# Test the connection to Hermes through the ADCv2 gateway

# Test the connection to Hermes through the ADCv2 gateway {#ariaid-title1}

* Release version: Xanadu

* ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read

Verify the keystore and truststore have been correctly generated by testing the connection to Hermes through the ADCv2 gateway.

## Before you begin

* Role required: integration_hub_admin
* This page is part of the [Stream Connect quick start guide](https://www.servicenow.com/docs/CgUs89feYBPqwrM~4fKGXg "This quick start guide gives you an overview of how to set up and use each of the six Stream Connect producers and consumers to exchange data between your ServiceNow instance and a Kafka environment.").
* This document covers how to test a connection to Hermes. To create the connection, see [Set up a secure connection to the Hermes Messaging Service](https://www.servicenow.com/docs/access?context=set-up-secure-connection-to-hermes&version=xanadu&pubname=xanadu-servicenow-platform&ft:locale=en-US).

## Procedure

1. Download and install Apache Kafka.
   1. Download the [Apache Kafka](https://kafka.apache.org/downloads) binaries.
   2. Unzip the Kafka package by running the following command:  

          tar -zxvf kafka_2.13-3.1.2.tgz

   {#test-connection-hermes__substeps_ffg_hvp_twb}
2. Navigate to the Kafka directory by running the following command:  

       cd kafka_2.13-3.1.2

3. Configure a producer.
   1. Open the config/producer.properties file.
   2. Configure the following SSL properties:  

          security.protocol=SSL

          ssl.truststore.password=<truststore password>

          ssl.truststore.location=<path to truststore.p12>

          ssl.truststore.type=PKCS12

          ssl.keystore.password=<keystore password>

          ssl.keystore.location=<path to keystore.p12>

          ssl.keystore.type=PKCS12

          ssl.key.password=<keystore password>

      Replace the following placeholder variables:
      * `<truststore password>` with your truststore password.
      * `<path to truststore.p12>` with the path to your truststore file.
      * `<keystore password>` with your keystore password.
      * `<path to keystore.p12>` with the path to your keystore file.
      {#test-connection-hermes__ul_tvh_twp_twb}

   {#test-connection-hermes__substeps_jt5_lwp_twb}  
   After following steps 1 through 3, you should have downloaded Apache Kafka and configured the producer.properties correctly. All the commands given in next steps should run within the Apache Kafka home directory.
4. Copy the config/producer.properties file to config/bootcamp.properties.  
   This example uses `bootcamp` as a generic name.

       cp config/producer.properties config/bootcamp.properties

5. Use the following command to list the topics.  

       bin/kafka-topics.sh --list --command-config config/bootcamp.properties  --bootstrap-server <instance name>.service-now.com:4000,<instance name>.service-now.com:4001,<instance name>.service-now.com:4002,<instance name>.service-now.com:4003

   Be sure to replace `<instance name>` with the name of your instance.  
   If there are topics in the instance, they should be listed here.
