intercept packets and add 50 bytes to packets to the payload

OS: Linux Programming language: C/C++/java/python Delivery: 4 days Project description: Develop a program, which runs on a host and keeps monitoring all packets sent to the host. For each packet, add 50 bytes to the payload. For example, the original packet size is 1000byte, after processed by the program the packet size is 1000+50 = 1050 bytes. For the content of the 50 bytes, we need to include the host's src/dst MAC and IP addresses, and add other random numbers to 50 bytes. Then the program send the processed packets back to their incoming port. Please make sure that don't change the original source/dst mac and ip address.
