Student Resident "Erik" did the awesome work of tracking down Eduroam instructions for students running Linux. Thanks Erik! Erik writes:
Here are the settings that worked for me, as based on the MIT webpage http://kb.mit.edu/confluence/pages/viewpage.action?pageId=152599592 :
* Wireless security: WPA & WPA2 Enterprise
* Authentication: Protected EAP (PEAP)
* Anonymous identity: (leave blank)
* PEAP version: Automatic
* Inner Authentication: MSCHAPv2
* Username: [SUNet_ID]@stanford.edu
* Password: [SUNet password]
1. Find Network Manager, edit settings in "security" tab as above
2. Click on CA certificate. Navigate to /usr/share/ca-certificates/mozilla and select the file "AddTrust_External_Root.crt". Click Open. Alternatively, if this file is missing from your Firefox installation, you can always download AddTrust's public key file from their website (https://support.comodo.com/index.php?/Default/Knowledgebase/Article/View/917/91/) .
3. Returning to the Authentication required window, click Connect. If all goes well, you should be connected to the network.
NB: I'm not sure if step 2 with the CA certificate is actually required, since I initially checked the checkbox "No CA certificate is required" and it seemed to work. I then went back and added the certificate and it still worked.
Did this work for you (or even if it didn't)? Let us know in the comments below!
