python rawsocket tools

Fiddle with rawsocket in python3, implementing some commonly used network troubleshooting tools. All the scripts need superuser privilege to run. The traceroute and mtr scripts are not applicable to Windows, because I do not know and am not interested in how to modify IP header with python raw socket on Windows.

ping

$ python3 pyping.py -h
usage: pyping.py [-h] [-d DATA | -s SIZE] [-i INTERVAL] [-w TIMEOUT]
                 [-c COUNT] [-t TTL] [-I INTERFACE] [-q] [-v]
                 target

  -p PORT, --port PORT  set the destination port to test; only apply to TCP
                        and UDP traceroute; defalut to use various port;
  -v, --verbose         show verbose per hop RTT output
  -I, --icmp            use ICMP echo request to traceroute; the default
                        option, could be omitted
  -U, --udp             use UDP to traceroute
