Introduction

With a RADAR DEPLOY owned node subscription, you’re able to be in full control of your blockchain nodes. Using secure shell (ssh) connections, you can connect directly to your node and make any configuration changes you wish to the underlying system, stop and restart services, or even install your own custom add-ons and applications directly on the node itself.

Enabling

Every DEPLOY owned node subscription automatically comes with SSHd pre-installed and configured.

Connecting

The SSH Access tab on the Connect to your node modal

macOS, Linux, Unix

Your SSH username and password are available in the Connect to your node modal on the node details page, simply copy the SSH command from the SSH Access tab into your terminal and enter the provided password.

Windows

Using a graphical SSH client like PuTTY, simply copy the hostname, username, and password from the SSH Access tab of the Connect to your node modal. The modal displays the SSH connection information in the format <ssh username>@<ssh hostname>.

Alternatively, on Windows 10, you can use the Windows Subsystem for Linux to run a linux distribution and follow the directions above.

Example Use Cases

If you are running a specialized service that requires a specific configuration of a chain daemon or are looking to add explicit initial peers to your chain daemon, connecting via SSH and manually adjusting the chain daemon configuration file (ex: /etc/bitcoin/bitcoind.conf for bitcoind nodes) would be easy to accomplish.

You can also chose to run additional applications on your DEPLOY node to perform additional tasks like observing chain state, querying chain data, or performing blockchain transactions. You can simply copy or download any binaries onto your DEPLOY owned node and run them the same as any other linux-based server.

Disabling

You are unable to disable SSH access to your DEPLOY owned node via the DEPLOY management application. However, it is possible to make an initial connection to the node via SSH and then disable the SSHd service. Warning: disabling SSHd will result in your node becoming inaccessible via SSH. RADAR cannot assist in re-enabling SSHd after it is disabled.
