Executing client and server

First, we start server execution with the echo_server_ipv6.py Python script. After executing this script, the server it will wait for connections:

usage: echo_server_ipv6.py [-h] --port PORT

When executing the server script, we must use the port argument to establish the number where the server is listening for connections:

python echo_server_ipv6.py --port 7575 Waiting connections in ::1:7575

python echo_client_ipv6.py --port 7575 Connected to the server --->::1:7575 Send data to server: Hello from ipv6 client Write your message >
