The DuniterNodeManager is a lightweight, cross-platform application for interacting with a Duniter-v2 node and oracle installed on a remote server. It provides a minimalistic interface for editing node and oracle configurations, starting or stopping the node and oracle, and checking their logs.
Each command initiates a single SSH connection, which closes immediately after execution, ensuring no persistent connections. The application supports both password-based and SSH key authentication, with SSH keys recommended for security.
DuniterNodeManager requires the node to be installed on the server and a list of commands (see [README](https://github.com/bgallois/DuniterNodeManager/blob/master/README.md)) to be cleared from the `sudo` password. The method is left to the server administrator based on the level of security they want to enforce.
Oracle interaction will only work with the next version of the Oracle [client](https://git.duniter.org/nodes/rust/duniter-v2s/-/merge_requests/296).
You can download the latest release of the Duniter Node Manager from the [releases page](https://github.com/bgallois/DuniterNodeManager/releases/latest) (available in EXE, AppImage, and App formats).

So how can you follow logs in realtime without stable ssh connection?
Why this approach?
* * *
Can you activate issues on you github repo?
If I click on any button with no configurations, the app crash:
```auto

```
Buttons should be disabled if no configuration set.

I think some icons are not found:
* * *
It automaticly found all my ssh keys in `~/.ssh` 👍
* * *
Unable to find my duniter mirror node:
Cannot be used with Docker installation?
~~For systemd installation, require a root ssh access to be able to manipulate systemd?~~ → RTFM
* * *
Good project anyway !

There is no real-time log; it just pulls the log each time we request it. There is no icon that is entirely emojis, I will probably export the font with the executable next release to avoid any problem.
There is no intention of supporting Docker; this will only be for native installation with systemd.
