#88251 — TCP sockets python timeout public IP adresss

I am trying to communicate between a server and client using TCP sockets. 

Server code:

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 = ('my-server-ipadress', 1999)
    print >>sys.stderr, 'starting up on %s port %s' % server_address
    sock.bind(server_address)
    sock.listen(1)
     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()

Client code:

    from socket import *
    
    clientsocket = socket(AF_INET,SOCK_STREAM)
    
    clientsocket.connect(("my-server-ip-address",1999))
    
    recv = clientsocket.recv(1024)
    
    print(recv)

It is working fine on a local connection. The problem I am facing is when I run the client code on my laptop (using my home wifi network)and try to communicate with the remote server, it is not able connect to the server. What could be the problem ? Any changes in the code required, or do I need to disable firewall on my laptop ?

The error I get is, error: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Changed server code to the following,

from socket import *

HOST = ''
PORT = 8080
serversocket = socket(AF_INET,SOCK_STREAM)
serversocket.bind((HOST,PORT))
serversocket.listen(5)
while True:
    (clientsocket, address) = serversocket.accept()
    print ("Got client request from",address)
    clientsocket.send("Thank You for connecting")
    clientsocket.close()



Still getting same error.

I haven't looked at your code but just taking at face value that it does 
work internally.

Next thing to check is whether you have permission to open arbitrary 
ports on the server and whether they are firewalled off. For example, I 
have a shell account on the server that hosts my webpages and I can run 
ftp / scp to move files across the internet. However, I cannot open say 
port 54321 to the internet and accept connections on it.

I am using windows 8 and python 2.7.7. I did an nmap to my server to identify the list of open ports on my server. I found out that only three ports are open. How do I add a port to the list of open ports on my server ?
server version:
Linux hostname 3.13.0-48-generic #80-Ubuntu SMP Thu Mar 12 11:16:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Ask the system administrator.

	That's an OS/Firewall question -- nothing to do with Python itself.

That's an impressive reply gap. 

If anyone's wondering, this is apparently in reply to this from March:
