Tailscale setup

Setting up Tailscale is remarkably simple because it handles the complex networking (like NAT traversal) for you. Here is the compact guide to getting your private mesh network running.

1. Create an Account

Before installing the software, you need a coordination server to manage your nodes.

Go to tailscale.com and sign up.
You can use Single Sign-On (SSO) through Google, Microsoft, GitHub, or Apple.

2. Install on Your Devices

You need at least two devices to see the “magic” happen.

For Desktop & Mobile:

Windows/macOS: Download the installer from the website, run it, and log in.
iOS/Android: Search for “Tailscale” in your app store, install, and sign in.

For Linux (The Quick Way): Run the official installation script:

curl -fsSL https://tailscale.com/install.sh | sh

Then, bring the interface up:

sudo tailscale up

Follow the URL provided in the terminal to authenticate.

3. Connect and Verify

Once logged in, your devices are part of your Tailnet.

Check the Admin Console: Visit the Tailscale Machines page. You’ll see all connected devices and their unique 100.x.y.z IP addresses.
Test the Connection: From “Device A,” try to ping the Tailscale IP of “Device B”:
```
ping 100.x.y.z
```

4. Essential Quick Commands (Linux/CLI)

Command	Action
`tailscale status`	See other devices on your network.
`tailscale ip -4`	Show your current device’s Tailscale IP.
`tailscale logout`	Disconnect the device from the Tailnet.
`tailscale up --exit-node=<ip>`	Route all your traffic through a specific node (VPN style).
