ppp: po pripojeni nefunguje prenos

[Petr Honsa]

dobry den,

mam problem s internetovym pripojenim pres modem, ktery bez problemu funguje
napr. v Knoppixu (dokonce s uplne stejnym hardware). cely prubeh
pripojovani vypada uspesne, nicmene spojeni nefunguje.

wvdialem vytocim cislo a otevru PPP spojeni :

[root na blueFiSH etc]# wvdial
--> WvDial: Internet dialer version 1.41
--> Initializing modem.
--> Sending: ATZ
AT[7f]Z
OK
--> Modem initialized.
--> Sending: ATX3DT 971101010
--> Waiting for carrier.
AT[7f]X3DT 971101010
CONNECT 115200
--> Carrier detected.  Starting PPP immediately.
--> Starting pppd at Sat Nov 15 13:16:51 2003

PPP spojeni se navaze, nastavi se IP adresy a DNS servery :

spravne se nastavi i defaultni brana do internetu :

[root na blueFiSH root]# route -n

ping na jakoukoli IP adresu (modem providera, nebo jakoukoli internetovou
adresu) ale nefunguje (100% packets lost).

poradite nekdo, kde hledat problem, napr. chyba v pppd ?
