The “Connection Refused” error when trying to SSH into your HDP 2.5 VirtualBox setup is a common issue that usually relates to network settings or authentication. Here are some steps to try: Ensure your VirtualBox network settings are correctly configured—NAT with port forwarding enabled so the SSH port (usually 22) is reachable from your host machine. If port forwarding is set but SSH still refuses connection, try switching the network mode to Bridged Adapter temporarily to check connectivity. Another important step is to reset the root password inside the VM. You can do this by pressing Alt+F5 at the splash screen to open a terminal, then run the command passwd to set a new root password. Use this new password to login via SSH. Make sure the SSH service is running inside the VM. You can check this by running sudo service ssh status or systemctl status sshd.
