はじめに†

802.1xはport単位で接続の認証を行うプロトコル

↑

用語・略語†

RADIUS
Remote Authentication Dial-In User Service
EAP
Extensible Authentication Protocol
PAE
Port Access Entity
CCMP
Counter with CBC-MAC Protocol
↑

XSupplicant†

Debian

# apt-get install xsupplicant

/etc/xsupplicant/xsupplicant.confで

deny_interfaces = eth0

して

/etc/init.d/xsupplicant restart

しないと一切リモートアクセスできません:-)

ちなみにWPA Supplicantも同様の機能をもっているので上の作業は無駄です。

# apt-get remove xsupplicant

WPA EAP-TLS on WN-AG/CB2†

/etc/wpa_supplicant.conf

network={
   ssid="tacoma"
   key_mgmt=WPA-EAP
   eap=TLS
   identity="hasebe"
   ca_cert="/etc/cert/cacert.pem"

WPA EAP-TLS on WN-AG/CB2 (Windows)†

  1. Certificate Autority関係を何とかする。
  2. /usr/local/etc/raddb以下の環境ファイル（死ぬほどある）を何とかする。
  3. APの設定を何とかする。
  4. 証明書などをクライアントマシンにコピーして何とかする。
