[02:26] justanewbie	Hi,i've installed the zeromq,but i cannot find a executable named zmq_server,just zmq_queue,zmq_streamer,zmq_forward,why?
[02:27] justanewbie	i wanted to know how to write config file of zmq_queue,but don't know how
[02:32] mikko	justanewbie: what are you trying to achieve?
[02:32] mikko	justanewbie: just run a device?
[02:32] mikko	i don't think the device configuration files are documented at the moment
[02:33] mikko	it should be fairly easy to decipher the config from the code
[02:33] mikko	https://github.com/zeromq/zeromq2/blob/master/devices/zmq_streamer/zmq_streamer.cpp
[02:33] mikko	for exampe that
[02:35] justanewbie	thank u mikko,i'll take a look and c
[04:51] neopallium	Hey everyone, I just wanted to let you know about this https://github.com/Neopallium/lua-handlers lua project that I created it wraps lua-ev(event loop) & lua-zmq(requires ZeroMQ 2.1.0). It makes it easy to work with many zmq/tcp/udp sockets in non-blocking mode.
[07:37] sustrik	naopallium: announce it on the mailing list rather, there's much more people there
[09:44] cods	Hi. Just to make sure I understand: for any type of 1-1 connection (push/pull, pub/sub, req/rep), it doesn't matter which side do a connect and which one do the bind, right? (of course, differences occurs when talking about 1-n or n-n)
[10:03] cods	ok
[10:07] neopallium	cods: from what I know it doesn't even matter with 1-n or n-n connections.
[10:11] cods	neopallium: well, I meant that when reversing role (binder/connecter) you have to adapt code to create many socket (connect) instead of one (bind) if you're the server for example, but apart from that, I understand what you mean (messages will be handled the same way at the end I guess)
[10:16] neopallium	looks like you can bind & connect on the same zmq socket
[10:17] neopallium	I just modified one of my test scripts which creates a PUB socket and had it bind to port 5555 and connect to port 5556
[10:18] neopallium	on port 5556 was a script with a SUB socket
[10:18] neopallium	both server & client SUB sockets where able to receive messages from the PUB socket.
[10:18] neopallium	I didn't even think that was possible until now.
[10:19] cods	oh, that's interesting. I have not seen that documented.
[10:20] neopallium	I have read somewhere in the docs that zmq sockets don't put restrictions on who connects and who binds.
[10:20] neopallium	but I didn't think that applied to binding & connection with the same socket.
[10:22] cods	I like how 0mq is versatile. Great design.
[10:33] sustrik	:)
[10:34] sustrik	neopallium: you can also add the link to your project here:
[10:34] sustrik	http://www.zeromq.org/docs:labs
[11:22] neopallium	sustrik: thanks I just sent an email to the mailinglist.
[11:48] cods	just curious while looking at the data on the wire, what the 0x01 0x01 header means? (before what looks like the "SPB" encoding) Is this documented somewhere? (or alternatively, where is it handled in the source code?)
[15:02] DasIch	i'm currently trying to install pyzmq on a machine running ubuntu 10.10, even with libzmq-dev installed pip install pyzmq reports that a zmq_utils.h is missing
[15:03] DasIch	i wasn't able to find any information regarding this issue is there a ppa i should use?
[15:06] DasIch	ah, ppa:chris-lea-zeromq does the job
[15:07] DasIch	uh no, i get an Assertion failed: !pgm_supported () (zmq.cpp:240)
[15:07] guido_g	DasIch: do the versions of libzmq and pyzmq match?
[15:11] DasIch	pyzmq version is 2.0.10, how do i find out the libzmq version?
[15:12] guido_g	from the package? apt-cache show ...
[15:12] DasIch	ah it's also 2.0.10
[15:13] guido_g	then it seems to be build w/o pgm
[15:14] guido_g	get the source and compile it yourself
[15:14] DasIch	guido_g: ok, thanks
[16:55] cremes	andrewvc: i'm around for about 30m this morning; what's up?
[17:12] cremes	andrewvc: send me a message offline and i'll answer it; i'll be off irc for the next 3 days or so...
[17:13] cremes	merry christmas, everybody!
