How to Force Stop an Unstoppable Node (Image) in PNETLab

Table of Contents

In network simulation environments like PNETLab and EVE-NG, encountering an unresponsive or "unstoppable" node can be frustrating. When a node refuses to shut down through PNETLab web means, it's essential to have alternative methods to regain control and maintain the integrity of your network simulation. Here's a step-by-step guide on how to force stop an unstoppable node in PNETLab:

1. Log in to your PNETLab CLI.
2. Execute the command ps -aux. You can combine this with the grep command to quickly locate the node you want to stop. For example, ps -aux | grep <your node name>.
3. Once you identify the unstoppable node, terminate one by one all related processes by running the command kill <process id>.
4. If the process ID persists, use kill -9 <process id> to forcefully stop it.
5. Return to the PNETLab web and make sure that the node has been successfully stopped.

Below is an example of the above guide:
