OSError: [WinError 10013] An attempt was made to access the socket in a way that is not permitted by the access permissions.
It seems to be the problem caused by "sender = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW)", but the reason is not clear

With the parameter --quiet (short -q) no sent or received messages are shown but only the start message and the summary.

measure round trip time of package
add the timings to the statistics (min, max, average)

The server is stopped via CTRL-C, which leads to a stack trace message.
A proper shutdown of the server with a nice output should be implemented.

Currently the message is created randomly.
It should be possible to define a message that will be sent instead of the random message (like ping on linux systems).

Add a statistic calculation and output as the ping tool does it (n packets transmitted, m received, x% loss)

use standard udp socket to send data - some features have to be disabled
