SOCKET_...AMEINFO(1p)

💖 NAME 💖

okay so <pink>socket_getnameinfo</pink> — it's a command-line tool that wraps up the <purple>getnameinfo(3)</purple> resolver, bestie. that's the whole vibe ✨

---

🌸 SYNOPSIS 🌸

socket_getnameinfo [options...] address port

---

🦋 DESCRIPTION 🦋

so basically this tool is a cute lil convenient command-line wrapper around the <purple>getnameinfo(3)</purple> resolver function. it does one single reverse lookup and turns an address plus a port number into their host and service names. periodt 💅

and like, why do you care? because it's mainly useful when you're debugging name resolution problems 🕵️♀️ — it lets you peek directly at what <purple>getnameinfo(3)</purple> is doing itself, totally outside of any real program that's trying to use it. no middleman, no extra chaos, just the raw behaviour. iconic honestly 🎀

---

✨ OPTIONS ✨

• --address, -A ADDR — the numerical form of the address you wanna look up. if you don't pass it, it'll just use the first positional argument instead 🫶
• --port, -P PORT — the port number you wanna look up. if you don't pass it, it'll use the second positional argument 💖
• --dgram — sets the <purple>NI_DGRAM</purple> flag, so it looks up a <purple>SOCK_DGRAM</purple> (udp) port allocation instead of <purple>SOCK_STREAM</purple> (tcp). lowkey important, don't skip it 🔥
• --help — shows a help summary and dips out ✌️

---

📝 NOTE 📝

upstream, this script is actually called <pink>getnameinfo</pink> — but on Debian it got renamed. so if you're out here looking for getnameinfo and it's giving nothing, that's why bestie 😭
