python - <class 'socket.error'>([Errno 111] Connection refused) -

i'm working on home automation app using python, since migration local setup 2 physical machines(server, client) getting connection refused error:

traceback (most recent call last): file "/opt/web-apps/web2py/gluon/restricted.py", line 227, in restricted exec ccode in environment file "/opt/web-apps/web2py/applications/home_plugs/controllers/default.py", line 85, in file "/opt/web-apps/web2py/gluon/globals.py", line 393, in self._caller = lambda f: f() file "/opt/web-apps/web2py/gluon/tools.py", line 3440, in f return action(*a, **b) file "/opt/web-apps/web2py/applications/home_plugs/controllers/default.py", line 32, in toggle gpio.setup(light.onpin,gpio.output) file "applications/home_plugs/modules/gpioclient.py", line 23, in setup file "applications/home_plugs/modules/gpioclient.py", line 18, in send host = '192.168.1.79' file "/usr/lib64/python2.7/socket.py", line 224, in meth return getattr(self._sock,name)(*args) error: [errno 111] connection refused

server code:

#!/usr/bin/env python import socket import rpi.gpio gpio import sys import logging  setup = chr(0) output = chr(1)  gpio.setmode(gpio.board)  def gpio_setup(data):     pin,dir = ord(data[0]),ord(data[1])     gpio.setup(pin,dir)     logging.gpioserverlog("setup" + str(pin) + str(dir))     return 0  def gpio_output(data):     pin,val = ord(data[0]),ord(data[1])     gpio.output(pin,val)     logging.gpioserverlog("out" + str(pin) + str(val))     return 0  if __name__=='__main__':     host = ''     port = 21567     bufsiz = 1024     addr = (host, port)     serversock = socket.socket()     serversock.bind(addr)     serversock.listen(5)      while 1:         ret = none         logging.gpioserverlog('waiting connection...')         clientsock, addr = serversock.accept()         logging.gpioserverlog('...connected from:' + str(addr))         data = clientsock.recv(bufsiz)         if data[0] == setup:             ret = gpio_setup(data[1:])         elif data[0] == output:             ret = gpio_output(data[1:])          if  ret:         clientsock.send('thank conencting')             clientsock.send(ret)             clientsock.close() 

client code:

#!/usr/bin/env python # coding: utf8  import socket import struct  setup_cmd = chr(0) output_cmd = chr(1)  output = chr(0) input = chr(1)  on = chr(1) off = chr(0)  def send(data):      sock = socket.socket()      host = '192.168.1.79'      port = 21567      sock.connect((host,port))      sock.send(data)      sock.close  def setup(pin,dir):     data = struct.pack("ccc",setup_cmd,chr(pin),dir)     send(data)  def output(pin,val):     data = struct.pack("ccc",output_cmd,chr(pin),val)     send(data) 

machines: server - raspbian wheezy/python 2.7 client - centos 7/python 2.7

i have disabled firewalls ensure no blocking of connections. telnet works

i have test client.py script whihc works when ran client commandline:

#!/usr/bin/python # client.py file  import socket               # import socket module import gpioclient gpio import time  gpio.setup(11,gpio.output) gpio.output(11,gpio.on) time.sleep(1) gpio.setup(11,gpio.input) 

any appreciated

any more information require please let me know

thanks in advance

turns out there 2 incorrect carriage returns in gpioclient.py

remove , working
