You want to carry out session hijacking on a remote server. The server and the client are communicating via TCP after a successful TCP three way handshake. The server has just received packet #120 from the client. The client has a receive window of 200 and the server has a receive window of 250.
Within what range of sequence numbers should a packet, sent by the client fall in order to be accepted by the server?
A . 200-250
B . 121-371
C . 120-321
D . 121-231
E . 120-370
Answer: B
Explanation:
Package number 120 have already been received by the server and the window is 250 packets, so any package number from 121 (next in sequence) to 371 (121+250).
