Packet capture not working on kubernetes

[abasitt]

I Installed the default helm installation of packet streamer as daemonset on kubernetes but I am not able to capture any traffic. The sensor shows the traffic capture count, but the receiver side the the logs shows 0B and also the size of the /tmp/dump file never increase. If i enable to save packets at the sensor side, again I don't see the size of the /tmp/dump file increasing.

To Reproduce kind create cluster --config config.yaml

three node (two workers) cluster config

kind: Cluster apiVersion: kind.x-k8s.io/v1alpha4 name: cluster1 nodes:

• role: control-plane image: kindest/node:v1.23.6@sha256:b1fa224cc6c7ff32455e0b1fd9cbfd3d3bc87ecaa8fcb06961ed1afb3db0f9ae

Expected behavior I should be seeing the packet arriving at the receiver and the size of the /tmp/dump should increase

Additional context I have tried the similar installation on kubeadm Calico cluster but facing the same issue.
