ssh begin.fish

A fishing pond played over SSH. Everyone who connects is on the same water.

begin.fish is a Cloudflare Tunnel. With cloudflared installed once
(brew install cloudflared, or https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/),
give ssh this, in ~/.ssh/config:

  Host begin.fish
    ProxyCommand cloudflared access ssh --hostname %h

then, from any terminal:

  ssh begin.fish

Without cloudflared, the bridge works too:  curl -fsSL https://pond.begin.fish/install | sh

begin.fish reaches the pond at the tunnel's end, which may not be the one at ssh.fish, bash.fish, beginbot.fish.
ssh will ask about its host key once, as with any new host.
