How to generate and add an SSH key on Linux

What you’ll need

A Hivenet account with Compute credits ready
A Debian-, Ubuntu-, Fedora-, or Arch-based distro (others work too)
OpenSSH client (ssh) installed
A terminal emulator

Step 1 – Create your SSH key pair

ssh-keygen -t ed25519

Accept the default path (/home/<you>/.ssh/id_ed25519).
Add a passphrase for extra security.

Password managers such as 1Password, Bitwarden, and KeePassXC can generate and store SSH keys automatically. If you already rely on one, it’s an easy alternative to the ssh-keygen command.

Step 2 – Find your key files

Open the folder in your file manager:

xdg-open ~/.ssh

—or browse there manually (Home → .ssh). You should see:

id_ed25519 (private)
id_ed25519.pub (public)

Step 3 – Add your public key to Hivenet

Copy the public key to your clipboard:
cat ~/.ssh/id_ed25519.pub | xclip -selection clipboard
_(If _xclipisn’t installed, just open the file in a text editor and copy.)
In Compute with Hivenet, paste the key into SSH key when you spin up an instance.

Share only the .pub key. Keep the private key private.

Step 4 – (Optional) add a quick SSH config

Create or edit ~/.ssh/config:

Host hivenet
    HostName YOUR_SSH_HOST
    User YOUR_SSH_USER
    IdentityFile ~/.ssh/id_ed25519
    Port 22

Replace YOUR_SSH_HOST and YOUR_SSH_USER with the values in the instance’s SSH connection details, and use your matching private key. Include any additional settings supplied by the console. See SSH configuration and host verification. Connect with:

ssh hivenet

Troubleshooting

Message	Likely cause & fix
Permission denied (publickey)	Wrong key or the public key isn’t on the instance. Re-check the key path or re-add the key.
Connection timed out	Check the console’s connection details and outbound port 22. Try `ssh -v hivenet` for details.
ssh: command not found	Install the OpenSSH client package (`install openssh-client`, `sudo dnf install openssh-clients`, etc.).
