IPSEC-CHECKNSS(8)

✨ IPSEC-CHECKNSS ✨ (that's section 8 bestie, executable programs energy)

okay so you know how I'm always saying the NSS database is the whole entire vibe?? This page is ipsec-checknss, and honestly? It's giving lowkey essential. It's a LibreSwan 5.4.1 situation. Come sit, I'll explain. 🫶

💖 NAME 💖

ipsec-checknss — checks or initializes the IPsec NSS database. That's it. That's the whole job. And she does it beautifully. ✨

---

🎀 SYNOPSIS 🎀

ipsec checknss [--nssdir /var/lib/ipsec/nss] [--settrusts]

ngl the page just hands you these two flags with zero OPTIONS section to explain them, and we respect the mysterious main character energy. 🙈 Everything the page actually does tell you is right here, so I'm not gonna make stuff up. Periodt.

🌸 DESCRIPTION 🌸

So. checknss checks the NSS database, or initialises it — that's the place where all the private keys for RSA and certificate keypairs live. Like, your entire key situation. The vibes. The whole archive. 🔐

Now here's the part you need to actually remember, bestie: if you wanna remove an existing IPsec NSS database, you don't run some cute delete command — you go into the NSS data directory (default: /var/lib/ipsec/nss) and remove all the *.db files and pkcs11.txt. Those specific files. That's the move.

🚨 Like, actually remove the files. Please don't just start deleting random stuff in there without knowing what you're doing, okay?? Keys are not a casual thing to yeet. 💀

And the happy path? If the database exists, it returns successfully. Clean. No drama. Slay. 💅

and that's the whole page, bestie!! 🌈✨ Go forth, check those databases, initialise them if they need it, and if you're removing one, remember: *.db files plus pkcs11.txt, from the NSS data directory (default /var/lib/ipsec/nss). You've got this. 💖
