How did you use tracing to check the current state of a machine’s iptables rules?

In this case I used `perf` utility, but only because the server does not have a proper observability tool.

Take a look at this Netflix presentation, especially on the screenshots of their web interface tool: https://archives.kernel-recipes.org/wp-content/uploads/2025/...

That is a command line tool run over ssh. If you have invented a new way to run command line tools, that’s great (and very possible, writing a service that can fork+exec and map stdio), but it is the equivalent to using ssh. You cannot run commands using traces.
