Verify cache node functionality
Verify client side
Sign in to the Connected Cache server or use SSH. Run the following command from a terminal to see the running modules (containers):
sudo iotedge list
If the cache server is running properly, you will see the containers edgeAgent, edgeHub, and [Your Cache Node name] listed, all with the status running.
If it lists the edgeAgent and edgeHub containers, but doesn't include MCC, view the status of the IoT Edge security manager using the command:
sudo journalctl -u iotedge -f
This command provides the current status of the starting and stopping of a container or the container pull and start.
Verify server side
It can take a few minutes for the container to deploy.
To validate a properly functioning MCC, run the following command in the terminal of the cache server or any device in the network. Replace <CacheServerIP> with the IP address of the cache server.
wget http://<CacheServerIP>/mscomtest/wuidt.gif?cacheHostOrigin=au.download.windowsupdate.com
If successful, you will see a terminal output similar to the following:
HTTP request sent, awaiting response... 200 OK

Similarly, enter the following URL into a web browser on any device on the network:
