Firewall(3pm)

💖 Firewall(3pm) — Lire::Firewall 🎀

okay bestie, so this is a page from LogReport's Lire Documentation and it's literally called Firewall(3pm), and the whole module is Lire::Firewall. Buckle up, it's a short one but it slaps 💅

---

✨ NAME ✨

Lire::Firewall — no cap, this module hands you a subroutine that does TCP and UDP portnumber-to-name mapping. that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

like, literally just do this:

use Lire::Firewall qw/:firewall_number2names /;

yes, that trailing space before the closing slash is canon, don't @ me 🙈

---

🦋 DESCRIPTION 🦋

okay so Lire::Firewall::firewall_number2names takes numbers for network services — the exact kind you keep seeing in firewall log files — and converts them into their descriptive names. it's giving "translator bestie" energy ✨

then there's firewall_revolve which is FIXME TODO 😭 like it's literally marked as unfinished, we respect the vulnerability

it takes a firewall Lire dlf object as its argument, and it operates on that object's to_port, from_port and protocol properties. those three, periodt 👑

what's supported? TCP services, UDP services and ICMP types — all three ate, all three are iconic 🌈

---

🔥 SEE ALSO 🔥

• RPC 792 for ICMP types. that's the reference, go read it iykyk 📚

---

⭐ VERSION ⭐

$Id: Firewall.pm,v 1.5 2006/07/23 13:16:27 vanbaal Exp $

the version string, preserved in all its glory, exactly as it was, we love a time capsule 🎀
