Claim:
1. A method for identifying a source and a reason of a reset in a Transmission Control Protocol (TCP) session, the method comprising: preparing, at an application executing in a target data processing system, a reset packet for the TCP session; adding, by the application at the target data processing system, using a first header in the reset packet, an identifier associated with the target data processing system, wherein the identifier associated with the target data processing system is unknown to a sender data processing system of a data packet in the TCP session, and wherein the TCP session is established between the sender data processing system and a receiver data processing system, wherein the target data processing system is not a part of the TCP session, and the sender sends the data packet to the receiver data processing system during the TCP session; adding, responsive to the data packet reaching the target data processing system instead of the receiver data processing system, by the application at the target data processing system, using a second header in the reset packet, a reason for resetting the TCP session; and resetting, by the application at the target data processing system, the TCP session by sending the reset packet from the target data processing system to the sender data processing system.
