[zeromq-dev] License of zmq 3.x c++ binding

2013-03-05 Thread Beyer, Marcel
Hi, The initial zmq 2.x C++ binding was part of zmq itself under the LGPL. The binding for 3.x has been moved to a separate project. Is the binding for 3.x still under LGPL? This message and attachment(s) are intended solely for use by the addressee and may contain information that is

Good question. The repository wasn't well set up, no license file and no notes for contributors. The zmq.hpp license was and still is MIT/X11, you can see this in the sources. LGPL won't work since it's not a library. -Pieter On Tue, Mar 5, 2013 at 10:34 AM, Beyer, Marcel marcel.be...@oce.com

[zeromq-dev] Data integrity and security using ZeroMQ over a WAN

2013-03-05 Thread Adam Covitch
Is there a standard approach to ensuring data integrity and security using ZeroMQ? I'm new to this community and don't see an obvious approach. By 'data integrity' I mean that the message recieved is the same as the one sent. We'll mostly be messaging over TCP, which has problems with jumbo

Doesn't ring a bell for me. A few questions… Are all endpoints using 3.2.2 or is it a mix of 3.2.2 and 2.2? What transports are you using (inproc, tcp, ipc)? Are you using XPUB and XSUB directly or are the endpoints actually PUB/SUB but you are seeing a crash in the parent? How many

Thanks for the rapid answer: -Are all endpoints using 3.2.2 or is it a mix of 3.2.2 and 2.2? Everything is 3.2.2 - What transports are you using (inproc, tcp, ipc)? TCP for publishing - Are you using XPUB and XSUB directly or are the endpoints actually PUB/SUB but you are seeing a crash in

I have found that this happens after subscribing from a pub many (4) times to the same string. I have changed the subscriber and now I do not see the crash in the publisher. I am trying to narrow the problem better. I leave the stack in case it gives any clue.

Adam, There are by my count five separate projects working on this; the most promising is Lourens Naudé's TLS transport inside the library; the most usable today is Salt Stack's distributed security model, which should be quite easy to reimplement. I'd suggest reading this:
