I tried to capture the traffic but I got these error
I can’t understand because by defaut by account is root. why I have no permition?

root@vyos:/ddos# tcpdump -i eth0 ‘dst 100.64.52.10 and (dst port 161 or 162)’ -w wireshark.pcap
bash: /usr/bin/tcpdump: Operation not permitted

You have to setup proper capabilities

set container name FOO cap-add xxx

And VyOS doesn’t use docker, it uses podman
