Client does not have read permissions

saturn

Hello.
I have created the role "mqtt" as at attached screenshot.
User "house" is the member or the "mqtt" role.
I have created the gateway "House" with settings as at attached screenshot.
When I try to enable this gateway, I get the following in the log:

2018-05-24 15:23:41,517 ERROR [nioEventLoopGroup-3-12] [io.moquette.spi.impl.ProtocolProcessor:851] Client does not have read permissions on the topic CId=house-mqtt-client_44gNx, username=house, messageId=1, topic=house-out/#

What's my mistake?

jkandasa

@saturn on the role you should add /# as follows,

Topics publish: house-in/#, house-out/#
Topics subscribe: house-in/#, house-out/#

saturn

Thank you.
It's working now.
Is it posible to use mask or regexp for topics in the role?

@saturn

Is it possible to use mask or regexp for topics in the role?

I hope it should,

You can see the actual code here.

// _topic: defined in role
// topic: recived from client
 _topic = _topic.replaceAll("\\+", "\\\\w+").replaceAll("#", "\\.*");
 if (topic.matches(_topic)) {
     return true;
 }

This code replaces,

+ to \w+ (Example: house-out/+/+/+ becomes as house-out/\w+/\w+/\w+)
# to .* (Example: house-out/# becomes as house-out/.*)

And finally matches the received topic from the client(matches as a regular expression).

So your regular expression on the role might work. (if it does not have + and # symbol)

I have got error again:

2018-05-30 00:14:40,149 ERROR [nioEventLoopGroup-8-10] [io.moquette.spi.impl.ProtocolProcessor:851] Client does not have read permissions on the topic CId=house-1, username=house, messageId=2, topic=house-in/+/+/+/+/+

My options not help:
Topics publish

house-in, house-in/#, house-in/+/+/+/+/+, house-in/\w+/\w+/\w+/\w+/\w+, house-out/+/+/+/+/+, house-out/\w+/\w+/\w+/\w+/\w+

Topics subscribe

house-out, house-out/#, house-out/+/+/+/+/+, house-out/\w+/\w+/\w+/\w+/\w+, house-in/+/+/+/+/+, house-in/\w+/\w+/\w+/\w+/\w+

What I do wrong again?

jkandasa

@saturn Use + or # only.

use only house-in/#, house-out/# will cover everything.

Can you elaborate how you want to control topic? I can give some examples.

saturn

When I use only "house-in/#, house-out/#" in "Topics publish" and "Topics subscribe" I get the same error:

ERROR [nioEventLoopGroup-8-10] [io.moquette.spi.impl.ProtocolProcessor:851] Client does not have read permissions on the topic CId=house-1, username=house, messageId=2, topic=house-in/+/+/+/+/+

I want to control MySensors network by sending data to the "house-in" and get statistic and status information from "house-out".

saturn

May be I misunderstand you.
I think you mean that, I should use

instead of

\w+

and

instead of

.*

in role's settings.
But my problems with read permissions was resolved only when I add

house-out/.*, house-in/.*

to the role's settings.
Thank you for your help.

@saturn

This one does not work for you?

house-out/#, house-in/#

saturn

@jkandasa
With

house-out/#, house-in/#

I get

Client does not have read permissions on the topic CId=house-1, username=house, messageId=2, topic=house-in/+/+/+/+/+```

jkandasa

@saturn

house-out/#, house-in/#

You should add this to both subscribe and publish topics. Can you show your MQTT client code?
