Hello Cornelius and Justin,
I was at last able to get my forwarder to work and it was my mistake.
My sender code which was like:
def sendMessage():
context = zmq.Context()
sender = context.socket(zmq.PUB)
sender.bind('tcp://127.0.0.1:5558')
sender.send("This is the sender")
was the actual problem, i got to know from my reading that call to socket.bind
should happen only once, so i changed my sender code to
something like:
socket = context.socket(zmq.PUB)
socket.bind('tcp://127.0.0.1:4443')
def sendMessage(socket,message):
try:
socket.send(message)
except:
print "Unable To Send Message"
and than i was able to send messages but this gets me into two three more
problems, i hope you guys will help me out is giving me some
ideas about this.

From the looks of your code https://gist.github.com/2119078,
you define functions for sending and receiving messages, but you do not call
them, like you do with Forwarder.py.
Also for the sake of easier testing, you may want to have your sender script to
send multiple messages to allow you to see what's going on.--

Thanks for your reply cornelius.
I am now using netstat for checking the blocked ports.
Meanwhile i have uploaded the code here https://gist.github.com/2119078
and there is no proprietary code at the moment its the basic code where i am
trying to get the forwarder working.
and your last point is very valid, i start first the forwarder, than i start
the receiver and than the sender to send messages. From this the point you have
mentioned can be a problem.
I will be grateful if you can just have a look at the code its very small and
let me know if i am doing some wrong.
Regards,
Ronald

Ronald,
You can use netstat. You're using windows, right?
http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/netstat.mspx?mfr=true
As for debugging your code, can you paste the code into a paste bin or
gist.github?Try this for instance: https://gist.github.com/
You omit out any code that is proprietary if this for work or
research.
After you check your ports, you should think about whether the order in which
ports are being opened is an issue. For instance, your forwarder device binds
the outgoing port, but what if the receiver thread starts before the device?

Hello Justin,
Thanks again for reply.
I have tried restarting the platform, and i have also checked it in two
different machines, and in both machine it doesn't work.
I am clue of ideas how to debug this problem as the no of line of code is very
small too.
Is there any way i can diagnose that the port is closed or blocked something
like that.
Thanks,
Ronald
