Tailcat: Tailscale Without Tailscale, by Tailscale
TL;DR
Tailcat is a new open-source tool that allows users to utilize Tailscale's data plane without relying on its control plane, enabling secure connections using WireGuard encryption. It combines a Go package and CLI tool for bidirectional data transfer, similar to netcat but with enhanced capabilities.
✦ Why It Matters
Explore Tailcat today to implement secure, independent networking solutions without relying on Tailscale's control plane.
Key Takeaways
- Use tailcat for secure data transfer without IP addresses or logins.
- Run your own DERP server to avoid bandwidth limitations.
- Leverage tailcat for quick connections between untrusted systems.
- Explore community contributions to enhance tailcat's functionality.
How It Works
Tailcat operates by generating a keypair and selecting a DERP server for connections. It creates a unique address for the server, which clients use to connect.
The client sends a message to the server's public key to establish a connection, allowing data transfer over WireGuard. NAT traversal is automatically handled, enabling direct connections when possible, or falling back to DERP relays when necessary.
