Salut Stephane, https://meetings.ripe.net/ripe-43/presentations/ripe43-dnr-distel/sld001.html
This is the idea.Prepare file to replay with fuzzer or use real world malformed queries. ;-)
The separate tools are still all available. I could dig into my archive and see if I still have the scripts and the patches to tcpreplay. If I remember correctly the changes were to replay UDP and to re-compute checksums.

I maintain an experimental authoritative DNS server and I would like to test its robustness. dnsperf and flamethrower are great to test its performance, zonemaster and dnsviz are perfect to test its correctness in face of legal input but I would like to see how it reacts to *illegal*, malformed input. (An example of such input is <https://lists.dns-oarc.net/pipermail/dns-operations/2022-May/021657.html>.) Since most DNS libraries are made to prevent the programmer for issuing illegal DNS requests, it is not obvious to write such a test. Are you aware of libraries / programs / frameworks to exercice, in a hard way, the robustness of a server? _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations
