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
  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

Use yourname as identity, ca.crt as ca-certificate, yourname-cert.pem as client-certificate (with NetworkManager-0.7 you may need to use yourname-cert.p12 instead) and secretpassword as key-password.

MacOS X

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
