an email server and deny its functionality for its users. Our filters are configured to update their spam and virus definitions hourly. This information is combined with known spam messages identified by the HelpDesk. Below is a graph from one of the filter’s recent performances.


Notice how only a very small fraction of the total is allowed to be delivered to the recipients’ email boxes. The spam filters actually have a 12 step defense layer and a load balancer equalizes the work between the two filters so that one of them is not overwhelmed with too much volume.

The last step (Spam Scoring) is modified daily by the DePauw community. We input spam messages that are received by the HelpDesk from users to strengthen the spam filtering. Therefore, you can help our filters become more efficient by sending any spam that you recieve to the HelpDesk. This will help all computer users prevent viruses and cybercrime on DePauw’s campus.

Laptop Initiative Update

Contributed by Courtney Hime ’09, ITAP Communication Consultant

As spring approaches, it’s time for the Laptop Advisory Committee to make the final decisions about the new models of laptop for the incoming class of 2012. Mike Moore, director of the Laptop Advisory Committee said they are in the process of finalizing the negotiations with Dell and will begin to create the image (compilation of software) for next year’s model.

Every year the image writers work with Dell to ensure that all the necessary software is installed onto student computers, while at the same time making sure to keep the personalized experience of getting a new computer intact.

Since the laptop initiative began, the basic image of the computer hasn’t changed. Each model – or software package for Apple users – consists of the core operating system, the Microsoft Office suite, Macromedia suite and antivirus software. The incoming class of 2011, for the first time, also received the GroupWise e-mail client on their computers. Novell (network software) isn’t installed with the image, however, because students cannot connect to the network unless they are on campus. There is, however, a huge campaign to install Novell when students arrive on campus.

Last spring, the Laptop Advisory Commitee was faced with the decision of whether or not to upgrade to Office 2007 from Office 2003. Office 2003 is unable to read Office 2007 .docx files, so if they decided to upgrade campus, transferring files could, and would likely, prove to be a challenge. Ultimately the committee decided ro move forward to get campus oriented to the new software, a decision Carol Smith, Associate CIO for Instructional and Learning Services said she was happy with in the long run.

Smith said the Office 2008 upgrade for Apple users should be available to Mac users before the end of the semester. The team is finishing up the testing phase, but the plan is to have software upgrades ready for campus before students leave in May.

The team is now faced with the dilemma of whether or not to embrace Microsoft Windows Vista for next year’s image. Smith said they haven’t made a decision yet of whether or not to upgrade, but will be finalizing that as they finalize the image.

Here’s “What’s New” in Information Technology this fall!

1) Simpler logins: When accessing your network drives through your browser, you now simply enter your username in the username box at No more student.depauw or faculty.depauw!

2) University Calendar to GroupWise Integration using iCal: Click the Add Calendar Event Icon next to an item on the University Calendar, enter your e-mail address, and click the Send button. The Event is automatically sent to your GroupWise calendar.

3) Moodle: Moodle is DePauw’s new learning management system. Moodle is like BlackBoard but is developed from a more learning-centric perspective than Blackboard. It enables faculty members to easily set up interactive, online course communities and materials for classes. During the 2007-2008 academic year, both Moodle and Blackboard will be available for faculty members to use for their courses. Beginning Fall 2008, Moodle will be the sole CMS (course management system) for campus. FITS will offer training and support throughout the year to help you learn how to use Moodle and migrate old courses to it.

4) Expanded wireless coverage: We now have wireless coverage in the West Neighborhood Duplexes as well as expanded coverage in North Quad, specifically Mason Hall. And expanded coverage is coming soon to South Quad!

5) Microsoft Office 2007: Microsoft Office 2007 is installed on first-year students’ Dell program laptops and will be available to others on campus later this semester – watch for details.

6) In the continuing fight against Internet e-mail spam, we have begun a new strategy to facilitate electronic communication. Register legitimate e-mail addresses by sending them to the newly created e-mail account,

7) Consolidation of email usernames/passwords: We are moving toward using e-mail usernames and passwords for more services. To date, we have added ILLiad, the Interlibrary Loan request software, to the list.

8 ) Data Center Web Page: You may have seen news about companies like Google, and the rising cost of heat and air bills in their data centers. We are happy to report that the University has reduced the size of its data center over the past year. In case you want to know more, the DePauw Data Center has a Web Site at


9) I-Light update: DePauw has been on I-Light, the Indiana Fiber Network, for six months. I-Light provides increased bandwidth to Higher Education institutions in Indiana, as well as institutions connected to Internet2.
