SSH access - LayerRail Docs

LayerRail uses SSH public keys for VM access. You add the public key during VM creation and keep the private key on your machine.

Generate a key

If you do not already have an SSH key, create one locally:

ssh-keygen -t ed25519 -C "you@example.com"

Show the public key:

cat ~/.ssh/id_ed25519.pub

Paste that public key into the VM creation form.

ssh <username>@<public-ip>

For Ubuntu images, the default user is usually:

ssh ubuntu@<public-ip>

Problem	Check
Permission denied	Confirm you are using the private key that matches the public key on the VM.
Connection timed out	Confirm the VM is running and port `22` is allowed by the firewall.
Wrong username	Check the username field on the VM creation page.
Key format rejected	Use an OpenSSH public key, not a private key or `.ppk` file.

Never paste your private SSH key into LayerRail or a support ticket.
