MACTELNETD(8)

💖 MACTELNETD 💖

okay bestie, gather round, because we're talking about mactelnetd from section 8 of the System Manager's Manual, and she is iconic. This is the Telnet daemon for MAC-address connections, and yes, she's serving main character energy on your local network. 🎀

✨ NAME ✨

mactelnetd — Telnet daemon for MAC-address connections

---

🌸 SYNOPSIS 🌸

mactelnetd [options]

---

🦋 DESCRIPTION 🦋

So here's the vibe: this daemon just sits there, minding her own business, listening for telnet connections. From who? From Mikrotik RouterOS devices or mactelnet clients that are on the same physical network as her. That's the whole friend group, right there. 🫶

And that's not even all — she's also out here announcing her hostname via the MNDP protocol every minute. Every. Single. Minute. Consistent queen. ⏰✨

💅 OPTIONS 💅

These programs follow the usual GNU command line syntax, bestie — nothing weird, nothing custom, just classic GNU behaviour. A summary of the options is included below, and I'm giving you all of them, no skips. 💖

• -n — Do not use broadcast packets. Lowkey a tad less insecure. What this means: the ethernet packets will have the mac-address of the client as the packet destination, instead of using the ethernet broadcast address. Fancy, targeted, direct. 💌
• -o — Use the older MD5 based authentication. Heads up, this one is less secure, and it also requires your userfile to have the passwords in plaintext format. And here's the tea: if you're running the server with this parameter, you cannot add users using the -a option. Periodt. 🚫
• -a — Add a new user. The user should be an existing user in your system. Cute part? You can do this without restarting your mactelnetd server, because she re-reads the user file for each authentication attempt. She's nothing if not thorough. You'll be prompted for the username and password, OR you can use one of the following options to specify them on the command line:
  • -u username — You can specify the new username to add on the command line using this option. If this is not used, you will be prompted for the username. 💬
  • -p password — You can specify the new password for the new user to add on the command line using this option. If this is not used, you will be prompted for the password. 🔐
• -d username — Delete the specified user. Bye bestie, it's not you it's the config file. 👋
• -l — List the available users in the /usr/local/etc/mactelnetd.users file. Window shopping, but make it auth. 🛍️
• -h — Show summary of options. Help me help you. 🆘
• -v — Show version of program. Know your era. ⭐

🍓 FILES 🍓

• /usr/local/etc/mactelnetd.users — This file contains a line separated list of users that will have access to your machine. Usernames and passwords are separated by colon. And the way that she re-reads this file each time a user connects?? Obsessed. Literally re-reading it every single time. No caching, no stale data, just fresh vibes. 🌈
