How can I connect to AirPennNet with my Linux laptop?
With KDE, Gnome, and Unity based distributions like openSUSE, Fedora, and Ubuntu you should be able to connect to AirPennNet using the built-in graphical network utilities. When you go to add 'AirPennNet', please utilize the following parameters:
- Security: WPA2 Enterprise
- Authentication: TTLS
- Inner Authentication: PAP
- CA / Certificate: Use System CA Certs if available.
- Username / Password: your PennKey credentials
If you are having problems connecting, first attempt to connect to AirPennNet-Guest to verify that your wireless hardware is in-fact working. If you continue to have issues, when you proceed to contact CETS please provide the following information:
Below are some issues we've come across in our community. You may have to look at your Linux distribution's documentation for specific instructions on fixes.
- Jan 2014 - There are known issues with some Linux wireless drivers and 11n frame aggregation used on campus wireless equipment. Unfortunately, this seems to be a problem with the Linux drivers thus far. We are testing disabling 11n frame aggregation within the SEAS buildings - if your machine works in SEAS but no where else on campus, there is a good chance you are afflicted by this. A work-around for certain Intel wireless chipsets using the 'iwlwifi' kernel driver involves disabling 11n support via the '11n_disable' parameter. We are also seeing issues with some Realtek drivers (RTL8188CE) that we haven't determined a good work-around yet.
Information needed for CETS support:
- Your version of Linux ('cat /etc/issue')
- A copy of your log files. You can provide us a filtered version if you are privacy conscious.
- The output from terminal of the following:
These are generic instructions for configuring a linux machine to work with AirPennNet. Please note these are general guidelines and you might need to alter them for the files in your specific distribution. FYI - If you are having trouble with Ubuntu 12.04+ you should not be using these instructions.
- You need an 802.1X supplicant. Many versions of Linux come with wpa_supplicant. Put the following text in wpa_supplicant.conf. This file might be in /etc/wpa_supplicant.conf or /etc/wpa_supplicant/wpa_supplicant.conf or similar location:
- Edit your network interfaces file to refer to wpa_supplicant.
Example 1: Ubuntu
The interfaces file would be /etc/network/interfaces.
The following text goes under the wireless device section of this file:
Example 2: Gentoo
The interfaces file might be /etc/conf.d/net
The following text goes into this file:
- In one window, start the command
- Bring your wireless interface up. Do this with ifup or ifconfig, however you typically start your interface
- In the wpa_cli window, issue the password command:
password 1 <your pennkey password>
