I'm running Zeek on a Docker container (from image Zeekurity) in standalone mode and I'm trying to disable checksum offloading for my network interface, but then this happens:
root@0787148fac96:/usr/local/zeek# ethtool --offload eth0 rx off tx off
netlink error: Operation not permitted`
I really can't understand why.
Zeek version is 2.7.1, container's OS is Linux 11, Docker version is 20.10.17 running on Ubuntu version 22.04 LTS 64 bit
