Because I work on a network emulator and I want to check biterros patterns so I need to access the data of the packets. An dsince my test program is written in Python, it's easier to do it in Python.

No, I want to do it on a machine with aliases as in:

ifconfig em0 10.0.1.1 netmask 255.255.255.0 alias
ifconfig em0 10.0.2.1 netmask 255.255.255.0 alias
ping -c4 -S 10.0.1.1 10.0.2.1


But I think I've found the solution: my_socket.bind((src_addr, 1))
