capturing

hi gang ,
by the way i'm newby here ;)

a problem :
we are about to write a caputring program using raw sockets .
this program targeted to place over ppp wires. but our problem is that we try to capture LCP/ authentication/ NCP packets where tools like windump does'nt work before the network driver initialize tcp ip protocol stack .

give us a clue plz;

to enlighten the problem try to capture syncronization packets using winpcap powered tools like WINDUMP .
u recive nothing during sync time when LCP then authentication and Then NCP packets transmitted ....


thanks in advance.
