Tcp Tutorial-16

Due to this FAKE and REAL IP reasons, when a person is trying to perform an IP Spoof, he does not get any response from the remote host and has no clue whether he has been successful or not. If he has made any progress or not. You are as good as blind, with no medium through which you could get feedback.

IP Spoofing can be successful only if the computer with the FAKE IP does not reply to the victim and not interrupt the spoofed connection. Take the example of a telephone conversation, you can call up a person ' x ' and pretend to be ' y ' as long as ' y ' does not interrupt the conversation and give the game away.

So why would you need to perform IP Spoofing-:

1.) To Pretend that you are some other computer whose IP address is amongst the trusted list of computers on the victim's disk. This way you are exploit the 'r' services and gain access to the network as you are then believed to be from a trusted source. 2.) To Disguise or Mask your IP address so that the victim does not know who you really are and where the data is coming from.

If you ever read the alt.2600 or the alt.hacking newsgroup, you would probably find many postings like "I have Win98, how do I Spoof my IP" or even " I do not know TCP/IP. tell me how to perform IP spoofing". You see the very fact that they are posting such questions and expect to learn how to spoof their IP without even knowing a bit about TCP\IP, confirms the fact that they would not be able to perform IP Spoofing. No I am not saying that asking questions is bad, but you see not knowing something is not so bad, but not knowing something and showing ignorance towards learning it is really, really bad.
