dumpcap \
  -i ens3 \
  -w /root/hardware-device_working.dcap
dumpcap \
  -i tinc.test \
  -w /root/tinc-device_working.dcap
```

and for the not working experiment

```
dumpcap \
  -i ens3 \
  -w /root/hardware-device_not-working.dcap
dumpcap \
  -i tinc.test \
  -w /root/tinc-device_not-working.dcap
```

logs
