zeromq

I'm using zeromq to develop a dynamic application which operate like upnp protocol( autoconfiguration and auto-discovery of equipment on a living room). To do it so, i use zeromq to distribute messages, my problem is that when i create a socket and binding on a adress "169.254.1.0 through 169.254.254.255" , I receive a error messages like this: ZMQError: Cannot assign requested address . I've tried to figure out why by changing the address by local adress (127.0.0.1),and it's works !!. The problem is that i'm implementing autoip, it's means that i'm oblliged to use the adresse on range 169.254

Consider the example code below (I typed it up quickly as an example, if there are errors it doesn't matter - I'm interested in the theory). bool shutDown = false; //global int main() { CreateThread(NULL, 0, &MessengerLoop, NULL, 0, NULL); //do other programmy stuff... } DWORD WINAPI MessengerLoop( LPVOID lpParam ) { zmq::context_t context(1); zmq::socket_t socket (context, ZMQ_SUB); socket.connect("tcp://localhost:5556"); socket.setsockopt(ZMQ_SUBSCRIBE, "10001 ", 6); while(!shutDown) { zmq_msg_t getMessage; zmq_msg_init(&getMessage); zmq_msg_recv (&getMessage, socket, 0); //This line will

I am seeking Python 2.7 alternatives to ZeroMQ that are released under the BSD or MIT license. I am looking for something that supports request-reply and pub-sub messaging patterns. I can serialize the data myself if necessary. I found Twisted from Twisted Matrix Labs but it appears to require a blocking event loop, i.e. reactor.run(). I need a library that will run in the background and let my application check messages upon certain events. Are there any other alternatives? Give nanomsg , a ZeroMQ younger sister, a try - same father, same beauty Yes, it is licensed under MIT /X11 license. Yes

I implemented the Last Value Caching (LVC) example of ZMQ ( http://zguide.zeromq.org/php:chapter5#Last-Value-Caching ), but can't get a 2nd subscriber to register at the backend. The first time a subscriber comes on board, the event[0] == b'\x01' condition is met and the cached value is sent, but the second subscriber (same topic) doesn't even register ( if backend in events: is never true). Everything else works fine. Data gets passed from the publisher to the subscribers (all). What could be the reason for this? Is the way the backend is connected correct? Is this pattern only supposed to

I'm trying to use spyne ( http://spyne.io ) in my server with ZeroMQ and MsgPack. I've followed the examples to program the server side, but i can't find any example that helps me to know how to program the client side. I've found the class spyne.client.zeromq.ZeroMQClient , but I don't know what it's supposed to be the 'app' parameter of its constructor. Thank you in advance! Edit: The (simplified) server-side code: from spyne.application import Application from spyne.protocol.msgpack import MessagePackRpc from spyne.server.zeromq import ZeroMQServer from spyne.service import ServiceBase from

I'm hoping to get the CurveCP functionality working within ZeroMQ ØMQ. I'm using CentOS as the underlying OS. After downloading and running ZeroMQ, I've done the usual ./configure , make and sudo make install . Then running make check returned many test passes, but stated: libsodium not installed, skipping CURVE test So sudo yum install libsodium and sudo ldconfig , then make clean , and the commands above. But next time I ran the make check , the CURVE test is skipped, again reporting no libsodium. Looking at the tests, I see test_security_curve.cpp has #ifndef HAVE_LIBSODIUM and that
