NRATTACH(8)

💖 NRATTACH 💖

okay bestie, welcome to the NRATTACH(8) page — that's section 8 of the Linux System Managers Manual, aka the place where all the system-manager-y commands live. no cap, this one's a lil niche but it's so useful if you're doing NET/ROM things. let's get into it 🎀

✨ NAME ✨

nrattach — start a NET/ROM interface 🦋

🌸 SYNOPSIS 🌸

nrattach [-i inetaddr] [-m mtu] [-v] port

🫶 DESCRIPTION 🫶

okay so here's the tea. nrattach takes a bunch of the parameters for the port from the nrports(5) file — like, it's not out here making stuff up, it's reading the file, periodt.

the paclen parameter is what gets used for the device mtu, unless you override it with a value on the command line. you're in charge, queen 👑

the port argument is the name of a port, exactly as it's given in the nrports(5) file. that's it, that's the arg.

then — and this is the main character moment — nrattach goes looking for the first free NET/ROM device in the system. it checks them in this order, one by one:

1. nr0
2. nr1
3. nr2
4. nr3

if there's no free NET/ROM device available, it throws an error and the program just... terminates. 💀 no device, no vibes, we go home.

💅 OPTIONS 💅

• -i inetaddr — set the internet address of the interface. this address can be either a dotted decimal address or a host name, whichever you vibe with ✨
• -m mtu — sets the mtu of the interface. if you don't give this value, it gets taken from the paclen parameter in nrports. so like, it's covered either way 🫶
• -v — display the version. simple. iconic. 💖

🌈 SEE ALSO 🌈

• netrom(4)
• nrparms(4)
• nrports(5)
• ifconfig(8)

go read those too, iykyk 📚

😭 BUGS 😭

okay so this is the part where we hold hands and be honest. the program can be run many times with the same arguments, which creates many instances of the same attributes on different devices.

that's it. that's the bug. not a good idea. bestie please don't. 🙈
