Linux + dial-up + siol

In navaden (ne TA) isdn adapter... obstaja kdo ki ima to kombinacijo?

Ker imam dolocene probleme, da me mece dol (vsake tolk casa) brez resnega razloga.

Sem malo debugal... in nasel odgovore na mnoga vprasanja...

Recimo.. pojavljanje spikov pinga... (ki so odurno moteci pri spilanju online iger)

Stvar je taka.. to se pojavlja ne glede na isdn adapter, in ne glede na OS...

Paket je dolg tocno 1500 bytov kolikor je MRU (max receive unit)
In windowsi ga morda razumejo.. oz. ga ignorirajo.

Linuxov ipppd ga pa ne razume in tudi poslje nazaj siolu, da pac tega protokola ne pozna, da je utegnilo priti do napake.
Siol nas paket ignorira, ga ima za napako...
ce se pojavi doloceno stevilo takih paketov na dolocen cas.. (mislim da je 10 na minuto) nam siol prekine IPCP (IP control protocol za ppp) in nasa povezava "umre". Razlog za to pa je t.i. "bad line quality".

Sedaj sem hacknil ipppd, da "unknown protocol" messagov ne posilja vec siolu nazaj in so far so good...
