What you’ll need

  • A Compute instance with your SSH public key uploaded
  • Windows 10 or later
  • Windows Terminal / PowerShell (OpenSSH)

​
OpenSSH via Windows Terminal

​
Step 1 – Check OpenSSH is installed

Open PowerShell and run: 
ssh -V
You should see an OpenSSH version. If not, enable it:
  1. Settings → Apps → Optional features
  2. Add a feature → OpenSSH Client

​
Step 2 – Create or convert your key

  1. If you don’t have a key yet
    • Open PuTTYgen and click Generate.
    • Move your mouse until the progress bar fills.
    • Make sure you do the key Conversions to**OpenSSH key **
    • Import or load the new key converted.
    • Click Save public key (keeps the .pub extension).
    • Click Save private key (you’ll get a .ppk file).
    • Upload the public key in the Compute dashboard.
  2. If you already have an OpenSSH key
    • In PuTTYgen click Load, pick your existing id_ed25519 (or id_rsa).
    • Click Save private key to export it as .ppk.
PuTTYgen can also create a fresh key pair if you don’t have one yet.

​
Step 3 – Create a config entry (optional)

In C:\Users\<you>\.ssh\config, add: 
Host hivenet HostName <instance-id>.ssh.hivecompute.ai User ubuntu IdentityFile ~/.ssh/id_ed25519 ProxyCommand ssh bastion@ssh.hivecompute.ai %h
Save, then simply: 
ssh hivenet

​
Step 4 – Connect manually

Without a config file, run: 
ssh -i ~/.ssh/id_ed25519 ubuntu@<instance-id>.ssh.hivecompute.ai
Replace <instance-id> with your actual ID.

​
Troubleshooting OpenSSH

  • Permission denied → Wrong key or not uploaded
  • Connection timed out → Check internet/firewall
  • Unknown host → Typo in instance ID

​
Common PuTTY pitfalls

  • Server unexpectedly closed connection → Wrong port or host name
  • No supported authentication methods available → Wrong key format
  • Support modern encryption and OpenSSH compatible formats
