I have configured MQTT Mosquitto and enabled SSL and i have connected securely using certificates cafile, certfile and keyfile tested using MQTT.FX client.
The problem is , is there any way to enable TPM engine which can store certificates in it and connect to MQTT client.
I have refered this link
https://mosquitto.org/man/mosquitto-conf-5.html
This is an OpenSSL capability that Mosquitto is just exposing some of the config for.
Have a look at something like this which is a plugin to add TPM2.0 support

I am running mosquitto broker on ubuntu on aws ec2, using TLS over port 8883. For example :
mosquitto_sub -h domain.com -t topic --cafile /etc/mosquitto/certs/ca.crt -p 8883
The client is esp8266 using TLS configuration.
Is it possible for someone to still intercept or read the outgoing or incoming mqtt message?
All communication is on port 8883 using a certificate.
(1) The most trivial answer with MQTT context is:
Use another MQTT client and subscribe to '#' to see all messages your broker receives from anywhere.
If you know the topics your esp8266 client is publishing or subscribed to,
subscribe to all these with the other client (e.g. with 'mosquitto_sub').
The broker provides messages on the topic "topic" mentioned above to all subscribed clients, independent from their communication channel security.
This way you get the messages for the esp8266 with any other client.
For example, if the unencrypted channel is not deactivated: mosquitto_sub -h domain.com -t topic -p 1883
TLS ensures encryption for the communication channel only, and not for the actual payload before putting it onto the channel between client and server.
(2) If (1) is not the expected answer and you rather want to wiretap the encrypted communication:
Short answer is: no, not with trivial tooling; that's the purpose of TLS.
A good article for MQTT security fundamentals: https://www.hivemq.com/blog/mqtt-security-fundamentals-tls-ssl/
Long answer is:
[Disclaimer: no assumptions about advanced abilities of 3rd parties]
The TLS communication is properly encrypted, and to decrypt the MQTT communication requires the session secrets client and server use after
their successful TLS handshake.
A solutions requires you as the operator of the broker.
There is a short article about how to do it:
https://adrianalin.gitlab.io/popsblog.me/posts/decrypt-mqtt-tls-traffic/
In essence:
You can use Wireshark to eavesdrop the traffic, if you configure the session secrets there.
To get the secrets you adjust and re-build mosquitto according the article, so that your broker print the session secrets.
(Whether you are able to setup this with root privileges on your EC2 instance in AWS, is another question).
I have a freeradius server setup on my ubuntu VM. My Edgecore AP is connected to a MicroTik and Laptop. I have OpenWRT running on the AP and I'm able to connect a client using WPA2 Enterprise encryption. I'm trying to send a CoA request from the VM such as "Session-Timeout" however, observing the logs on the AP, I receive the message I've included in the title. Is CoA completely unsupported or hostapd simply can't understand the incoming request?
Dynamic Authorization Extensions (RFC 5176) is default disabled in hostapd.
set radius_das_port=3799 in your conf to enable this feature.

I'm using Home Assistant OS as a Virtualbox in Windows 10. I'm accessing it via homeassistant.local:8123. So I'm trying to configure my Mosquitto broker in Home Assistant. It wants to know my broker address. I'm guessing I need to use an ip. Where do I find this? Should I use localhost, 127.0.0.1, homeassistant.local or maybe an unused ip like 192.168.1.99 from my router?
If you are following this page, I find it is a bit misleading. Hope the following steps help you.
Install mosquitto (broker)
Suggest follow official github doc to configure mosquitto addon; (This step doesn't require IP configure)
Configure client integration within home assistant
Refer to here for your client integration, use localhost for your ha integration to connect your mosquitto broker;
Configure MQTT client outside home assistant
you need to find the exposed IP of your mosquitto broker, in your case, it shall be your VM's IP.
I hosted Mosquitto MQTT broker on Ubuntu in Digital Ocean Cloud droplet. It's domain name is instrux.live and IP of the domain is 192.34.63.138. I publish and subscribe messages from two terminal windows and it worked fine.
When I tried to connect it with the android using Paho MQTT android client it could not connect. I also checked its connection with the MyMQTT android application and it did not connect. After making sure the android code has not any error, I again checked its connection with the Eclipse Paho Javascript client on eclipse.org website and it did not connect. Now, I have realized there might be something missing or wrong in my broker configuration which is not allowing it to get connected with other clients remotely. I have also opened firewall for ports 1883 for Android client and 8083 for the Javascript client and still it is not connecting.Here is mosquitto configuration file:
allow_anonymous true
password_file /etc/mosquitto/passwd
listener 1883
protocol mqtt
listener 8083
protocol websockets
Since the error is "Connection Refused" rather than a timeout I suspect that you have not configured the firewall to allow inbound traffic on port 8083.
You may need to do this both on the machine it's self and in Digital Ocean's console.
We are developing an application which needs to consume AWS IoT service based on a MQTT protocol deviation. We are currently facing issues to get connected with MQTT broker provided by AWS IoT cloud server.
Following is the environment:
iOS Version: 8.0 / 9.0
Programming language: Swift
Library for MQTT: Moscapsule
Steps followed:
Set initial config clientid, host, port
Set client certificate with private key, providing .pem file path (e.g. cert.pem, privateKey.pem)
Set server certificate which is root certificate .pem file path (e.g. rootCA.pem)
Set tls opts with tsl_insecure: false, cert_reqs: SSL_VERIFY_PEER, tls version: tlsv1.2, ciphers: nil
Problems faced:
When trying to connect to server/broker gives error “unable to create TLS_Context”.
With setting tls cert_reqs: SSL_VERIFY_NONE, gives connection status success with subcribe and publish sucess, but doesn’t reflect on server or broker.
Any help in this context is highly appreciable.
The AWS SDK for iOS already supports connecting to AWS IoT over MQTT. You can see an example Swift program which transfers data to and from AWS IoT over MQTT using certificate-based authentication here. If you'd like to use a different MQTT client and just need to know how to set it up, you might start with the AWS SDK for iOS, and then have a look at the code involved in setting up the TLS connection.
Thanks for using AWS IoT.
