EMA Setup Help

diggergraves — Fri, 13 Dec 2024 00:09:53 GMT

Looking for a little help. I got the EMA server set up, bought a certificate, and tried connecting a client to it, but no clients show up in the server.

When I unplug the internet cable on a client PC where the agent is installed, I see an error mentioning dns lookup failed and the fqdn of my ema server (see error below) but that doesn't make sense since I can successfully ping the fqdn from the client PC.

The firewall is also completely opened to the IP address where the client is located.

EMA version 1.14 is installed on a VM hosted on GCP. It's a Windows Server 2022 Version 21H2 (OS Build 20348.2849) and Microsoft® SQL Server® 2022 Express is installed on the same server. I know that's only recommended for POC, and that's basically what I'm trying to accomplish.

Any help or tips are greatly appreciated.

\Agent\MeshManageability\agent\core\meshcore.c:1413 EMA Server DNS lookup failed: ema.mydomain.com No such host is known. . Last error: 11001

Hi diggergraves,

Greetings!

We see that there is an error which says that the DNS lookup failed, however the firewall has also been open to confirm the Ping of the FQDN is resolved,

Please find the plan of action given below and share your observation:

1) Check Network Connectivity:

Ensure that the endpoint has a stable internet connection.
Try to access other websites to confirm that the network is working properly.

2) Verify DNS Settings:

Check the DNS settings on the endpoint to ensure they are correctly configured.
You can use public DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).

3) Flush DNS Cache:

Sometimes, the DNS cache may contain outdated or incorrect information. Flushing the DNS cache can help resolve this.
On Windows, open Command Prompt as an administrator and run the following command: ipconfig /flushdns

4) Test DNS Resolution:

Use the nslookup or ping command to test DNS resolution for the domain you are trying to reach.
For example, open Command Prompt and run: nslookup <domain_name> ping <domain_name>

5) Check DNS Server Status:

If you are using a specific DNS server, check its status to ensure it is operational. You can try switching to a different DNS server to see if it resolves the issue.

And if the issue still persists, please collect the ECT logs from the Endpoint (Laptop) on which you are getting this error and share with your observation.

Please find the steps to collect the ECT logs:

Intel® EMA Configuration Tool (ECT) Logs:

Download the tool from the following link: Intel® EMA Configuration Tool
Installation:

Download and unzip the tool.
Double-click the .msi file and follow the installation prompts.

Run the Tool:
a. Open a command prompt as an administrator (or use Windows PowerShell*).
b. Navigate to the installation folder (default: C:\Program Files (x86)\Intel\EMAConfigTool).
c. Run the following command:
EMAConfigTool.exe --verbose

Best Regards

Thanks for the speed reply Arun. I'm going to work down the troubleshooting list and reply as soon as I can today.

I worked through this list and added my comments under each bullet point or number. After each change I made, I ran EmaAgent on the endpoint as Admin and then clicked Install/Update and then looked on the EMA Server in Managed Endpoints to see if the endpoint would show up. When I note ‘No change’ below, it indicates that I did this process and still didn’t see the endpoint show up in the server.

1) Check Network Connectivity:

Ensure that the endpoint has a stable internet connection.

I used PacketStats.com to evaluate stability and it rated the connection as “Great” showing an average ping of 18.2.

Try to access other websites to confirm that the network is working properly.

CNN.com, Spam.com, and Intel.com all load fine.

2) Verify DNS Settings:

Check the DNS settings on the endpoint to ensure they are correctly configured.

DNS looks good. Points to the router.

You can use public DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).

Done. I manually set my DNS servers to 1.1.1.1 and 8.8.8.8. No change.

3) Flush DNS Cache:

Sometimes, the DNS cache may contain outdated or incorrect information. Flushing the DNS cache can help resolve this. On Windows, open Command Prompt as an administrator and run the following command: ipconfig /flushdns

DNS was flushed. No change.

4) Test DNS Resolution:

Use the nslookup or ping command to test DNS resolution for the domain you are trying to reach. For example, open Command Prompt and run: nslookup <domain_name> ping <domain_name>

Ping and nslookup work on my fqdn. Ping resolves to the server IP and gets an average of 60ms. Nslookup shows that Cloudflare can resolve the domain to the server IP.

5) Check DNS Server Status:

If you are using a specific DNS server, check its status to ensure it is operational. You can try switching to a different DNS server to see if it resolves the issue.

Already switched from the router to Cloudflare and Google. Resolving the fqdn doesn’t seem to be the problem. I will say, however, that I cannot load https://my-fqdn.com in a browser tab. Not sure if that matters.

And if the issue still persists, please collect the ECT logs from the Endpoint (Laptop) on which you are getting this error and share with your observation.
