Well any client can pick their own keypair, so unless you have the public key
then it's moot. If the client claims to be billgates and signs their message
(and you have their pubkey) then they're authenticated, no?

Yes, definitely UDP transport would be a major added value.
For many industrial control systems, UDP is the solution when we talk
about:
- high frequency (50Hz) messaging
- scalability: minimal load use of resources on publisher's side

unordered UDP would be great for many usecases. I have no need for the
guarantees offered by TCP.
The only thing that's worth thinking about is congestion failure and ZMQ would
need some mechanism to avoid this (which is part of TCP).

both clients use their own curve
Zmq poller can also wake on standard file descriptors (eg unix socket). If your
custom event can write to a unix socket or pipe you might be in luck.

Diego,
Thanks! I’ve been looking for someone with whom to engage the C4 process for
fszmq.
As for NetMQ, I imagine it should “just work” with F# (in terms of raw
functionality). Although, like many C# libraries, it may benefit from a thin
layer of code to make it “F#-friendly”. If so, this
Hi Devs,
In *StreamQ-Proxy*, I test that in the handcheck, I have CURVE, then

Instead, I have to use:
!memcmp(content + *3*, READY, 5)

Is it a misunderstanding of mine or a discrepency between the RFC and

I've stated why I'm not going to invest in GSoC in any way except to

Experimentation is always good, if we learn from it.

Yes, if the client claims to be billgates and signs their message with the
known publickey, then they’re authenticated. The question is, did they do
this? Or not?
Let me now be more detailed about the problem. The problem is to correlate an
incoming message with a publickey of the sender.

I’m reasonably sure we have the same problem, and I’ve gotten somewhat further

Hi,
I'm building an embedded device on an ARM target, using ZMQ library for
communication among processes. This normally works well, but I've encountered
a problem: If I build a simple daemon (background stand-alone app), or run
ZMQ-PHP extension in (Lighttpd), the app hangs when zmq_socket()

Hi Drew,
Yes indeed,
I think I can supply a patch that is at least good enough to get cleaned up and
merged by a zmq dev. The open question at this point is which way the
correlation should get resolved. One possibility is to populate the ZAP
identity with the router identity instead of the empty string. Another

With asynchronous IRC software, you can choose your nickname and a topic.
You send messages that belong to a topic.
People who subscribed to that topic receive your message.
Or they might choose to receive messages from every topic.
This becomes very interesting when population density goes up
This is a great idea! Like #hashTags
