Długi czas nawiązywania połączenia

[mistrz1]

Rano połączenie jest nawiązywane szybko, tak samo wznawianie połączenia, wszystko w parę sekund. Wieczorem, tak jak teraz, jest kłopot, bo trwa to kilkadziesiąt sekund albo parę minut. Zastanawiam się, czy w obecnej sytuacji brakuje adresów IP w aero2? Jakoś nie zauważyłem, żeby doszła nowa pula adresów, ani Jakub nic o tym nie wspomina. A jak widać użytkowników jest coraz więcej. Czy obecna ilość adresów IP jest wystarczająca?

[grzech1991]

Ale pula adresów IP dla aero2 jest osobna, niż dla plusa. Przynajmniej tak mi się wydaje.

Objaw który masz, również może wskazywać na obciążenie sieci.

Co znaczy obciążenie sieci?

[jakubd]

Sieć operatora w tej lokalizacji jest przeciążona.

[gandi21]

Problem jest w protokole IPCP, w części odpowiadającej za przydzielenie adresu ip końcówce - wygląda na to, że tych wolnych adresów już nie ma lub serwer ma kłopoty z poprawnym ich przydzielaniem.

Ustaw w /etc/ppp/options:

192.168.1.1:10.64.64.64
logfile /dev/null
nocrtscts
lock
maxfail 0
lcp-echo-failure 4
lcp-echo-interval 65535
noipdefault
noauth
refuse-chap
refuse-mschap
refuse-mschap-v2
mru 1500
asyncmap 0
defaultroute
ipcp-max-failure 1000
ipcp-accept-local
persist
holdoff 1

Dzięki temu będzie próbował pobrać adres więcej razy - 1000, a czas opóźnienia między próbami ponownego połączenia po jego zakończeniu wyniesie tylko 1 sekunde - zamiast 30 domyślnie.

Nie rozwiąże to problemu całkowicie ale powinno zmniejszyć czas oczekiwania na połączenie.
