ADSL-en PPP link rejtelyes modon meghal

Linux-haladó

Sziasztok!

Adott:

- friss Gentoo linux ADSL routerkent
- PPP-ben LCP EchoReq mindket oldalon bekapcsolva

A jelenseg:

Nehany nap utan, amikor epp nincs forgalom a vonalon, nem jon valasz a routerrol kuldott EchoReq-re, tehat a link meghalt. Ezzel nem lenne semmi gond, de a sikeres ujracsatlakozas utan rogton fellep a problema ismet es kizarolag az oldja meg, ha ujrainditjuk a gepet.

...es ez megy, amig ujra nem inditjuk a gepet. PPP stop/start sem segit.
Otletek?
Valami hardver hibara gyanakszunk, de nem tiszta, hogy hol kene kezdeni a vizsgalodast.

Néhány random ötlet:

Próbáltátok már másik hálókártyával?
Szolgáltató ránézett már?
Auto-neg helyett fixen beállítani a csatlakozást? (pl. 100Mbit full-duplex auto neg off)

( George.Roman | 2009. 09. 17., cs – 18:15 )

Egyértelműen hardver... volt egy esetem szervizesként:

ADSL PPPoE DCHP autoneg... --> kapcsolatban --> inaktív állapotban leszakad --> redial --> eredmény: zéró (gép újraindít, rendszer ismét, modem restart).
Csak ez utóbbi segít.
Szolgáltató/DSL vonali mérések/kábelek/splitter/anyázás/... minden megvolt... modemcsere lett belőle, és azóta panaszmentes.

( George.Roman | 2009. 09. 18., p – 14:17 )

Valószerűtlen, de érdemes megvizsgálni:

- Splitter
- ADSL kábel csalakozói
- Egyéb, a splitter utáni teflon(ok) lehúzása a kábelről.

Vonali zajnak tűnik a dolog első ránézésre.

Másik metódus:
Aktív a keepalive? Lehet, h a másik oldal nem veszi jó néven az ébrenléti üzeneteket. Ha állandóan inaktív állapotra való áttéréskor jelenik meg az esemény, akkor ez is lehet egy hiba.
