Last active July 3, 2019 09:59

A dummy client through which you can send and receive data. Built using socket programming in Python 3.5.

	import socket

	IP_ADDR = "127.0.0.1"
	SOCKET_PORT = 5000

	with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as skt:
	skt.connect((IP_ADDR, SOCKET_PORT))
	while True:
	usr_ch = input("Send or receive [s/r]? (0 to exit): ")
	if usr_ch == 's':

TheProjectsGuy / dummy_server.py

Last active July 3, 2019 09:59

A dummy socket that acts as a server through which you can send and receive data. Built using socket programming in Python 3.5.

	import socket

	IP_ADDR = "127.0.0.1"
	SOCKET_PORT = 5000

	with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as skt:
	skt.bind((IP_ADDR, SOCKET_PORT))

TheProjectsGuy / SocketClientSpeaker.py

Created July 1, 2019 12:18

A simple socket client that will connect to a server, send "Hello World" and then end connection and terminate.

	import socket

	# IP address and port of connection
	IP_ADDR = "127.0.0.1"
	PORT = 50001

	with socket.socket(
	socket.AF_INET, socket.SOCK_STREAM
	) as skt:
	# Connect to the IP_ADDR and PORT (server address)

TheProjectsGuy / SocketServerListener.py

Created July 1, 2019 12:11

A listener node which is a server. It simply connects, receives a message, prints it out, ends.

	import socket

	# An IP address for communication
	IP_ADDR = "127.0.0.1" # Internal loop back
	# Port to connect to
	PORT_NO = 50001

	with socket.socket(
	socket.AF_INET, socket.SOCK_STREAM
