DUMRESP(1)

💖 NAME 💖

dumresp — a dumb DNS responder bestie 🦋 (it's literally in the manual name, she's not even trying to be mysterious)

This one lives in the PowerDNS Authoritative Server manual, section 1, and her whole personality is "I got your packet, here it is back." 👑

---

✨ SYNOPSIS ✨

dumresp LOCAL-ADDRESS LOCAL-PORT NUMBER-OF-PROCESSES [tcp]

---

🌸 DESCRIPTION 🌸

okay so picture this: dumresp sits there on LOCAL-ADDRESS:LOCAL-PORT, accepts DNS packets, and then does the most unserious thing imaginable — she just sends the same query right back at you, except with the QR bit set. that's it. that's the whole job. no cap. 💅

and here's the spicy part: when NUMBER-OF-PROCESSES is set to anything that isn't 1, dumresp will spawn NUMBER-OF-PROCESSES forks and use the SO_REUSEPORT option to bind to the port. so yeah, she's a whole squad, not a solo act. ✨

---

🎀 OPTIONS 🎀

• tcp — whether to listen and accept TCP connections in addition to UDP packets. defaults to false. so if you don't say anything, she's UDP-only, that's her default vibe 🫶
