💅 lltdscan — the manual page, but make it cute

okay so bestie, welcome to lltdscan(8) — yes, section 8, the sysadmin section, we love a system administration moment 🎀

✨ NAME ✨

lltdscan — scan for LLTD-enabled hosts on a network interface. that's it, that's the girl. she finds the LLTD girlies for you 🦋

🌸 SYNOPSIS 🌸

lltdscan [-i iface] [-t timeout] [-u] [-v] [-v] [aa:bb:cc:dd:ee:ff]

💖 DESCRIPTION 💖

so here's the vibe. the lltdscan utility sends a broadcast LLTD request on the interface you specify (or the default one if you're feeling lowkey and didn't specify anything). and then? she listens. for timeout milliseconds, waiting for responses to come home like a girl waiting for a text back. 💌

want her to be more chatty? add one or two -v options to increase verbosity. two is highkey the maximum useful dose — go off, verbose queen 👑

add the -u option and she'll show you the machine names in UTF-8. unicode girlies rise 🙈

and here's the spicy part: you can specify exactly one MAC address as the last argument — and lltdscan will exit as soon as it receives the first reply from that specified host. no waiting around, no filler episodes, main character energy only. as soon as that host answers, she's out. periodt. 💅

🌈 LLTD PROTOCOL 🌈

okay so what even is LLTD? it stands for "Link Layer Topology Discovery." iconic acronym, no notes. ✨

the protocol specs are available from Microsoft at: http://www.microsoft.com/whdc/connect/Rally/LLTD-spec.mspx

(go read them if you're that kind of girl — and honestly, you might be 🧚)
