Tailscale open sources Tailcat, a netcat-style tool built on Tailscale's data plane
- Sources: tailscale/tailcat, HN 49452990
- Summary: Tailcat uses Tailscale's data plane without its control plane. It provides WireGuard-encrypted point-to-point transfer, port forwarding, a SOCKS5 proxy, and an exit node. WireGuard, magicsock, and a gVisor netstack all run in userspace.
- Why it matters: It gives an encrypted transfer and forwarding path between two machines without a Tailscale account and without root.
