I got large udp port range where i need to implement this rule:
If incoming traffic is detected on port $(variable) then execute local linux "command - $(variable)".
The ports are not opened for listening, so there is not possible to see the incoming traffic via netstat, ss, netcat or any other common network monitor tool, tcmdump can see it.
The script must be easy and lightweight.

Hello Sir, I can create shell script which will check UDP traffic on your server and execute mentioned system command. Please message me to discuss more about it. Thank you
Hi there , So let me see if i understood what you're asking for You want a script executs a command on a port ONLY if there is incoming traffic in that port right? What is your distribution?
