Connect to wireless on Linux
The Colorado College wireless network uses the WPA2 protocol with AES encryption and PEAP authentication - your wireless card will need to support all these protocols in order to connect (most newer wireless cards are just fine). Instructions are as follows:
Ubuntu
1. Click on the wireless icon at the top right, and select “Connect to other wireless network.”
- NOTE: Ubuntu’s built-in wireless manager is nm-applet (Network Manager), currently at version 0.6.5.
2. For the Network Name, type “tigernet2″ (without quotes), and then select “WPA Enterprise” from the Security drop-down menu.
3. In the WPA Enterprise security window, type (again) “tigernet2″ for the Network Name, and then type your CC username in the “ID” field and your CC password in the “Password” field. You can leave the other boxes at their defaults. Once you select these settings, wireless should connect. Note, though, that it can take up to one minute for Ubuntu to authenticate your wireless card to the Colorado College network.
4. Open a web browser and it should take you directly to the CC registration page. If this doesn’t work, try entering the address manually: http://computerregistration.coloradocollege.edu
Non-Ubuntu, Using WPA supplicant
1) Download the root certificates from our website at:
https://secure.coloradocollege.edu/VerisignRootDER.zip (right click and “save as”)
a) Unzip the root certificates file you just downloaded
b) Copy the Verisign certificate named “SecureServer.509″ onto your hard drive - normally in /etc/cert/SecureServer.509
c) This file should have world readable permissions.
2) Now create a configuration file /etc/wpa_supplicant.conf as shown below:
—————
ctrl_interface=/var/run/wpa_supplicant
network={
ssid=”tigernet2″
scan_ssid=1
key_mgmt=WPA-EAP
eap=PEAP
identity=”CC-USERNAME”
password=”CC-PASSWORD”
ca_cert=”(Where you cert file that you downloaded in step 1 is, normally /etc/cert/SecureServer.509)”
phase1=”peaplabel=0″
phase2=”auth=MSCHAPV2″
}
—————
3) Now that the conf file is made, run the wpa_supplicant command as follows:
# wpa_supplicant -iwlan0 -Dwext -c /etc/wpa_supplicant.conf
(Note that you can add a “-dd” switch to the end for diagnostic information if you need to troubleshoot)
(Also note that you should replace “iwlan0″ with whichever designation your wireless card uses)
4) Run the dhclient command to renew your IP address:
# dhclient wlan0
5) Open a web browser and it should take you directly to the CC registration page. If this doesn’t work, try entering the address manually: http://computerregistration.coloradocollege.edu
6) Follow the onscreen instructions, including downloading the CSA agent (CSA.sh)
7) Run the CSA agent (./CSA.sh)
8) After it’s finished, run the dhclient command one more time and that should be it!
# dhclient wlan0
Non-Ubuntu, Using Network Manager
2) The key to connecting with NetworkManager is starting the daemon. Fedora Core 6 comes with it preinstalled so a quick start command should do the trick. (In Ubuntu, use sysv-rc to start the service).
Service networkmanager start
In Fedora, the NetworkManager frontend automatically starts with the daemon and places itself in the Gnome taskbar usually next to the time.
3) Click on the icon and a list of wireless networks will appear. Click on “tigernet2″ and you will be prompted with the following screen:
4) NetworkManager should recongize that the network is WPA Enterprise, the EAP Method is PEAP, the Key Type is Automatic. Your Identity is your CC Username, your Password is your CC Password, and the CA Certificate File is the certificate you downloaded earlier.
After you input the information, click Login to Network and you should be connected! Do not worry if it takes a few seconds
5) Run the dhclient command to renew your IP address:
# dhclient wlan0
6) Open a web browser and it should take you directly to the CC registration page. If this doesn’t work, try entering the address manually: http://computerregistration.coloradocollege.edu
7) Follow the onscreen instructions, including downloading the CSA agent (CSA.sh)
8) Run the CSA agent (./CSA.sh)
9) After it’s finished, run the dhclient command one more time and that should be it!
# dhclient wlan0
