Доброго времени суток! Есть VPN-сервер, от которого есть логин, пасс и адрес. Методом подключения с windows-машины выяснил что поддерживается chap и mschap-v2 авторизация. С windows-машины подключается идеально.
С соседней linux-машины никак не выходит наладить _СТАБИЛЬНОЕ_ подключение. С никсов подключается один-два раза из сотни. Если подключилось - всё работает хорошо. Как только отключился - снова можно пол-дни долбиться для подключения.
Куда копать?
