What is Device Recognition?
Credential-free Device Recognition or CDR is a feature that aims to do very much with very little. Building upon existing functionality such as Asset Radar and IP scanning, Lansweeper applies machine learning techniques and big data to enrich assets. Credential-free Device Recognition allows Lansweeper to more accurately determine the asset type of certain devices, and to add additional information that could previously not be retrieved without credentials. Information such as the manufacturer, model and operating system. This means that assets that were previously generically identified can now be enriched.
This article details how this feature works, how to enable it and what the pitfalls are.
How Credential-free Device Recognition works
How to enable Credential-free Device Recognition
Configuration\Server Options
. In the Credential-free Device Recognition section, click Enable Credential-free Device Recognition on this server
.- The Lansweeper Server service is operational.
- The scanning server can reach the endpoint URLs, which you can find listed at the bottom of this article.
- Whether your license allows the usage of this feature.
Click Ok
to enable CDR once the requirements checks are passed.
Troubleshooting
This section of the article aims to address what to do if Credential-free Device Recognition (CDR) cannot be enabled, or is non-functional due to network connectivity issues.
Make sure the Lansweeper Server service is running
The scanning server you have selected as your recognition server must be operational. Open services.msc
on the relevant Lansweeper server and check that the Lansweeper Server service is running. If it is not, you can refer to this article.
Make sure your Lansweeper server can connect to the internet
Credential-free Device Recognition requires your scanning server to be able to access the internet either directly or via a proxy. You may receive the error below in your web console. This may be caused by one of the following:
- The scanning server you've enabled CDR on has no internet access.
- The scanning server you've enabled CDR on requires proxy configuration.
- Your firewall is blocking access to the URLs used by CDR.
Internet Access
Connect to your Lansweeper server directly and test using a browser whether you can connect to the internet, e.g. www.google.com
. If this fails, investigate and resolve your server's connection issue.
Proxy server
If your Lansweeper server connects to the internet via a proxy, make sure to add your proxy details under Configuration\Server Options
. Make sure these details are correct and that your proxy server is currently available. Do not fill in this configuration section if you do not use a proxy server.
Firewall
Your firewall or proxy may block certain outbound connections, in which case you'll need to whitelist the endpoints used by CDR. Make sure your Lansweeper service can connect to the URLs below. In a practical sense, this may mean for example allowing outbound traffic targeting port 443 on recognition.lansweeper.com. The specifics will differ based on the firewall or proxy system in use.
