@ Chris :
I am using windows xp sp2.
@ Nobody :
My main aim here is decode the IP header.
I tried the below code and it seems to work.I have shifted to python
2.5 (though I think it was more of a code problem).My main problem is
to decode the IP header
s = socket(AF_INET,SOCK_RAW,IPPROTO_IP)
r = socket(AF_INET,SOCK_RAW,IPPROTO_IP)
r.bind(('',0))
s.connect(('localhost',0))
for i in range(10) :
s.send(str(i))
data = r.recvfrom(256)
hdr = r.getsockopt(SOL_IP, IP_OPTIONS, 20)
print binascii.hexlify(hdr)
r.close()
s.close()
Here it prints nothing.I'll try some more stuff and will post my
findings in about 30 minutes.
thanks
moijes
