Posted by jpluimers on 2024/07/12

Reminder to self to play around with [Wayback/Archive] Tailscale SSH · Tailscale

Tailscale SSH allows Tailscale to manage the authentication and authorization of SSH connections on your tailnet.

Dave Anderson on Twitter: “Cool minor @Tailscale moment: I’m recommissioning a server that got moved from a different network, so all its network config was wrong, and generally I couldn’t get at it over the network, only IPKVM console. But then my `ping` over Tailscale started working?!” / Twitter

Wow, I wrote about Tailscale a few times before, and it is still on my research list, but this is a very compelling reason to use it. [Archive] Dave Anderson on Twitter: “Cool minor @Tailscale moment: I’m recommissioning a server that got moved from a different network, so all its network config was wrong, and generally I couldn’t get at it over the network, only IPKVM console. But then my ping over Tailscale started working?!” / Twitter

I archived the thread so it becomes easier to read: [Wayback/Archive] A readable Thread by @dave_universetf Says Cool minor @Tailscale moment: I’ – UnrollThread.com.

The core are these three tweets:

Turns out, IPv6 autoconfiguration is what happened. Sure, v4 configuration was entirely wrong (it was trying to connect to wifi, via a wifi dongle that was no longer installed, and wanted to talk to a DNS server that doesn’t exist any more), but eno1 had a cable plugged in!
The server noticed IPv6 router advertisements, went “I’ll have some of that”, and got global IPv6 connectivity automagically. IPv4 and DNS were still down though, so all it had at this point is the ability to send/receive IPv6 packets.
So, how did Tailscale get from there to a working setup? It still needs to contact https://t.co/hEs4S8qvTw to get a network map, and still needs to talk to DERP servers to get p2p tunnels working outside the LAN. Enter bootstrap DNS!

It means I have to re-read Source: Some links on Tailscale / Wiregard, especially the [Wayback] How Tailscale works · Tailscale bit, then decide how I want to organise my infrastructure to run parts under Tailscale (I have the impression it is a peer based set-up, not router based).

Then I have to read [Wayback/Archive] IPv4, IPv6, and a sudden change in attitude – apenwarr of which the conclusion is this:

IP mobility is what we do, in a small way, with Tailscale’s WireGuard connections. We try all your Internet links, IPv4 and IPv6, UDP and TCP, relayed and peer-to-peer. We made mobile IP a real thing, if only on your private network for now. And what do you know, the math works. Tailscale’s use of WireGuard with two networks is more reliable than with one network.

Finally I need to not just read it, but understand all it (:

Or maybe I should ask Kris, as I got here through:

Wake-on LAN over tailscale VPN

Posted by jpluimers on 2022/03/22

Hey macOS desktop in the basement, thanks for going to sleep while I was in the middle of typing at you via SSH.

Maybe that should be a signal not to sleep, eh?

$ sudo wakeonlan ac:87:a3:19:7e:81
Sending magic packet to 255.255.255.255:9 with

Well, at least that works.

Some links on Wireguard as DHCP clients were not supported back then yet

Posted by jpluimers on 2021/11/12

Wireguard seems more light-weignt and secure than OpenVPN and IPsec. So I’m anxious to know how it is supposed to work for road warriors that often depend on receiving DHCP addresses into the network of the VPN server.

Some links that hopefully get me started to install a Wireguard VPN server and provide services to road warrior clients.

First the Twitter thread that got me investigating:

Then some links I found:
