SSH-keys

• Generate an SSH Key Pair on the local HOST

cd
mkdir -p ~/.ssh
cd ~/.ssh
ssh-keygen -t ed25519
# Type a secure passphrase when asked

chmod 700 ~/.ssh
chmod 600 ~/.ssh/*

# Add the SSH private key to the ssh-agent
eval "$(ssh-agent -s)" && ssh-add ~/.ssh/id_ed25519

• Add the Public Key to a system/sudo user on a potential Ubuntu Server VM

# Local HOST (Ubuntu Desktop VM)
cat ~/.ssh/id_ed25519.pub
# copy the string
# Should start with ssh-ed25519 AAAA... or ssh-rsa AAAA... (if rsa)

# Ubuntu Server VM
echo "pubkey_string" >> ~/.ssh/authorized_keys
# Set permissions
chmod -R go= ~/.ssh

ssh <sudo_user>@<remote_Server_IP>
