Group CHAT not found #141

BananaNosh · 2019-08-10T19:03:49Z

Hey,
I started the example chat application as written in the README.
However, I always get the error message "Group CHAT not found" when sending a message, though the group should have been created and joined.

Hey, Thanks for your response. I used the version exactly as stated in the readme. But my output is: using Python native module No module named 'zyre_pyzmq' <pyre.zsocket.ZSocket object at 0x7f15120df250> <pyre.zsocket.ZSocket object at 0x7f15120df250> Hi Group CHAT not found. <pyre.zsocket.ZSocket object at 0x7f15120df250> {<zmq.sugar.socket.Socket object at 0x7f1515cd9660>: 1} CHAT_TASK: b'Hi' Hello World <pyre.zsocket.ZSocket object at 0x7f15120df250> {<zmq.sugar.socket.Socket object at 0x7f1515cd9660>: 1} CHAT_TASK: b'Hello World' Group CHAT not found. Do you have any idea, what could be the problem? Any port option on my computer or something? Best, Jonathan Am Di., 13. Aug. 2019 um 12:23 Uhr schrieb Arnaud Loonstra < [email protected]>:

no idea, did you start 2 nodes before chatting? what platform are you on? you should see enter events if they see each other.

BananaNosh · 2019-08-13T13:25:55Z

Hi, I am on Ubuntu 18.04.3. If I start the second node, there does not happen anything in the first. At some point some weeks ago, it worked. However I don't know what I should have changed since then. Am Di., 13. Aug. 2019 um 15:15 Uhr schrieb Arnaud Loonstra < [email protected]>:

I also tested it on another device, with Zorin(also Ubuntu based) and it did not work either. Am Di., 13. Aug. 2019 um 15:25 Uhr schrieb Jonathan Loos < [email protected]>:

is this on physical machines or on virtual ones? If they don't see each other is must be something network related. Are you sure you can do broadcasts on these devices? It's hard to guess what's going on on your machines.

You could try the zyre library instead._

BananaNosh · 2019-08-13T13:52:03Z

They are physical machines.
Thanks for your help so far. I will check if I can find out if there is something a problem within my network.

BananaNosh · 2019-08-13T13:54:12Z

But for using zyre I would have to use C, right?

sphaero · 2019-08-13T14:04:27Z

Yes, but it has bindings to python: https://github.com/zeromq/zyre/tree/master/bindings/python

BananaNosh · 2019-09-06T16:23:59Z

Hi, I tried to use the python bindings of zyre, but it did not work either. Therefore, I wanted to ask which version of python you were using during your test above? Thanks in advance Am Di., 13. Aug. 2019 um 16:04 Uhr schrieb Arnaud Loonstra < [email protected]>:

I was using the latest from the master branch. What was the output of the zyre bindings?

tlowrimore · 2019-09-23T16:40:16Z

I'm experiencing the same issue with Pyre. I'm starting two nodes on the same machine, but when I send a message to the group, I receive the "Group CHAT not found". I'm running on Pop_OS 19.04 / Python 3.7.

Cheers!

sphaero · 2019-09-24T07:49:41Z

can you post your output of both nodes?

tlowrimore · 2019-09-24T16:00:48Z

@sphaero Thanks for the quick response. I'm just getting the initial logging output. No indication of discovery. That said, I have to abandon the use of this library due to the use of the LGPL licence.

sphaero · 2019-09-25T09:48:29Z

So it means discovery is failing on your platform. Discovery is done through UDP broadcast. You should see udp broadcast packets on your network interface using tcpdump.
For example

tcpdump -i all -n port 5670

tlowrimore · 2019-09-25T22:46:33Z

@sphaero Well, I feel silly. Turns out, I have very a restrictive set of UFW rules. As such, the initial UDP broadcast is blocked. Adding a rule that allows this to pass solves my issue. Thank you for your help!

BananaNosh · 2019-09-26T09:48:34Z

Hey, I guess I had the same problem. Can't test it out as I recently changed my operating system, but at least it is working now. Thanks for the input. Am Do., 26. Sept. 2019 um 00:46 Uhr schrieb Tim Lowrimore < [email protected]>:
