OpenDNS Diagnostic Tool: What to Provide Support When Asked
Support will often ask for the results of our diagnostic tool, especially when troubleshooting difficult issues. The steps to using the tool are straightforward, but it's very important to send the link that's generated by the tool, rather than a screenshot of the information or having the information pasted.
The tool can be found here:
Microsoft Windows : http://www.opendns.com/download/windows/diagnostic
Mac OS X : http://www.opendns.com/download/mac/diagnostic
Linux: No tool, see Terminal instructions here
Running the Cisco AnyConnect Umbrella Roaming Module? This is a different diagnostic test! To run, follow these instructions:
Windows: Run the diagnostic executable from: C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\UmbrellaDiagnostic.exe
Mac OS X: Open up the terminal and run
tail -n 15000 /var/log/system.log | egrep -i "acumbrella|kernel|launchd|vpn|dns|configd|racoon|umbrella"
Also, attach a zipped copy of the "/opt/cisco/anyconnect/umbrella/data/beacon-logs/service' folder.
Instructions for use of the Diagnostic Tool on all three operating system types is below
Microsoft Windows
When you first run the tool, you'll be asked for account information, ticket information and a domain to test with. This information is all optional, but if there is a specific domain you are having trouble accessing, please include it the Domain to test field:
Click Run tests. The tests should only take a few moments to complete and at the bottom of the diagnostic output there will be a link displayed. This is the link you'll want to send to the OpenDNS Support team
In the example above, OpenDNS would need the link "http://diagnostic.opendns.com/d/5407505022713856". Please do not send the exact link above; however, send the link that appears in your diagnostic result.
In order to protect your information and that of our other customers diagnostic information uploaded to OpenDNS is only accessible to OpenDNS employees authenticated through our systems. You won't be able to view the diagnostic results but the support team will be able to see them if you provide the URL of the results.
Only the link itself is needed, please click on the link then copy and paste the URL results into your ticket. In the worst case scenario, if you can't copy and paste the link, feel free to send us a screenshot of the link.
Do not log in to the link - this is for OpenDNS Staff to log in and access the results. You will not have access to this even with your OpenDNS account.
If the Diagnostic does not run, provide the results of the following command prompt commands:
