Здравствуйте!

Есть такая проблема. Система Debian Linux Sarge, подключился по локальной сети к местному провайдеру. Интернет он раздает по VPN, но настроить соединение под Linux не удалось.
Вот конфиги:

/etc/ppp/options.pptp

noauth
refuse-chap
debug

/etc/ppp/chap-secrets

<login> PPTP <passwd> *

/etc/ppp/peers/altair

pty "/usr/sbin/pptp vpn.altair-tv.net --nolaunchpppd"
connect /bin/true
name <login>
remotename PPTP
file /etc/ppp/options.pptp
ipparam altair

/etc/ppp/ip-up.d/altair

route del default
route add default dev ppp0

При попытке подключения (pon altair или pppd call altair) соединение не устанавливается, в логах имеем следующее:

Собственно и всё, процессы в памяти не остаются и соединения нет...
Подскажите, куда копать?
