Allow remote ssh connection

[jeluard]

SSH access should be enabled, based on default GitHub's user ssh keys.

Rely on default GithHub public key, if any. Only allow PK connection.

Pseudo manual steps

NOTE: does not work yet, blocked by missing TCP port redirection

Create a playground session, open a terminal

# Sudo password is 'password'

# Add PK
curl https://github.com/jeluard.keys | tee -a ~/.ssh/authorized_keys

# Start ssh
sudo apt update
sudo apt install ssh
sudo service ssh start

Then connect from remote

ssh jeluard.playground.substrate.dev
