IPSEC-_UPDOWN(8)

💖 NAME 💖

ipsec-_updown.xfrm — the routing manipulation script, bestie ✨

It's a whole little script whose entire job is moving routes around. Yeah. That's the gig. And it does it flawlessly.

🌸 SYNOPSIS 🌸

_updown

Okay so here's the tea ☕ — _updown is invoked by pluto when pluto has brought up a new connection. Like, pluto finishes the handshake, looks around, and goes "okay _updown, you're up" 🫶

And this script's main character moment? It inserts the appropriate routing entries for IPsec operation. That's it. That's the whole vibe. Routes go in, IPsec works, everyone eats 💅

And if you're sitting there like "but how do I even talk to this script, what's the interface" — bestie, the interface to the script is documented in the pluto man page. Not here. Go read ipsec-pluto(8). I'm not gatekeeping, I'm just telling you where the lore lives 📖✨

Heads up: this page is short on purpose. The real deets live in pluto's man page, fr fr. Don't come for me, come for ipsec-pluto(8). 🙈
