День добрый. В *nix я разбираюсь слабо, но пытаюсь собрать небольшой офисный шлюз из opensuse 11.3 + freeradius 2 + abills 0.50 + pppoe (pppd). Устанавливалось всё по инструкции с сайта. Заработать заработало, но не выдавались адреса из пула.
Начал копать, копал долго. Пришёл к выводу, что по какой-то причине radiusd игнорирует атрибуты, возвращаемые exec-program-wait.
Привожу лог для искусственно сконструированной ситуации: создал в /etc/raddb/users специально пользователя, аналогичного пользователю внутри abills (раскомментил пример с кучкой атрибутов). Из лога видно, что в Sending Access-Accept атрибуты из users попадают, а те, что, как вроде бы видно, прекрасно выданы exec-program-wait - уходят в никуда. Соответственно, если бы я пользователя не создавал, ответный пакет был бы вообще чистый, только с Access-Accept и всё.
Помогите, где может быть косяк?Лог Radiusd -X

Мораль - прописывайте все левые атрибуты в словарь. Радиус пугается выброса скрипта, в котором есть неизвестный ему атрибут.
Поведение, на мой вкус, мягко говоря, сомнительное :(
