cnetz_magnetic(1)

✨ NAME ✨

cnetz_magnetic — bestie, it's the C-Netz magnetic card simulator 💳✨, and its whole documentation home lives at http://osmocom-analog.eversberg.eu/docs/ 🫶

This is a section 1 page from the General Commands Manual — you know, the big book of "just type it and it runs" commands. 💅

🎀 SYNOPSIS 🎀

cnetz_magnetic [options] -a hw:0,0 <number> | service

So like… you hand it some options, you tell it where your audio is coming in with -a hw:0,0, and then you either give it a number or the word service. That's the whole vibe. 🌸

🌈 General options

🌈 General options

• -h --help — the classic. Prints this help. That's it, that's the option. 🫶
• --config [~/]<path to config file> — point it at a config file to use. If the path starts with ~/, the file lives in your home dir 🏠. Every single line in that config file is one option, and ngl — you must not write - or -- in there. Just the option, bare. Periodt.
• -v --verbose <level> | <level>,<category>[,<category>[,...]] | list — the chatter dial 🗣️. Throw list at it and it'll give you every level and category that exists. With just a level: it's a digit for the debug level, and the default is 3. With level plus categories: you give the level digit first, then one or more categories after it → and if you don't name any category, all the categories get selected. Slay, everything at once. 💅
• -v --verbose date — this flavor makes the debug output show the date too 📅✨
• -a --audio-device hw:<card>,<device> — pulls the input audio from your sound card's device number 🎧
• -s --samplerate <sample rate> — the audio device sample rate in Hz. Default is 48000. 🎵
• -w --write-wave <filename> — dumps the sound out as a wave file 💾🦋

💳 Magnetic card simulator options

• -B --baud-rate <baud> — the playback baud rate. Default is 2666. 🔥
• -S --sicherung <security code> — the card's security code for simple authentication 🔐. Default is '12345' (yes, really, iconic). 👑

🧚 What you actually pass at the end

• <number> — give any valid 7 digit subscriber number (optionally 8 digit, we're flexible ✨). It may be prefixed with 0160.
• 'service' — the BSA44 service card 🛠️, which exists to unlock your phone after a battery replacement. The way that battery-swap amnesia is so real 😭🔋

Heads up bestie: in the config file, remember — one option per line, and no - or -- prefixes. Just don't do it. 🙈

Anyway, that's the whole page 🫶 — straight from page 1 of the General Commands Manual, filed under the name cnetz_magnetic(1), brought to you by the fine folks over at http://osmocom-analog.eversberg.eu/docs/. Go forth and simulate some cards, mwah 💋💖
