Detailed instructions in case of problems

Step 1: installation of the required SW

At the beginning, check if your distribution includes Network Manager and WPA supplicant. Since most distributions already include these programmes, it shouldn’t be a problem.

In case you do not have them, you need to install them additionally. If you do not wish to install them, go to step 3.

Of course, it is necessary to have a functioning wireless network card.

Step 2: individual setting of network connection using Network Manageru

Click at the icon for network connections

and select eduroam network.

A configuration dialogue will be displayed; set it according to the image below:

Do not forget about username in the form UČO@muni.cz and your secondary password.

Then the certificate is important. We use the certificate signed as AddTrust External Root. In case you do not have it in /etc/ssl/certs/, download it here. Set it as a CA certificate file. Set the other items as follows:

  • Authentication: Protected EAP (PEAP)
  • Anonymous identity: leave blank
  • Version of PEAP: Automatically
  • Internal authentication: MSCHAPv2

Then click at Connect. In case all data entered are correct, you will be connected in a while.

Step 3: manual configuration

If your connection functions using the Network Manager, you do not need this step! Download this package, login as system admin (root) and unfold it in /etc/wpa_supplicant/. Two files will appear in this directory: eduroam and CA_cert.pem. Open the eduroam file in your favourite text editor and write your UČO and secondary password:

# IEEE 802.1X with dynamic WEP keys using EAP-PEAP/MSCHAPv2    
ctrl_interface=/var/run/wpa_supplicant    
network={    
          ssid="eduroam"    
          key_mgmt=WPA-EAP    
          eap=PEAP    
          phase1="peaplabel=0"    
          phase2="auth=MSCHAPV2"    
          identity="UCO@muni.cz"    
          password="SECONDARY PASSWORD"    
          ca_cert="/etc/wpa_supplicant/CA_cert.pem"    
}

Using the eduroam network is not controlled by a firewall in any way. Hence, it is very important to secure your computer with your own firewall.
