I would like to monitor data from the specific IP address and port and at the same time, save those data into file. But this does not look like regular socket programming because my program should re-send data to the place the data was supposed to go after my program saves it.
I don't know where to start.

			

			ex) PC 1 : application port 6000
			

			

			PC 2 : application port 6001
			

			

			PC 1 sends data to PC2. I would like to run my program on PC 2.
