💅 ssdp-scan — a General Commands Manual moment

okay so bestie, welcome to ssdp-scan(1) — yes she's a real manual page, yes she's from the General Commands Manual, and yes we're gonna get through this together 🫶

✨ NAME ✨

ssdp-scan — scan for SSDP capable devices on attached networks 🦋

---

🌸 SYNOPSIS 🌸

ssdp-scan [-h] [-l LEVEL] [-t SEC]

---

💖 DESCRIPTION 💖

ssdp-scan is a tool for scanning for Simple Service Discovery Protocol (SSDP) capable devices on attached networks. That's the whole vibe 💅

What it literally does: it sends M-SEARCH * to 239.255.255.250 to continuously update a list of SSDP hosts. Constantly. Relentlessly. Main character energy, honestly 🔥

---

🎀 OPTIONS 🎀

the following command line options are available, bestie — all of them, no skips:

• -h — show program help text. that's it, that's the flag 💁‍♀️
• -l LEVEL — set log level to one of the following, default notice:
  • none — disable all logging
  • error — error conditions
  • warning — warning conditions
  • notice — normal but significant condition (default) ⭐
  • info — informational
  • debug — debug-level messages

and then, right here on the page: timeout and exit after SEC seconds. (yeah she's listed under -l, but go off, the -t SEC from the synopsis is clearly who she's about 😭)

• [IFACE] — by default ssdp-scan runs on all IPv4 capable interfaces, except loopback. If interface names are given as arguments, ssdp-scan will run only on them. pick your faves 🎀

🔥 NOTES 🔥

ssdp-scan is very impatient. the way that it just cannot sit still 🧚 in order to scan for hosts it sends M-SEARCH * messages every other second, which can result in lots of replies, which in turn causes ssdp-scan to retrieve XML files from each replying host. so like… be careful. genuinely. 💀

unless started with the -t SEC option, ssdp-scan does not terminate on its own. instead, it scans continuously until the user stops it by pressing Ctrl+C. she will simply keep going forever, no cap 😭

ssdp-scan does not rely on a local SSDP responder. she has no dependencies besides a standard UNIX libc. low maintenance queen 👑
