activation.code
Plain site code
One line, letters and digits, matching Controller → Help → License Information → export.
Licenses
Nexus does not phone home. The license is a site activation code you hold. Clients store only a hash. Management APIs stay closed until that code is present.
Get a license
Register a site issues a code and stores the organization on this portal.
You still download activation.code for disk images and nexus-license.json for your records.
Planned PC counts are notes only; the software does not cap seats.
Public registration is closed. An operator can issue a site code from the admin portal. You still apply that code in the Controller and on Clients. Planned PC counts are notes only; the software does not cap seats.
activation.code
One line, letters and digits, matching Controller → Help → License Information → export.
nexus-license.json
Organization, optional contact, optional PC count, and the same code. Keep a copy with your records.
How to use it
Minimum 6 letters or digits. Spaces and dashes are ignored. The Controller keeps the plaintext code;
each Client keeps only sha256("nexus-activation-v1:" + code).
Controller
Paste the code, then send it to online clients. Export activation.code from that dialog
when you generalize a lab image.
Client UI
On an unlicensed Client, enter the same code and Activate. Chat and remote management stay closed until then.
Disk image
Place activation.code next to the Client executable, or in the client data directory
(%AppData%\nexus-client on Windows). Clones keep the license and get a new device ID.
Scripted
NEXUS_ACTIVATION_CODE or --activation-code. Unactivated agents stay discoverable; inventory, lock, and files return 403.
After hardware changes, clones keep the code. Reset identity with --reset-identity only when you
need a fresh device ID on the same machine.
Need the files again? Register a site. Ask an operator if you need the files again.
