IATRT Secure Access
Setup help for Windows, Linux, and QNAP.
Use this page when an IATRT technician asks you to connect a device for remote support. You may be given either a setup link, a one-time auth key, or a public SSH key to install. If the wording on your device differs slightly, use the closest matching option.
Before you start
- Make sure the device has internet access.
- Have the IATRT setup message ready.
- Use the exact account, setup link, or one-time key supplied by IATRT.
- If your device is company-managed, make sure you are allowed to install software first.
What IATRT may send you
- A setup link for browser-based sign-in
- A one-time auth key for guided enrollment
- A support public SSH key for Linux or QNAP
- A short hostname or device label to use
Windows
- Install the Tailscale client from the official Windows installer.
- Open Tailscale after install.
- If you were given a setup link, open it and follow the prompts.
- If you were given a one-time key, use the exact onboarding method your technician supplied.
- Wait until the client shows that the device is connected, then tell IATRT the machine is online.
Useful checks:
- The app should be running in the system tray.
- The device name should match what your technician expects.
- You should not need to create your own separate account unless IATRT explicitly told you to.

Linux
- Install Tailscale using the method appropriate for your distribution.
- Bring the client up using the setup details provided by IATRT.
- If a one-time auth key was supplied, use it exactly as provided.
- If a login server value was supplied, use that exact value rather than the default service.
- Confirm the device is connected, then send the hostname back to IATRT.
Typical install command:
curl -fsSL https://tailscale.com/install.sh | sh
Typical verification commands:
tailscale status
tailscale ip

QNAP
- Open App Center on the NAS.
- Install Tailscale if it is available for your model.
- Open the app and follow the setup link or auth flow supplied by IATRT.
- Leave the NAS online until your technician confirms it is visible.
If Tailscale is not available in App Center:
- Tell IATRT the exact QNAP model and firmware version.
- Do not install random third-party packages unless your technician tells you to.

QNAP SSH key install
If IATRT sent you a public support key for SSH access, install that key only for the account agreed with your technician.
- Enable SSH in QNAP if your technician told you to do so.
- Log in to the NAS locally or from your normal approved location.
- Open the target account's
~/.ssh/authorized_keysfile. - Paste the IATRT public key on its own line and save the file.
- Do not paste private keys, passwords, or recovery codes into chat or email.
Troubleshooting
- Client installed but not connected: restart the client, then retry the same setup link or auth flow.
- Wrong account prompt: stop and ask IATRT which account or login server should be used.
- QNAP app missing: send the NAS model and firmware version to IATRT.
- SSH key rejected: confirm you pasted the full public key on one line into
authorized_keys. - Still stuck: send IATRT a screenshot of the exact error message.
