#DNS To measure the effectiveness of a DoS attack, I'm looking for a tool that can send N DNS requests (to the default resolver or to a configurable name server) at intervals of T (N and T being of course tunable, and better if we can add a jitter to T) and display aggregates such as "X % of the requests were successful". I can program it myself but may be it already exists?

nostr:npub10v743q8jcjxjrzdg7p3z8msqa20v60z4g6z6ehxeprft0fmhxm0svj8uhz Nice graphs but I prefer a simple command-line tool. Also, it seems Jmeter is a stress loader, and I want to measure an actual, present, DoS so I don't want to add load (only the minimum necessary).
