Question

I am currently working on a server in Python, the problem I am facing is the client could not retrieve the sent data from server.

The code of the server is:

import sys
import socket
from threading import Thread

allClients=[]

class Client(Thread):

    def __init__(self,clientSocket):
                Thread.__init__(self)
                self.sockfd = clientSocket #socket client
                self.name = ""
                self.nickName = ""

    def newClientConnect(self):

      allClients.append(self.sockfd)
      while True:
            while True:
                try:
                    rm= self.sockfd.recv(1024)
                    print rm

                    try:
                        self.sockfd.sendall("\n Test text to check send.")
                        print "Data send successfull"
                        break


                    except socket.error, e:
                        print "Could not send data"

                    break

                except ValueError:
                       self.sockfd.send("\n Could not connect properly")


    def run(self):
                self.newClientConnect()
                self.sockfd.close() 
                while True:
                        buff = self.sockfd.recv(1024)

                        if buff.strip() == 'quit':
                            self.sockfd.close()
                            break # Exit when break
                        else:
                            self.sendAll(buff)
#Main
if __name__ == "__main__":

    #Server Connection to socket:
    IP = '127.0.0.1'
    PORT = 80
    serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    serversocket.setsockopt( socket.SOL_SOCKET, socket.SO_REUSEADDR,1)

    print ("Server Started")
    try:
        serversocket.bind(('',5000))
    except ValueError,e:
        print e
    serversocket.listen(5)

while True:
        (clientSocket, address) = serversocket.accept()
        print 'New connection from ', address
        ct = Client(clientSocket)
        ct.start()

__all__ = ['allClients','Client']

#-- 

And the client connecting is:

import socket

HOST = '192.168.1.4'    # The remote host
PORT = 5000              # The same port as used by the server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))

data = s.recv(1024)
s.close()
print 'Received', data#repr(data)

In need of a quick solution….
Thanks,

I tested out your code, and when I commented out

rm= self.sockfd.recv(1024)
print rm

it worked fine. Basically the server stopped there to wait for a message that never came. If it still does not work for you, there might be two problems. Either you have a firewall that blocks the connection somehow, or you have old servers running in the background from previous tries that actually wasn’t killed. Check your processes if pythonw.exe or equivalent is running when it shouldn’t be, and kill it.
