RST(8)

💅 RST(8) — like, the manual page bestie

okay so you found the page for rst, the little chaos goblin that lives in section 8 of your System Manager's Manual. Pull up a chair, grab a boba, we're doing this. 🧋✨

🌸 NAME 🌸

rst — terminate an established TCP connection 💀✂️

✨ SYNOPSIS ✨

rst [ -R ] [ -I text-to-inject ]
    [ -i interface ]
    [ -d delay-msec ]
    [ -n num ]
    [ -r redundancy ]
    [ -s stride ]
    from_addr from_port from_seq to_addr to_port to_seq

🦋 DESCRIPTION 🦋

So here's the vibe: rst is a utility that a Bro script can invoke, and what it does is terminate an established TCP connection by forging RST tear-down packets. Yeah. It just. Makes the connection not exist anymore. No handshake, no goodbye text, no "we should hang out soon" — just a forged reset straight to the face and the convo is over. 💅

No cap, that's the whole plot. 👑

🎀 OPTIONS 🎀

Lowkey the page is not giving us a whole essay on each flag, so here's exactly what it hands you — names and placeholders, kept character for character because we do not edit the source material in this house:

• -R — it's a flag, no argument, that's all the page says. 🙈
• -I text-to-inject — takes a text-to-inject value. 📩
• -i interface — takes an interface. 🌐
• -d delay-msec — takes a delay-msec value, in milliseconds, bestie. ⏱️
• -n num — takes a num. 🔢
• -r redundancy — takes a redundancy value. ♻️
• -s stride — takes a stride value. 👟

And then the positional arguments, in this exact order, no skipping, no swapping, the order matters fr fr:

• from_addr
• from_port
• from_seq
• to_addr
• to_port
• to_seq

⚠️ Also just so we're clear: this is a forging packets situation, so please only point it at connections you're actually allowed to kill. Don't be weird about it. 🫶
