Create certificates

You need to create/use a certificate to connect to the WPA2 access point.

1. Connect to the unencrypted wireless network metalab_802.11g_WPA2-certcreate
2. Open your browser and go to https://10.215.23.1/
   Please verify the fingerprints to make sure that there is no man in the middle pretending to be webserver:
   SHA1 E1:C4:0F:06:C9:0A:C0:71:D3:D5:75:73:C7:D8:ED:FD:E7:40:15:05
   MD5 24:28:1F:FF:4F:E5:EA:47:A0:3A:FD:D4:0D:A0:8B:62
   For the even more paranoid people: you should also check the history of this page to verify that noone altered the checksums.
3. Create the certificate by entering a hostname and password

You are now able to connect to the network by using the ca and your client certificate.

Use certificates

Linux

wpa_supplicant

sample wpa_supplicant.conf:

 network={
   ssid="metalab-wpa2"
   scan_ssid=1
   key_mgmt=WPA-EAP
   proto=WPA2
   eap=TLS
   pairwise=CCMP
   group=CCMP
   identity="yourname"
   ca_cert="/path/to/ca.crt"
   client_cert="/path/to/yourname-cert.pem"
   private_key="/path/to/yourname-key.pem"
   private_key_passwd="secretpassword"
 }

NetworkManager 0.6

Use yourname as identity, ca.crt as ca-certificate, yourname-cert.pem as client-certificate and secretpassword as key-password.

NetworkManager 0.7

Use yourname as identity, leave the client-certificate untouched, ca.crt as ca-certificate, yourname-cert.p12 as key (this includes the client cert) and secretpassword as key-password.

MacOS X

Import the ca-certifcate "ca.crt" to the system keychain.

Set the trust level for the ca-certificate

Import the client certifcate "yourname-cert.p12" to the login keychain with the choosen import password.

Connect to the metalab-wpa2 network
(No Login, No Password, change the used certificate to the one you added to your Login keychain.)

Windows

Windows XP (SP3)

• deine ...-cert.p12 doppelklicken, dem assistenten folgen (passwort wird gebraucht)
• ca.crt doppelklicke, dem assistenten folgen

eventuell, falls das nicht reicht um eine verbindung aufzubauen:

1. Start -> Einstellungen -> Netzwerverbindungen -> doppelklick Drahtlose Netzwerkverbindung oder in der taskleiste auf das WLAN symbol
2. "Eigenschaften"
3. Reiter "Drahtlosnetzwerke"
4. Metalab ..._WPA2 auswählen
5. "Eigenschaften"
6. Reiter "Authentifizierung"
7. EAP-Typ: "geschütztes EAP (PEAP)"
8. "Eigenschaften"
9. Autthentifizierungsmethode auswählen: "Smartcard oder anders Zertifikat"

Manual server side setup

Create a certificate

 ## connect to wpa-01.in.metalab.at (10.20.30.25) as root.
 # user@host:~# ssh -l root wpa-01.in.metalab.at
 # root@wpa-01:~# ./mkclient.sh hostname password
 # root@wpa-01:~# exit
 ## copy the certificates to your host
 # user@host:~# scp -r root@wpa-01.in.metalab.at:/tmp/yourname.tar /path/to

Revoke certificate

 ## connect to wpa-01.in.metalab.at (10.20.30.25) as root.
 # user@host:~# ssh -l root wpa-01.in.metalab.at
 # root@wpa-01:~# cd /ca
 # root@wpa-01:~# ./revoke.sh yourname
 ## enter ca password
