PPPX(4)

💅 PPPX(4) — like, the PPP multiplexer device bestie ✨

okay so this is a page from the Kernel Interfaces Manual, and it's about pppx and pppac, the PPP multiplexer device(s). two icons, one manpage. let's get into it 🫶

---

✨ NAME ✨

pppx, pppac — the PPP multiplexer device. that's the whole vibe. 💖

---

🎀 SYNOPSIS 🎀

pseudo-device pppx

and you're gonna need these headers, no cap:

#include <sys/socket.h>
#include <sys/ioctl.h>
#include <net/pipex.h>

---

🌸 DESCRIPTION 🌸

so. the pppx and pppac drivers team up with the npppd(8) daemon to hand out network interfaces for Point-to-Point Protocol (PPP) sessions — and they do it by request from the daemon, like a little assistant that only acts when asked. 💅

here's the difference between the two, bestie, write it down:

• pppx operates by allocating a network interface for each PPP session. one session, one interface. main character energy for every single session. 👑
• pppac concentrates multiple PPP sessions on a single network interface. it's giving group-chat, everyone in one place. 🫶

both interfaces also work with pipex(4) to accelerate the performance of data packet forwarding — speed ✨ — and they support the ioctls which are added by pipex(4).

okay now the setup part, don't skip this 🙈 to use pppx or pppac from npppd(8), the administrator needs to configure the interface configuration in npppd.conf(5). and the administrator also needs to enable pipex(4) by setting net.pipex.enable to '1' using sysctl(8). both steps. yes, both. i don't make the rules, i just think they're iconic.
