import socket
import sys
HOST, PORT = "192.168.1.40", 3360
data='Hello'
#data = data.join(sys.argv[1:])
# Create a socket (SOCK_STREAM means a TCP socket)
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
# Connect to server and send data
sock.connect((HOST, PORT))
sock.sendall(data + "\n")
# Receive data from the server and shut down
received = sock.recv(1024)
finally:
sock.close()
print "Sent: {}".format(data)
print "Received: {}".format(received)
전송 된 데이터는 서버에 수신되어 클라이언트로 다시 전송되어야합니다.
