WLAN

We're moving our wifi infrastructure to an authenticated and encrypted ssid. At the moment it's hard to change our internal wifi password, because our door system depends on it. If you are not in our internal wifi you can't operate the door.

This is one reason why we want to use 802.1x with EAP-TTLS. Every member has it's own username/password combination which can be reset or changed through a webinterface. If a member quits the space, we just have to deactivate the account and the internal access is gone.

The other reason is: Every member has its own encrypted channel to our access points. In addition the member has the possibility to check, if the SSID can be trusted (avoid roque APs) with an ssl certificate

certificate

To check if you're connecting to the correct SSID, you can and should add the ssl certificate to your connection setting. You can download the SSL Certificate from our Server.

Warning: The certificate expires every two years. You can also check against the StartSSL G2 certificate which is valid much longer.

netctl

Save config as /etc/netctl/$interfacename-backspace_8021x. You have to restart netctl-auto (e.g. systemctl restart netctl-auto@$interface)

Description='backspace WPA2 802.1X'
Interface=wlp3s0s
Connection=wireless
Security=wpa-configsection
IP=dhcp
ESSID="backspace 802.1x"
WPAConfigSection=(
    'ssid="backspace 802.1x"'
    'proto=RSN WPA'
    'key_mgmt=WPA-EAP'
    'eap=TTLS'
    'identity="USERNAME"'
    'password="YOUR_PASSWORD"'
    'phase2="auth=PAP"'
)

You can enable SSL certificate checking with 'ca_cert="/path/to/your/hackerspace-bamberg.de.crt"'. For the certificate look at Technische_Infrastruktur/WLAN#Certificate.

wpa_supplicant

Add to /etc/wpa_supplicant/wpa_supplicant.conf:

network={
 ssid="backspace 802.1x"
 key_mgmt=WPA-EAP
 eap=TTLS
 identity="USERNAME"
 password="YOUR_PASSWORD"
 phase2="auth=PAP"
}

You can enable SSL certificate checking with ca_cert="/path/to/your/hackerspace-bamberg.de.crt". For the certificate look at Technische_Infrastruktur/WLAN#Certificate.

Linux - NetworkManager

Ignore the certificate warning as long as we don't provide a certificate.

Windows 7

Windows 7 does not support EAP-TTLS / PAP from scratch. The same is true for eduroam networks and this is why there are a lot of instructions from universities which use SecureW2 as an additional Software to enable EAP-TTLS:

• https://www.cms.hu-berlin.de/de/dl/netze/wlan/config/eduroam/win7/eduroam-win7-securew2.pdf

TODO: Own instructions and screenshots

Windows 8 and above

Since Windows 8 the system itself is capable of EAP-TTLS.

TODO: Someone with windows should do some screenshots.
