🌸 _UPDOWN(8) 🌸

okay so real quick before anything else: this page lives in the Executable programs manual, section 8 (that's the big-girl system-admin section, iykyk 💅). the page itself is called _UPDOWN, and honestly? she's a little legend.

✨ NAME ✨

ipsec__updown.xfrm — the klips manipulation script 🎀

like, that's her whole job description. klips. manipulation. script. iconic behavior ngl.

🦋 SYNOPSIS 🦋

so _updown gets invoked by pluto when it has brought up a new connection — pluto's basically the one calling the shots, and _updown is the bestie who shows up to do the actual legwork 💪

this script is used to insert the appropriate routing entries for IPsec operation.

and where do you learn how to talk to this script, you ask? the interface to the script is documented in the pluto man page. periodt. go read that one for the deets 👑

🍓 AUTHOR 🍓

Paul Wouters placeholder to suppress warning

(that's right bestie, the entire author description is "placeholder to suppress warning" — she's a placeholder and she's doing her job beautifully, no notes 😭💀)
