How can I handle VM migrations without breaking the license

Posted · Add Comment

Licenses for commercial products are bound to a specific System ID, which is a unique host identifier. Unfortunately the System ID, being based on the hardware configuration, is subject to change on Virtual Machines when migrating them across different hosts. This usually breaks the license. In order to avoid this, the latest nProbe (stable v.9.4.210212 and dev v.9.5.210212 or later) and ntopng (stable v.4.2.210212 and dev v.4.3.210212 or later) versions, support a new –vm option that can be used to generate a System ID that has been designed to be resistant to migrations.

nProbe example:

sudo nprobe --version --vm | grep SystemID
39A9B247A2B3B45E

ntopng example:

sudo ntopng -V --vm | grep System
39A9B247A2B3B45E

Please use this System ID when generating the license on the online shop if you install nProbe or ntopng on a VM which is subject to migrations.

If you are not running nProbe, or this option does not work for you, please also read this FAQ.
