When you install a scan node and apply the license file ( sudo dotnet ScanNodeAgent.dll apply-license ), the "Central directory corrupt" error is output. Also, applying the license fails.
The installation was done as root ( su - root ) ¨which causes problems for the Microsoft dotnet package installation. To fix the issue, do the following:
Uninstall the scan node: sudo apt remove --purge fsecure-radar-scan-node-agent Uninstall the dotnet package: dpkg -r packages-microsoft-prod Reinstall the product. Restart the system. Try the installation again but this time do the installation by using sudo instead of root ( su - root ).
The installation should now finish without errors. For more information on installing Radar scan nodes on Linux systems, see our online help documentation.

After Radar license renewal, I'm able to access the Radar portal. However, one or more of my scan nodes show up in an expired state and the scan node has a yellow exclamation mark in the list of scan nodes (Settings >> Scan nodes). Also I'm unable to launch any scans using this particular scan node.
Contact support for further assistance as there might be an issue with your Radar license(s). You can submit a support request from here.

There is an issue with scan nodes not being able to connect to our back end. In short, the "Last seen" and "Engine update" indicators on https://portal.radar.f-secure.com/mmc/settings/scannodes.aspx show a delay of more than 3-4 minutes.
To troubleshoot the scan node connectivity:
Make sure that the F-Secure Radar Scan Node Agent (legacy name= Karhu.Scan.Daemon) service is running. Check this by using Windows Task Manager or Windows Local Service. Make sure that the Windows credentials used to run the F-Secure Radar Scan Node Agent (Karhu.Scan.Daemon) service are able to log in. While logged in with these Windows credentials, run the following command: C:\Program Files (x86)\F-Secure\RadarScanAgent>FSRadarAgent.exe --test
This runs a connectivity test against our Radar Update server backend. There should be no visible problems or errors while the previous test executes.
Ensure that using a browser to access the Security Center portal or https://portal.radar.f-secure.com and https://api.radar.f-secure.com works. Also check if there are any changes in the network configuration or if the connection needs a proxy for outbound traffic.
