KDUMPD(8)

💖 KDUMPD(8) — System Manager's Manual energy 💖

okay so bestie, this is kdumpd from the System Manager's Manual (section 8, iykyk) — your Mac OS X remote kernel core dump server. She's not like other girls; she catches kernel states. 🦋

🌸 NAME 🌸

kdumpd — Mac OS X remote kernel core dump server. That's it, that's the name, and honestly? Iconic. 💅

✨ SYNOPSIS ✨

/usr/libexec/kdumpd [directory]

💅 DESCRIPTION 💅

Kdumpd is a server that receives kernel states in the form of a core dump from a remote Mac OS X machine. Think of her as the friend who catches the panic dump so you don't have to. 🫶

She operates on UDP port 1069, although this may be configurable in the future — future, bestie, not now. 👀

The server should be started by launchctl(1). That's the launch move. ✨

Run her with the user ID with the lowest possible privilege — usually the user "nobody". Lowkey the safest vibe. 🎀

By default, she stores kernel cores in the directory /var/tmp/PanicDumps. The directory needs to already exist for kdumpd to save core dumps — so make it first, okay? 😭

If she receives a request for an existing file, she returns an EEXIST error to the remote kernel. Translation: only new files can be created. No overwrites, no drama, no cap. 💀

She also disallows path specifications in the incoming file name. So don't try to slip a path in there, bestie — she's not falling for it. 🚫

🦋 HISTORY 🦋

The kdumpd command is based on Berkeley tftpd(8), by way of FreeBSD, with several modifications. Ancestry? Gorgeous. Lore? Immaculate. 👑
