💅 firehol-tosfix(5) — the tosfix glow-up guide ✨

okay bestie, welcome to firehol-tosfix from the FireHOL fam (that's the manual page firehol-tosfix(5), in case you were wondering which one you opened) 🫶 this one is short and sweet and honestly kinda iconic.

🌸 NAME 🌸

firehol-tosfix — slaps suggested TOS values onto packets 💖

---

🎀 SYNOPSIS 🎀

tosfix

that's it. one word. no args. no notes. periodt. 💅

---

✨ DESCRIPTION ✨

so the tosfix helper command sets the Type of Service (TOS) field in packet headers, and it does it based on the suggestions that Erik Hensema dropped in iptables and tc shaping tricks. king behavior, honestly 👑

here are the TOS values it sets, no cap:

• All TCP ACK packets with length less than 128 bytes get assigned Minimize-Delay, while the bigger ones get assigned Maximize-Throughput 🌈
• All packets that have TOS Minimize-Delay and are bigger than 512 bytes get bumped up to Maximize-Throughput — except for short bursts of 2 packets per second (those lil bursts get to keep their vibe, we love that for them 🦋)

🚨 real talk bestie: the tosfix command must be used before the first router or interface. like, before. not after. timing is everything, iykyk 💀

🌟 EXAMPLE 🌟

tosfix

yes, the example is literally just the command again. it's giving minimalism. it's giving main character energy. ✨
