[править] Uatoken в Linux и Windows

В данной статье описан пример настройки аутентификации пользователей, подключающихся к vpn-серверу под управлением ОС Debian GNU/Linux, с использованием сертификатов. В качестве туннельного протокола - L2TP с использованием PreShared Keys. Сертификат пользователя, его закрытый ключ, должны находиться всегда на usb-устройстве uatoken. В качестве такого устройства может использоваться как устройство с маркировкой uatoken, так и uatoken S (только последнее может быть использовано в unix ос). В качестве клиента используется компьютер, под управлением OC Windows XP SP3.

Так как в данной статье используется устройство uatoken, то использование более простого способа с помощью OpenVPN не достаточно. Это связано с тем, что клиент OpenVNP не способен с использованием ПО производителя обратиться к usb-устройству: 

C:\Program Files\OpenVPN\bin>openvpn.exe --show-pkcs11-ids "c:\Program Files\uaToken\Drivers\utpkcs11.dll"

The following objects are available for use.
Each object shown below may be used as parameter to
--pkcs11-id option please remember to use single quote mark.

При использовании другого свободно распространяемого программного обеспечения результат тот же: 

C:\Program Files\OpenVPN\bin>openvpn.exe --show-pkcs11-ids "C:\WINDOWS\system32\opensc-pkcs11.dll"

The following objects are available for use.
Each object shown below may be used as parameter to
--pkcs11-id option please remember to use single quote mark.

В то же время стандартный vpn-клиент windows способен получить доступ к usb-устройству. Следовательно необходимо настроить серверную часть, под управлением ОС Debian GNU/Linux, так чтобы стандартный vpn-клиент windows мог установить vpn-соединение поверх туннельного протокола L2TP с использованием Preshared Keys и аутентифицировать пользователя по сертификату с его usb-брелка. Ниже пойдет речь именно об этом

[править] Настройка pppd

Прежде чем настраивать демон pppd необходимо его скомпилировать с поддержкой EAP для проверки подлинности сертификата, предъявляемого клиентов при соединении для аутентификации.

  • Установка необходимого ПО: 
apt-get install libcurl4-openssl-dev
  • Сборка pppd 
wget -c ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz

tar xvzf ppp-2.4.4.tar.gz

cd ppp-2.4.4/

patch -p1 < ../ppp-2.4.4-eaptls-mppe-0.94.patch

./configure

make

make install
