error: ppp0: failed to set IPv4 address: Invalid argument

Post by shylion » 23 Jan 2019, 03:52

Приветствую, коллеги.

Сабж используется как pptp/l2tp сервер в маленькой организации, никаких продвинутых фич не используется, только совместимость с pppd.

Через некоторое время работы (недели), перестает форвардить траффик клиенту, при этом от клиента траффик приходит.

В логе при старте сессии такое:

Code: Select all

[2019-01-22 17:58:30]:  info: l2tp: new tunnel 31899-24250 created following reception of SCCRQ from 91.x.x.x:35642
[2019-01-22 17:58:30]:  info: l2tp tunnel 31899-24250 (91.x.x.x:35642): established at 185.y.y.y:1701
[2019-01-22 17:58:30]:  info: l2tp tunnel 31899-24250 (91.x.x.x:35642): new session 36347-18169 created following reception of ICRQ
[2019-01-22 17:58:33]:  info: ppp0: connect: ppp0 <--> l2tp(91.x.x.x:35642 session 31899-24250, 36347-18169)
[2019-01-22 17:58:33]:  info: ppp0: lion: authentication succeeded
[2019-01-22 17:58:33]: error: ppp0: failed to set IPv4 address: Invalid argument
[2019-01-22 17:58:33]:  info: ppp0: session started over l2tp session 31899-24250, 36347-18169
Лечится простым перезапуском службы.

Конфиг:

Доброго времени суток. Какая версия используется? покажите вывод команды

Code: Select all

accel-cmd -V
Accel не смог почему-то установить netmask, в master ветке подобную проблему исправляли.

Куда еще посмотреть, когда ситуация повторится?

ip addr show dev ppp0 ?

Скорее всего отключено в секции [cli] конфигурационного файла accel-ppp.conf
Попробуйте собрать из ветки мастер, вот документация https://accel-ppp.org/wiki/doku.php?id= ... ion_ubuntu
