For configure the conexion under a Linux environment (in this tutorial, under Ubuntu 10.04) we need to have insalled Network Manager (installed by default in all Ubuntu distros) and follow a simple steps:
1. From the top menu bar select the networks icon.
2. From the menu that appears select UPVNET.
3. Complete the Wireless Network Authentication Required dialogue box as shown below.
Wireless security: use WPA & WPA2 enterprise
Authentication: use Protected EAP (PEAP)
Anonymous identity: empty
CA certificate: use Thawte_Premium_Server_CA.pem . Click on the CA Certificate widget to open a file browser window Click File System in the Places column ->Double-click on etc in the right hand column ->Scroll down and double-click on ssl in the right hand column ->Double-click on certs in the right hand column ->Double-click on Thawte_Premium_Server_CA.pem
If you use KNetworkManager of KDE, you must convert the PEM certificate to a DER certificate with following commands:
$ mkdir ~/ca-cert
$ openssl x509 -inform PEM -in /etc/ssl/certs/Thawte_Premium_Server_CA.pem -outform DER –out ~/ca-cert/Thawte_Premium_Server_CA.der
Then, use the newly created cert-file, ~/ca-cert/Thawte_Premium_Server_CA.der, as the CA Certificate in knetworkmanager. (You might have to reboot as well.)
Inner authentication: use MSCHAPv2
Use your credentials with next sintaxis

4. Select Connect
Your computer will now be authenticated to the network, after that you should be able to access the internet. If you get an error saying that authentication has failed, double-check the above steps. If you are still unable to connect, then contact the Help Desk for assistance. All the settings you have made are stored in your computer and should not need re-entering each time you connect to the UPVNET network.
