Beware of Walking Laptops

Wednesday, June 20th, 2007

Stony Brook University is beautiful in the summertime. Soft breezes rustle the leaves of the trees near Roth Quad. Sunshine warms the faces of students reading texts on benches outside the Melville Library. The scent of rose, lily and honeysuckle permeates colorful garden landscapes surrounding the Union.

There are fewer individuals milling about the grounds. Students are off doing summer internships or working summer jobs. Faculty travels abroad to conduct research. Staff members engage in professional development by traveling to other cities to attend conferences and workshops. Fewer eyes are on the lookout.

You don’t often hear about crime at Stony Brook. It’s a relatively safe campus year round, but it feels especially safe and secure during the summer months. It is natural to let your guard down in this easy-going, airy environment.

Thieves are counting on you to do just that.

Client Support has been made aware of several laptop thefts on campus in recent weeks.

So, as a reminder:

  • Do not leave your laptop unattended, especially in public spaces like the library or Student Activities Center.
  • Make sure you lock the doors to your room or office if you need to step away from your machine.
  • Try not to leave your laptop out in the open. Keep it out of sight, in a drawer or a cabinet.
  • Think about buying a lock for your laptop. Seawolves MarketPlace sells several in the range of $25 - $42.
  • Be careful about leaving important data on the computer. It is always a good idea to back up your data in other places anyway, but in this case, you do not want sensitive information getting in the hands of the wrong person.
  • If you see something, say something. Call Stony Brook University Police (631) 632-3333 to report a stolen laptop. You can dial 911 from any campus phone.

Understanding Campus Wireless

Friday, June 1st, 2007

Being the "wireless and web guy" has brought something to my attention. People don’t know anything about AirNet! AirNet is what we call the wireless infrastructure on campus. So, let’s hold hands and dive into the wonderful world of AirNet.

How AirNet Works (Mac/PC): 
It’s helpful to understand a little bit of how AirNet works in order to diagnose problems down the road. AirNet is an open wireless access point. Open as in, anyone within range can connect to it. AirNet does not require a connection password, not in the same way traditional access points do. When connected to AirNet, the user is limited to loading sites which relate to getting authenticated on AirNet. (i.e. the AirNet Welcome Page the user sees in a browser shortly after connecting)

We do not set up a password in order to make sure everyone can see the Welcome Page. At the Welcome Page, we separate those who are AirNet veterans from those who are new to it.

Here is what some of these terms mean:

Connection: Being within the range of an AirNet access point. This results in a successful wireless transmission between the wireless device and the AirNet access point.

Authentication: Refers to being identified on the AirNet network as an authorized user through the use of a NetID and password.

To Summarize:

1.       Anyone that is within range can connect to AirNet

2.       Once connected, the only accessible Web page is the AirNet Welcome Page

3.       Finally, the user will fall under one of three categories:

  • Student, faculty or staff member who knows what is required to get online through AirNet
  • Student, faculty or staff member who is new to the system and needs some help getting authenticated
  • Someone who is not a student, faculty or staff member and is looking for a free ride. (Not happening on our watch!)

The AirNet Welcome Page
This will be the first page a new AirNet user will see when opening their web browser. Here the user can get more information on AirNet, log on to AirNet and also download the AirNet Client. Using the AirNet Welcome Page to log on is not recommended as it only grants the user partial access; the AirNet Client is a better option.

The AirNet Client
The AirNet Client is a small program that can be downloaded from the AirNet Welcome Page. This program allows the user to get authenticated without having to run into the AirNet Welcome Page. This gives the user two advantages: faster authentication and full network access (more on this below).

Partial Network Access vs. Full Network Access
Partial network access is what you are granted when using the Welcome Page to get authenticated. What this means to the user is that only the web browser is allowed online; the rest of the user’s machine is offline. Therefore, other programs like AOL Instant Messenger may not work. The user can get full access through the AirNet Client.

So, there you have it. Happy surfing!
