@ 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
