Здравствуйте All,

Скажем сутанавливается соединение с удаленной машины (Win XP) на
dial-in сервер (ALM2) далее пробуем:
ping адрес_сервера, проходит на ура... тут же пробуем еще раз... 100%
потерь... как так?
Причем ситуация со 100% вероятностью повторяется...

[root@bug root]# ifconfig ppp0

Тут я решал сам удаленную сторону пропингать на этом все и поломалось!

Не прокатил!

Вопрос до кучи что значить:
Jan 25 16:43:34 bug kernel: device ppp0 entered promiscuous mode
Jan 25 16:46:40 bug kernel: device ppp0 left promiscuous mode
???
