We are facing problems in sending and receiving
data on raw socket. We can't receive data through raw sockets on win 2k
Advanced Servermachine's (We found it documented on MS site.
http://support.microsoft.com/?kbid=890856 We could not obtain a update for
it.). We also can't send data through raw socket with header included option
'on' on win xp machines having service pack2.
Weird problem is, we can send data through raw sockets with header included
option
'on' on win xp machines having service pack 1, but we can't receive data
through raw sockets.
Also sending data through raw sockets with header included option 'on' is
possible on win 2k machines. We are able to send data if header included
option is switched 'off' on win xp sp2 machines. But it adds an extra ip+udp
header. Need to find other socket options to be set
along with header included option.
Actually we want to spoof address for purpose of developing simulators. We
want to keep the implementation simple. hence we are making use of raw socket
Which OS do we try on?
How much problems do we run into? It is good that microsoft tries to make
the lifes of hacker miserable, but a hacker anyways would not use a raw
socket when he can try more exploits with other stuff. Just this makes our
lives worst!!
We now have to use winpcap may be?
Could anybody give a definitive answer on this? Which OS should we work on?
