WolfieNet Arrives in SB Residence Halls

Tuesday, August 25th, 2009

A major network upgrade took place this summer. New network switches and wireless access points were installed in the student residence halls. Students can now connect to WolfieNet, the wireless (Wi-Fi) network, from their dorm room. WolfieNet features:

  • Latest encryption technology to protect student computers and data.
  • NetID and NetID password required for authentication.
  • No need to bring a wireless router to campus anymore.

More information, including how to make a connection to WolfieNet, can be found on the Division of Information Technology Web site.

 

Connecting to AirNet Using Ubuntu Linux

Friday, November 14th, 2008

One of our student technicians in Client Support documented a simple guide for connecting to AirNet using Ubuntu Linux and posted it as a comment to our Understanding Campus Wireless entry. He says these concepts work for other distributions, but the commands may be different.

Our boss was impressed with these instructions (and the fact that our student used his MySBfiles to document this). We decided to pull his comment out of the obscurity of the 50+ remarks we received and made it a blog post unto itself in the hopes that it might reach a wider audience and someone might find it useful.

Way to go, Addisen!

iPhone Mania Hits Stony Brook!

Tuesday, July 17th, 2007

 

 

 

 

 

 

 

 

 

 

 

Members of the Client Support staff enjoy friendly, back-and-forth banter about which is better … Mac or PC. We have three staff members, in particular, who laud the prowess of all things Apple.

Lindsay is one of those people. She had everyone in the office talking when she returned from her vacation out west with an iPhone. For many of us, this was our first time seeing one LIVE, up close, and in person. I sheepishly asked if I could hold it. She told me not to feel embarrassed. Apparently, I wasn’t the only one who made such an odd request. Lindsay pointed her way through different screens like she was Steve Jobs. I watched in awe as she tilted the phone to its right to show me a video being played in horizontal screen mode.

"Where is this all going?" I wondered to myself and will I one day own an iPhone of my very own? Not for another two years, at least. I just renewed my Verizon Wireless contract and upgraded to an LG VX8600. I’m so yesterday’s news.

Anyway, we urged Lindsay to blog about her iPhone discoveries because students will undoubtedly be coming back to campus as proud owners of iPhones this fall. Lindsay agreed to share her test results with me, so here is what we’ve learned.

The iPhone will connect to AirNet, the service that provides campus wireless access to Stony Brook University faculty, staff and students. You can log in through the web for limited network access with no problem. This will let you surf the web a lot faster than AT&T’s Edge Network will allow you to. The downside is that you can’t send or receive email while using AirNet’s limited network access.

You can connect to Stony Brook’s VPN (virtual private network) to gain access to your email through the mail client on the iPhone.

This is how you connect to the VPN:

  • Hit Settings on your iPhone’s main menu.
  • Scroll down and select General
  • Next, click on Network

You will come to a screen that looks like this:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  • Click on VPN
  • Select Settings underneath
  • Choose PPTP
  • Enter server address:  pptp.airnet.stonybrook.edu
  • Account name is your NetID
  • Password is your NetID password. You should get an alpha/numeric keypad to type this in.

There appears to be a glitch that occurs when your phone goes to sleep (when this happens you lose your connection to the VPN) or if you leave the VPN and come back to it at another time. When you go in again, you have to turn your VPN on and repeat the above steps. Otherwise, you will only get a numeric keypad to type in your NetID at the password screen when you try to use the VPN shortcut. You will not be able to type in alpha characters.

Lindsay’s way around this was to go into Windows and change her NetID password to all numerics. You don’t have to do this. In fact, we do not encourage it. You can go back into the VPN Settings each time to put in your NetID password without changing it. Our Division of Information Technology Security Officer advises that an all-numeric password is very insecure and should not be used as a password on any Stony Brook University system.

Lindsay said a lot of people with iPhones are encountering this bug. It is currently being discussed on some forums.

We’ll wait for the software update and in the meantime keep asking Lindsay if we can hold her iPhone!

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!
