Eduroam Wifi Service

If you have used the Hopkins wifi or GuestNet system at Hopkins, you may have noticed a third option called eduroam lurking around in the "available networks" list. Aside from a quick email sent by the IT department sometime during the fall 2013 semester, stating that it is a new site for visitors to use while on the Hopkins campus, not much is known about the service. After some digging, the STS TechBlog is happy to help summarize the important information you need to know about Eduroam.

Eduroam as a name is made from combining two words: education and roaming. The idea behind the creation of eduroam in general is that visiting students are somewhere between a Hopkins student and a non-affiliated campus visitor, and therefore exist online somewhere in between the Hopkins wifi and GuestNet. The eduroam service is available to every student from any US institution, or more generally anyone who has an email address that ends with @.edu. CORRECTION: It can be used from any email address associated with a participating eduroam site, not just @*.edu.

The eduroam system is able to take the information from that visiting student's home institution and authenticate it on a server-system stored at Hopkins. It's also a way for the home institution to continue to provide free wifi access for computers and smartphones to their students, faculty, and staff, even when their affiliates are on the other side of the world!

Eduroam is managed by an independent company with academic partners all over the world. The company was started in 2003 by a task force at TERENA focused on mobility, specifically to provide "roaming network access across research and education networks." After a series of extensive tests in Europe (where the company is based), other countries and institutions started to join list of partners. In 2010 the membership group became so large that a Governance Committee was formed. This committee is made of nominated members from North America, Europe, and Asia-Pacific, which goes to show how far this company has spread in only 7 years. A list of world partners can be found at this link, and a list of partners in the USA can be found using this link. For more information on eduroam's formation or technical aspects, please visit their website.

If you are hosting a friend from another school at Hopkins, all he or she needs to do is set up her mobile device or laptop to recognize the eduroam system, and then sign in using her credentials. Remember how you had to change features and check off boxes to be able to use the Hopkins network? It's the same thing for eduroam with some minor adjustments. Note that these changes should be made according to the home institution's system, not necessarily the Hopkins system. 

You will need:

• TCP/IP: DHCP
• EAP type of the home institution
• Network authentication: WPA2
• Data encryption: AES
• Authentication method/protocol of the home institution
• Certificate authority of the home institution

When your friend logs in, he or she should use his or her full user ID at the home institution as the username and the password associated with that account. For example, the full username is jhopkin1@jhu.edu and my password would be laX.bro1876 (just saying). If you want to connect to the eduroam system at Hopkins as a Hopkins student, then you will need the following:

• TCP/IP: DHCP
• EAP type: PEAP
• Network authentication: WPA2
• Data encryption: AES
• Authentication method: MSCHAP-v2
• Certificate authority: Comodo/AddTrust External Root CA
• Server name: freeradiuspilot.win.ad.jhu.edu

To use eduroam at an institution in which you are the visitor, you will need to acquire information regarding the network authentication type and data encryption method of the home institution. Don't forget to use your full username! Everything else will be the same as if you were at Hopkins yourself.

Printing at JHU

If you’re a new student here on campus, chances are high that you’ve needed to print a few things out already, especially if you enrolled in an Expository Writing class this semester. If you or your roommate has a printer in the room, then you can rest assured knowing that you’ll always have a physical representation of your homework, right? Wrong. The inconvenient truth about technology is that it sometimes, for whatever reason, fails. Not all of these problems are permanent, but in a tense situation with time running out, it’s comforting to have a back-up plan.

For all the students who have forgotten or will ever forget to buy computer paper or printer ink over the weekend, Johns Hopkins created not one but several safety nets to assist you. The most easily found printing center is on M Level in the Milton S. Eisenhower Library, about 50 feet away from the Guard’s Desk. Before you print for the first time, you should be sure that you have either J Cash on your J Card or on a printing card, which you can purchase at the Circulation desk for cash or buy from the black box in the Printing Room with a credit card. If you only want to print black and white copies, you can use the main printing room. For color copies there is a room on A Level that you can use instead.

Prior to printing in the Printing Room, you need to tell the printer what it is you want it to print out. Immediately to the left of the red double doors outside the room are three computers that are for one purpose only: to handle all the printing needs of JHU students. These computers have most of the Microsoft products installed on them, and connections to the Internet through the Mozilla Fire Fox  browsers.

After locating your document on the computer, hit the print button. You’ll go through the normal menu items, and after you hit “OK,” you’ll be asked to name your printing job. It’s a good idea to use your last name because you’ll recognize it on a list, and it can be modified with numbers in the case of numerous print jobs.

After you’ve gone through these steps, you can go into the Printing Room and print your documents. Go up to a printer, swipe your J Card or the Printing Card, and the screen will change to a list of all the unfinished print jobs. Look for your print job’s name, check the box next to the job name, and hit the print button. Your account will be charged $0.07 per page; however, the MSE Printing Center prints double sided, so you end up using half the paper that you would have used otherwise.

The Library isn’t the only place on campus you can print either. AMR I, Wolman, and Charles Commons all have their own computer labs, called Residential Computing Clusters (RCC). Each contains nine pcs, two Macs, and two Laser printers, one of which is color. The Charles Commons RCC is equipped with six computers and one printer. The AMR I RCC is open to AMR I and II residents, while the Wolman RCC is open to Wolman and McCoy residents and the Charles Commons RCC to Commons residents.  There are also various computer kiosks around campus that are equipped to handle a quick-print task every so often. These printers require a small fee of $0.06 per page.

Of course, if you for some reason can’t physically get to the library or another printing center, you can always use wireless printing and print it out later. To do this, log on to the “hopkins” wireless network and go through the normal printing option windows. You should still see the “Enter print name” window by which you can identify your print job in the library. Whenever you’re ready to print, Hopkins is ready to handle it.
