I want to make a TCP communication between my computer and server (ubuntu).
The server IP is 203.246.114.176 and its port 30000 is open.
The server is running the following server.py:
import socket import sys # Create a TCP/IP socket sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Bind the socket to the port server_address = ('localhost', 30000) print >>sys.stderr, 'starting up on %s port %s' % server_address sock.bind(server_address) # Listen for incoming connections sock.listen(1) while True: # Wait for a connection print >>sys.stderr, 'waiting for a connection' connection, client_address = sock.accept() try: print >>sys.stderr, 'connection from', client_address # Receive the data in small chunks and retransmit it while True: data = connection.recv(16) print >>sys.stderr, 'received "%s"' % data if data: print >>sys.stderr, 'sending data back to the client' connection.sendall(data) else: print >>sys.stderr, 'no more data from', client_address break finally: # Clean up the connection connection.close() And my computer has client.py:
import socket import sys # Create a TCP/IP socket sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Connect the socket to the port where the server is listening server_address = ('203.246.114.176', 30000) print >>sys.stderr, 'connecting to %s port %s' % server_address sock.connect(server_address) try: # Send data message = 'This is the message. It will be repeated.' print >>sys.stderr, 'sending "%s"' % message sock.sendall(message) # Look for the response amount_received = 0 amount_expected = len(message) while amount_received < amount_expected: data = sock.recv(16) amount_received += len(data) print >>sys.stderr, 'received "%s"' % data finally: print >>sys.stderr, 'closing socket' sock.close() When I run at the server, the output is like this:
starting up on localhost port 30000 waiting for a connection and the ufw status is like this:

And what should I do?
help plz.
