Figure 7.4: Messages entered here will be sent unencrypted to the server.
Create a Threaded Server with TCP
You can expand on your socket knowledge by examining the next code listing.
The following script will create a server that you can send messages to via TCP.
This example, just like the previous communications, sends data unencrypted
from one application to another:
import socket
import sys
from _thread import *
host = 'localhost'
port = 5555
print (host, port)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
s.bind((host, port))
except socket.error as e:
print(str(e))
s.listen(5)
def threaded_client(conn):
conn.send(str.encode('Welcome, type your info\n'))
