In the parallel pipe example,
zmq_bind (sender, tcp://*:5557);
zmq_connect (sink, tcp://localhost:5558);
and s_send (sink, 0);
s_send (sender, string);
how does the control continues in the first s_send and block on the second
s_send, when I haven't started sink on 5558 port.
?
Hi Pritesh,
You're talking about the task ventilator?
The second send doesn't block. The task pipeline can be a little
puzzling at first; best thing is to draw the design on paper and try
to understand the message flow from piece to piece.

Hi people,
My Pushpin project seems to be getting a lot of attention on HackerNews:

I just wanted to mention that under the hood it's a multiprocess ZeroMQ
architecture. Thanks again for the nice lib. :)

Hello,
I want to build ZMQ for ARM but have problems.
If I just build with the plain old i386 arch, no problems. I do get a .a
library I can statically link against, BTW. Good.
Now if I ./configure ... CC=arm-none-linux-gnueabi-gcc --host=arm
I don't know if this is a 0MQ question or a general networking
question. I know that I'm confused.
I'm troubleshooting some message delivery problems and I've run across
this scenario:
The ESTABLISHED tcp connections on one server don't match the
corresponding connections on the other server.
Unfortunately not, see above. E.g. I have arm-linux-gnueabi here since I
use the EmDebian toolchain.
FYI, I couldn't get zeromq-3.2.2 to compile using my toolchain (Debian
4.4.5-8) due to a bug in decoder.hpp. Fixed the bug myself and was going
to submit a patch but this appears to have been
Thanks Pieter. Does the hand shaking happen at connect? Because suppose
there is a delay after the connect, before the initial send, the send
succeeds.
If the handshaking does happen at connect, and if it is possible to make
sure the connect returns only after the handshaking is done, that
Is there NATing between these two hosts? RFC 5382 has some guidelines on
idle timeout for established connections, you might be hitting that limit.

No NATing that I'm aware of. But this is EC2, so there could be
shenanigans afoot. (Shenanigans btw, is the most advanced descriptor
in my network layer vocabulary.)
The 6 established connections on the router-server are still shown
via netstat -- even after these many hours have passed. If
Are you using their VPC technology or talking over elastic IPs? The
elastic IP stuff does seem to involve some shenanigans, in that it must
forward or somehow bind the public ip to the internal one. If you use VPC,
I don't think there's that translation layer involved.
Other than that, I'm out
Hi Gurus,
I have implemented a dealer (server) and router ( as server) using zmq.
I would like my application to use dealer or router to both send and
receive messages, something like a dealer can send and receive message. Is
this possible ? Please see the code that I have written. This works
It is difficult to help without understanding more detail about your
application, in general yes you can send/recv in any order on router/dealer.

The router has to receive a message from the dealer first, so the return
envelope/s can be determined. After that, I don't think there are any
restrictions.
