How do you set MQTT username and password?

poldim commented 7 years ago

I've got an MQTT running in a docker and have it exposed to the web so I've enabled password protection to keep intruders out. How can I pass through my credentials from cgateweb to the MQTT server?

I've added password support, you need to add it in the settings file. Let me know if it works fine for you.

Thanks for working on this!

I've updated the index and settings files and went form a Error: Connection refused: Not authorized to the error below. I also tried intentionally using the wrong username/password and the error was the same.

Just in case, could you double check that the index.js on your machine matches what's in github? It looks like somehow somewhere a js file has some html in it, but I'm not exactly sure where or how... https://github.com/the1laz/cgateweb/blob/master/index.js

Maybe worth checking settings.js as well.

I decided to start over and removed the cgateweb folder to eliminate any update conflicts. C-Gate registers the connection from node and then instantly closes it as it fails to connect to the MQTT broker. I tried to see if there is an option for "trusted connections" in mosquitto to see if I can get around it that way but did not find anything.

Hmm, weird. I've tested on mosquitto here and it works. I image there's possibilities of version differences, but I'd expect some different error. You've definitely got both your username and password in settings.js and uncommented those two lines?

yessir

my password has an ! and # in it - could that be breaking it or are the single quotes around it making it a whole var?

the1laz commented 7 years ago

Alright. I might try a fresh install on a different pi when I'm back at my computer then, see if I'm missing something.

the1laz commented 7 years ago

No, I don't think there's any problem with ! or #. As long as there are no quotes in the password and as long as you've removed the slashes from in front of those lines, should work. I just tested on mine using password!# and it connected fine.

the1laz commented 7 years ago

I just tried this on a different pi:

git clone https://github.com/the1laz/cgateweb.git cd cgateweb npm install nano settings.js -- changed the cbus ip -- changed the mqtt ip -- deleted the // from username and password, entered my testing usernames and password: exports.mqttusername = 'user1'; exports.mqttpassword = 'password!#'; then ran it with node index.js

Connected without issue. Did you do anything different with your install?

I set up password on mosquitto by creating a password file with this in it: user1:password!# then ran mosquitto_passwd -u passwordfilename then copied the file into /etc/mosquitto edited /etc/mosquitto/mosquitto.conf -- added the line password_file /etc/mosquitto/passwordfilename -- added the line allow_anonymous false restarted the service.

Any differences there?

I'm not sure where else to look, since we'll be using the same version of the mqtt module and we're both using a rasppberry pi.

Haven't got any more feedback, working for me.

use can use this. var mqtt = require('mqtt'), url = require('url'); // Parse var mqtt_url = url.parse(process.env.CLOUDMQTT_URL || 'mqtt://localhost:1883'); var auth = (mqtt_url.auth || ':').split(':'); var url = "mqtt://" + mqtt_url.host;

var options = { port: mqtturl.port, clientId: 'mqttjs' + Math.random().toString(16).substr(2, 8), username: auth[0], password: auth[1], };

// Create a client connection var client = mqtt.connect(url, options);
