At least after manually editing the setting through sysctl directly and adding the dietpi-tailscale.conf file through the -e flag the system gets IPv6 again through RA. Now I just need Tailscale to be running as well.

you are running Docker in that device?

Zelaf · 19 September 2023 12:54

Yes, hence all the veths. Do you think the Docker networks are somehow causing issues with tailscale?

trendy · 20 September 2023 07:48

It seems that Tailscale is trying to reconfigure many times after the network changes. Could be that it starts early in the boot process and then some docker configuration changes the network.
Are you able to resolve after all booting process is finished?

Joulinar · 20 September 2023 07:54

I know docker is causing issues for WireGuard and OpenVPN because Docker sets iptables policy for the FORWARD chain to DROP. Maybe it’s doing similar for Tailscale

Zelaf · 26 September 2023 08:34

Sorry for the late reply, got lost in Starfield.

All the things I’ve tried so far has been after rebooting. I try to reboot as little as possible so no, it doesn’t get resolved after rebooting and restarting the services sadly.

Interesting. Seems like on this device is it only an issue. Have been working just fine before. I’ll see if I can investigate that a bit.

Zelaf · 27 September 2023 18:00

Alright so I had some time over to check the things and did some unrelated configuration on the Tailscale admin panel and I noticed that the Pi is shown as connected, I went in and checked on the Pi and sure enough, tailscale is up and running and connected to the tailnet. However I still can’t get the Tailscale config software to connect to tailscaled. I’m glad it works at least.

I think when I configured tailscale while running the daemon manually in a separate bash instance and configured it that way the settings must’ve gotten saved and gets connected now. It’s a good step forward for my network setup at least. The logs show a similar output to before.

I’m guessing there’s something wrong with how Tailscaled is setup so the client can’t interface with the sock in some way. I can’t seem to find the sock anywhere on the system when doing a search using sudo find / -type f -name "tailscaled.sock" so it must not be creating it for some reason.

I’ll paste the systemd files for tailscale. I have not modified these to be clear.

}

tailscaled.sock

Apparently the tailscale sock exists anyways. Must be doing something wrong with find. I’ll continue to test some things.

trendy · 28 September 2023 07:34

Did you do a ss -tunlp | grep 41641 ? This will show you if the socket is open.
