# 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):
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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.
|
|
|
|
```bash
|
|
wget http://<CacheServerIP>/mscomtest/wuidt.gif?cacheHostOrigin=au.download.windowsupdate.com
|
|
```
|
|
|
|
If successful, you will see a terminal output similar to the following:
|
|
|
|
```bash
|
|
HTTP request sent, awaiting response... 200 OK

|
|
|
|
Similarly, enter the following URL into a web browser on any device on the network:
|
|
|
|
```http
|
|
http://<CacheServerIP>/mscomtest/wuidt.gif?cacheHostOrigin=au.download.windowsupdate.com
|
|
```
