Re: TCP sockets python timeout public IP adresss
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 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

Thanks guys everything worksfine.

Communicating with multiple clients using one TCP socket pyt
I am using TCP sockets to communicate between my server and clients. The server
code and socket code are as below:
server:
from socket import *
HOST = 'xx.xx.xx.xx'
PORT = 1999
serversocket = socket(AF_INET,SOCK_STREAM)
serversocket.bind((HOST,PORT))
print 'bind success'
serversocket.listen(5)
print 'listening'
while True:
(clientsocket, address) = serversocket.accept()
print ("Got client request from",address)
#clientsocket.send('True')
data = clientsocket.recv(1024)
print data
clientsocket.send('True')
clientsocket.close()
client:
import socket
import sys
# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# Connect the socket to the port on the server given by the caller
server_address = ('xx.xx.xx.xx', 1999)
print >>sys.stderr, 'connecting to %s port %s' % server_address
sock.connect(server_address)
try:
message = 'This is the message. It will be repeated.'
print >>sys.stderr, 'sending'
for x in range (0,1):
name=raw_input ('what is ur name')
print type(name)
sock.send(name)
print sock.recv(1024)
finally:
sock.close()
I am able to communicate with the server from client and able to send and
receive data. But the problem I am facing is that I am not able to send and
receive data continuously from the server. I have to restart my client code on
my laptop to send and receive data again from the server. The way the above
client code is working is that when I give a keyboard input, then the socket
sends data to server and server responds back. But in the client code, in the
for loop if I do two iterations, for the second iteration the data I enter from
keyboard is not reaching server. I need to restart my client code to send data
again. How do I fix this ?
Also, when once client is connected to the server, the other cannot connect to
the server. Any ideas on how to do this ?
