💅 RXECHO(8) — the Linux System Managers Manual page, but make it make sense 🎀

okay bestie, grab a snack 🍓 because we're talking about rxecho — it lives in section 8 of the Linux System Managers Manual and it's genuinely one of those quiet little utilities that just does the thing with zero drama. no cap.

✨ NAME ✨

rxecho — Route AX.25 packets between ports transparently. 🦋

like, transparently transparently. nobody downstream even notices.

🌸 SYNOPSIS 🌸

rxecho [-l] [-v]

that's it. two flags. main character energy, minimal effort. 👑

💖 DESCRIPTION 💖

so here's the vibe: rxecho copies AX.25 frames between interfaces without altering their contents. it doesn't rewrite them, it doesn't sprinkle anything on top, it just picks them up and puts them somewhere else. iconic behaviour honestly. ✨

and why would you want that? okay so the whole point of this utility is to let other AX.25-aware programs and computers share the same AX.25 ports that the Linux kernel AX.25 code is using. it's giving "everybody gets a turn at the radio port." 🤝

some real scenarios, since you asked:

  • you could route packets out onto another serial port so a whole other machine running DOS-based programs gets to share the same radio ports as the Linux machine 🖥️
  • or you could route them out onto a pseudo-tty to another application sittin' on the same machine 🧚
  • the copying could even go out to another radio port 📻

no thoughts, just forwarding.

and the copying itself? it's controlled by a configuration file, rxecho.conf(5), which you set up to selectively copy packets. so you pick who gets copied where. you're in charge. 💅

🔥 OPTIONS 🔥

  • -l — Enables logging of errors to the system log. the default is off, so if you want the receipts you gotta ask for them, bestie. 📝
  • -v — Display the version. tiny flag, big "who am i" energy. ⭐

💀 lowkey reminder: rxecho copies frames unmodified between interfaces. the config file is what decides which packets get copied — so if the routing looks weird, go check rxecho.conf(5) before you spiral. 🙈

mwah 💋 that's the whole page, bestie. this one came out of the Linux world, dated 27 April 2008, and it's officially a wrap. go configure your ports. slay. 🎀✨
