How to fix Error 61 (Mac) and Error 10061(Windows) using Python 2.7.3 -

i attempting create basic lan socket server, works correctly when utilize both client , server on same computer. when effort utilize client , server on 2 computers (mac , windows) connection consistently refused on client side. here error got on mac:

traceback (most recent phone call last): file "/users/*****/desktop/client v2.py", line 31, in <module> s.connect((host, port)) file "/library/frameworks/python.framework/versions/2.7/lib/python2.7/socket.py", line 224, in meth homecoming getattr(self._sock,name)(*args) error: [errno 61] connection refused

on windows had same error, number different. have turned off windows firewall both incoming , outgoing connections, , confused actual issue is. here code had ports:

client

#get host , port info connect host = 'localhost' port = input ("what port number?")

i not sure if these lines necessary, perhaps root cause of problem:

try: remote_ip = socket.gethostbyname(host) except socket.gaierror: #could not resolve print "hostname not resolved. exiting" sys.exit()

and finally, actual code connects. (i called socket s) s.connect((host, port))

server

host = 'localhost' #symbolic name meaning available interfaces port = input ("enter port number (1 - 10,000)") s = socket.socket(socket.af_inet, socket.sock_stream) print "socket created" try: s.bind((host, port)) except socket.error, msg: print "bind failed. error code : " + str(msg[0]) + " message " + str(msg[1]) sys.exit() print "socket bind complete" s.listen(10) print "socket listening"

i have done silly, can please tell me error (or if possible cross-os). posted here, no 1 responded. have several other questions there, , great if effort reply them.

host = 'localhost' #symbolic name meaning available interfaces

doesn't mean "all available interfaces" local machine via special interface visible programs running on same computer.

host = '0.0.0.0' #symbolic name meaning available interfaces

does mean available network interfaces. of course of study can bind specific network interface, in case come in ip address in field.
