In this article you will find the most common reasons behind license related problems in the form of a checklist.
You can start your troubleshooting by going through this checklist in any order you see fit:
-
Use the latest available UMS version and OS version. You can download the most recent version from https://www.igel.com/software-downloads/.
-
Check if NTP is set, and if time/date is correct on the devices. For more information, see Time and Date and (12.4-en) Time and Date in IGEL OS 12 .
-
Check if time/date differs on hardware level. Check the BIOS. For more information, please refer to the corresponding documentation of your hardware vendor.
-
Check if the MAC address and unit ID are the same. In case they are not, you can restore the MAC address by running the command
get_unit_id -r -fin a terminal and rebooting the system afterwards. -
Check if the license deployment is set to automatic. For more information, see How to Enable Automatic License Deployment in IGEL.
-
Check the communication ports. For more information, see (12.04.120) IGEL UMS Communication Ports.
-
Check for BIOS updates.
-
Try deploying the
licfile locally. For more information, see Manual License Deployment for IGEL OS without UMS . -
Delete all local licenses. For more information, see How To Remove an IGEL License Completely .
-
On IGEL OS 11, check the output of
rm_ping_for_licensein Local Terminal. -
In case you use ALD via ALD Token, it might make sense to delete the ALD token and create a new one, especially when you had a renewal and the expiration date doesn't get updated in your UMS. For more information see Setting up Automatic License Deployment (ALD) with ALD Token.
