Possible windows+python bug
This bug is produced on WindowsXP SP1 (OSVer : 5_1_2600) with Python2.3
installed.
Start Python and type (of course x.x.x.x should be replaced with IP address):
import socket
s=socket.socket(socket.AF_INET,socket.SOCK_RAW,4)
s.sendto("",("x.x.x.x",0))
Press ENTER and your win box should crash immediately.
On my test after restart windows returned BCCode : d1.
By the way, IP protocol 0x04 is "IP over IP", and I could send such datagrams
month ago with Python (although Microsoft has crippled some protocols).
Now, this is maybe specific to this configuration, or it could be due to some
driver (BCCode: d1 is specific for drivers related problems). It needs further
testing on different configurations.
