Understanding user intent is key. The high search volume for this phrase stems from several legitimate and illegitimate scenarios.
If you own a legacy RSM-B V5 license:
| Command | Description |
|---------|-------------|
| rsmb‑activate | Launch interactive activation (online). |
| rsmb‑activate --offline-request > req.txt | Generate offline activation request. |
| rsmb‑activate --offline-apply req.txt | Apply an offline activation file. |
| rsmb‑status --license | Show current license details. |
| rsmb‑license‑reset | Remove existing license (useful for re‑install). |
| systemctl restart rsmb | Restart service after (re)activation (Linux). |
| Symptom | Likely Cause | Fix |
|---------|--------------|-----|
| “Invalid key” | • Typos (missing hyphen, extra space).
• Using a key for a different product/version. | Double‑check the string; verify it’s for RSMB v6. |
| “Unable to contact license server” | • No internet access.
• Corporate firewall blocking license.rsmb.com.
• Proxy not configured. | Ensure outbound HTTPS (port 443) is allowed; set proxy env vars (HTTPS_PROXY). |

| License file not found after reboot | The license file is stored in a non‑persistent location (e.g., /tmp). | Confirm the file resides in the user’s home directory or the system‑wide /etc/rsmb folder. |
| Activation fails on Linux with “permission denied” | Running the CLI without sufficient privileges. | Use sudo rsmb‑activate or ensure the user owns the .rsmb folder. |
| Upgrade to v6.2 blocked | Existing key is tied to v5. | Use the upgrade workflow in the portal; you’ll receive a new v6‑compatible key. |
If none of the above solves the problem, contact RSMB Support:
