Ciao,
...uso una connessione ISDN a Tiscali, e monitorando ippp0 con tcpdump, vedo
che mi arriva un sacco di roba appena stabilisco la connessione, e anche se
non c'è alcun traffico in uscita!!!
Il problema è che "vedendo" traffico il modulo isdn non mi sgancia in
automatico la linea.
Cossa posso fare per eliminare tutto questo traffico? (che tra l'altro sono
"boadcast",giusto?)
Ciao e grazie.
...questo è un esempio:
