Mosquitto on Windows with TLS enabled and DH params provided fails
When configuring Mosquitto on Windows with TLS enabled and providing DH (Diffie-Hellman) parameters, there are a few steps to follow. Here's a general guide to setting up Mosquitto with TLS and DH parameters on Windows:
Generate DH parameters: Use the
openssl
command-line tool to generate the DH parameters. Open a command prompt and navigate to the directory where you have OpenSSL installed (e.g.,C:\OpenSSL\bin
).Run the following command to generate the DH parameters:
csharpopenssl dhparam -out dhparams.pem 2048
This command generates 2048-bit DH parameters and saves them to a file called
dhparams.pem
. Adjust the path and filename as needed.Configure Mosquitto: Edit the Mosquitto configuration file (
mosquitto.conf
) to enable TLS and specify the DH parameters.Open the
mosquitto.conf
file in a text editor and make the following changes:Enable TLS by adding the following lines:
javascriptlistener 8883
cafile C:/path/to/ca.crt
certfile C:/path/to/server.crt
keyfile C:/path/to/server.key
Adjust the paths to the CA certificate (
ca.crt
), server certificate (server.crt
), and private key (server.key
) according to your setup. Ensure that these files are correctly generated and available.Specify the DH parameters by adding the following line:
javascriptdhparamfile C:/path/to/dhparams.pem
Adjust the path to the DH parameters file (
dhparams.pem
) that you generated in step 1.
Start Mosquitto: Start the Mosquitto broker with the updated configuration.
Open a command prompt and navigate to the directory where Mosquitto is installed (e.g.,
C:\Program Files\mosquitto
).Run the following command to start the Mosquitto broker:
rmosquitto -c mosquitto.conf
Mosquitto will start and use the specified TLS settings and DH parameters.
Make sure to adjust the paths and filenames in the configuration file to match your specific setup. Also, ensure that the certificate files (ca.crt
, server.crt
) and private key file (server.key
) are correctly generated and available.
By following these steps, you should be able to configure Mosquitto on Windows with TLS enabled and DH parameters provided.
