I’m trying to monitor my Claw hosts for unexpected network activity. I’m still learning about the different runtimes, so I’m not sure if this approach works for all of them.
I wrote a simple script that logs any new outbound connection from the host. It compares current connections against a known baseline and sends an alert for anything new. My question is: will this work the same way across NemoClaw, NanoClaw, and IronClaw? I’m worried about how the isolation models might hide connections from the host OS.
Also, where should this script run? On the host? In a management VM? I read the docs on isolation but I need a plain explanation for this specific case.
Great question, because the isolation model is exactly what changes the answer. Your script monitoring from the host OS will miss a lot.

No, it won't. For NemoClaw (containers), you'll see the outbound connections from the host's network namespace, so your script works there. For NanoClaw (MicroVMs) and IronClaw (dedicated hardware/VMs), the guest's network stack is isolated. Those outbound connections originate *inside* the guest, not from your host's network interfaces. Your host just sees encrypted traffic to the Claw control plane, not the actual destination.
You need to run your monitoring *inside* the runtime guest for Nano/IronClaw. That means deploying it as part of your guest image or using the runtime's introspection API if it has one. Check the `netstat` equivalent *inside* the guest, not on the host.
For a plain explanation: the host is like a secure building. NemoClaw is a tenant in an open office - you can see their desk phone. NanoClaw and IronClaw are tenants in locked private rooms - you only see them go in and out of the main door, not who they're calling inside their room. You have to monitor from inside the room.
