Хорошо, вот что выходит с netcfg.
1.Создал профайл corbina:
CONNECTION='ethernet'
DESCRIPTION='A basic dhcp ethernet connection using iproute'
INTERFACE='eth0'
IP='dhcp'
## for DHCPv6
#IP6='dhcp'
## for IPv6 autoconfiguration
#IP6='stateless' 
2. Прописал его в rc.conf, закомментив строки от network даемона, заодно добавил ту волшебную строчку, которая давала возможность хотя бы достучаться до корбиновского л2тп сервера:
NETWORKS=(corbina)
POST_UP="ip route add 85.21.0.251 via 10.163.88.1 dev eth0 metric 202" 
3. Запустил netcfg corbina.
4. Запустил x2ltpd даемон с этим конфигом:
[global]
access control = yes
[lac corbina]
lns = 85.21.0.251
redial = yes
redial timeout = 1
require chap = yes
require authentication = no
name = 0893304887
ppp debug = yes
pppoptfile = /etc/ppp/options.xl2tpd
require pap = no
autodial = yes
tx bps = 100000000 

После всего этого вот что имеем.

virus_found, предлагаешь и нам ещё месяц терпеть твою печаль?
Выкладывай сюда все конфиги которые участвуют в твоём подключении. Все!

ps. Мог-бы и сам давно уже об этом догадаться. Я говорю о конфигах. И как следствие отсутствия оных - о дружественной модерации.
Не думаю, что я какой-то конфиг пропустил. Вот они все:

Попробуйте в конфиг pppd добавить noproxyarp ?
Ок, спасибо. Убралось назойливое сообщение из лога :)

Скажите, а в скрипте /etc/ppp/ip-up у Вас что-нибудь есть? А то в логах пишет, что запускается и отрабатывает, а потом на ~30 сек. все замолкает и дисконнект. Нет там ничего “криминального”?
Не менял его, штатный он от ppp 2.4.5-2:
#!/bin/sh
#
# This script is run by pppd when there's a successful ppp connection.
#
# Execute all scripts in /etc/ppp/ip-up.d/
for ipup in /etc/ppp/ip-up.d/*.sh; do
  if [ -x $ipup ]; then
    # Parameters: interface-name tty-device speed local-IP-address remote-IP-address ipparam
    $ipup "[email protected]"

done

Эх, печаль, уже с месяц всё это терплю. На этой же машине в вин хр - всё с одного клика :(

Вам надо сервер L2TP (85.21.0.248) прописать в постоянный маршрут, чтобы оно ходило через eth0. DHCP у Вас работает нормально.

Специально “задизейблил” network, для наглядности. И собственно, соединением будет рулить уже т.н. net-profile. Это если используется netcfg (а как без него нынче?), ну и xl2tpd туда-же, вслед за “профилем”, если настраивается посредством его.
Я с этими netcfg-ами не сталкивался напрямую, корбиной давно уже не пользуюсь, но вцелом, как-то так.
А подробнее насчёт netcfg и net-profile вики почитайте, она поможет=)
Почитал.
For systems connecting to a single network, the network daemon may be more appropriate.
Начисто netcfg не нужен.

Ну а в логах даемонов - network unreachable, как и всегда. Думаю, к новому году сделаю? Ещё эта дружественная модерация на форуме скорости не прибавляет.
interface=eth0
address=
netmask=
broadcast=
gateway=10.123.160.1
Логи не изменились. Network unreachable. Что-то dhcp у меня совсем не то делает. Кто-нибудь может показать rc.conf рабочий сейчас? И нужны ли bind и pptp?
vadik
Вы наверное давно обновлялись. Формат описание сетевых настроек в файле rc.conf давно уже поменялся. Почитайте подробнее тут.
Меньше месяца назад. А что именно у меня в rc.conf неправильно?
Недолго была радость на онлайме, где нужно было только поднимать eth0, теперь придётся давиться корбиной.
Пробема очевидная - интернета нет :) Потратил три часа для разгадывания этой убийственной головоломки - тщетно. То network unreachable, то unknown host. Подозреваю, что смотреть надо в сторону rc.conf.
