"Tailscale without Tailscale, by Tailscale"
Tailcat
Tailcat is a remix of Tailscale open source pieces to act like
netcat
, but over Tailscale's data plane,
without Tailscale's control plane. Tailscale's data plane (
magicsock
,
internally) gives you point-to-point WireGuard®-encrypted tunnels between two
machines with DERP as the NAT-hole-punching communication side channel and the
ultimate relay-of-last-resort if NAT traversal fails. Instead of using the
Tailscale control plane, all
tailcat
connection metadata is exchanged out of
band, however you want.
The
tailcat
CLI (in
cmd/tailcat
) is built on the
tailcat
Go library
(importable as
github.com/tailscale/tailcat
).
Whether you use
tailcat
as a CLI tool or library, one side runs a
tailcat
server (listener) and gets back a short connect (EN)
