The following is all based on the excellent hyperssh NodeJs package by @mafintosh.
sudo apt-get install openssh-server
git clone https://github.com/mafintosh/hyperssh.git
cd hyperssh
npm install
npm link
(Copied from the Hyperssh README)
On a server or some laptop with ssh-server running run
hyperssh-server
This will print out the ssh fingerprint and start announcing the server on the Hyperswarm network under this fingerprint.
To connect to the server on another computer simply pass in the fingerprint and the user you want to connect as to hyperssh
hyperssh ssh-ed25519 AAAA.... maf
