Hey, I'm reaching out to you with a question.

I run a second Unraid server for data backup:

A = My main Unraid server
B = My Unraid backup server

Server B is located in a different location. Both servers have Tailscale installed and connected to the Tailscale network. I can connect to the Unraid web interface of Server B from all clients.

For backing up my data, I use the Rsync script by Mgutt. This involves writing data from A to B using SSH with rsync. The SSH certificates have been exchanged, so no password input is required.

The Tailscale SSH service is enabled on Server B.

However, when I try to connect to Server B from Server A via SSH (on the Tailscale network) in the Bash shell, I always get the Tailscale Check Mode displayed. To proceed, I have to authenticate through a browser link.

Naturally, this prevents my weekly Rsync backup from working, as the SSH connection requires re-authentication every 12 hours (according to the Tailscale Wiki SSH Check Mode).

My question is: How can I change the SSH connection from Check Mode to Accept Mode within Tailscale on Unraid?"

Thank you in advance for your help.

Regards,

Thomas

Hey, my question has been resolved.

To set up Accept Mode, nothing needs to be done in Unraid (other than enabling SSH within the Tailscale plugin there). Instead, you need to go to the Tailscale website (Machine Overview), and change the entry for SSH from "check" to "accept" under the Access Controls menu at the top.

Best,

Thomas
