BPECHO(1)

✨ BPECHO(1) ✨

ok so like, welcome to the BPECHO manual page bestie 💖 this one lives in the BP executables section of the manual (that's the 1 in BPECHO(1), iykyk), and it's literally the cutest tiny little test program you've ever seen. grab a snack, we're going in 🍓

🎀 NAME 🎀

bpecho — the Bundle Protocol reception test program. that's it, that's the whole vibe, she receives and she echoes back, no cap 💅

🦋 SYNOPSIS 🦋

bpecho ownEndpointId

🌸 DESCRIPTION 🌸

okay so here's the tea ☕ bpecho uses Bundle Protocol to receive application data units from a remote bpdriver application task. that's the whole job. she's a receiver, she's a listener, she's the main character of this little conversation 🫶

and the way that she responds to each received application data unit?? she sends back an "echo" application data unit of length 2 — which is literally just the NULL-terminated string "x". iconic behavior honestly. she said "x" and meant it 💜

bpecho terminates upon receiving the SIGQUIT signal, i.e., ^C from the keyboard. so when you're done hanging out with her, that's the goodbye signal 👋

💅 EXIT STATUS 💅

  • "0" — bpecho has terminated normally. any problems encountered during operation will be noted in the ion.log log file. so like, she left cleanly, but bestie... check the log anyway, fr fr 👀
  • "1" — bpecho has terminated due to a BP reception failure. details should be noted in the ion.log log file. 😭 she didn't make it, the log knows why

🧚 FILES 🧚

no configuration files are needed. zero. none. nada. she's low maintenance, she's unbothered, she simply runs ✨

🌈 ENVIRONMENT 🌈

no environment variables apply. none of them. not a single one showed up to the party 🙈

👑 DIAGNOSTICS 👑

diagnostic messages produced by bpecho are written to the ION log file ion.log. so that's where you go snooping when things get weird 🔍

  • Can't attach to BP. bpadmin has not yet initialized Bundle Protocol operations. like... nobody set up the party yet, bestie. run bpadmin first 🎈
  • Can't open own endpoint. another application has already opened ownEndpointId. terminate that application and rerun. she's taken, the endpoint is occupied, you gotta evict the squatter 💀
  • bpecho bundle reception failed. BP system error. check for earlier diagnostic messages describing the cause of the error; correct problem and rerun. classic "read the earlier messages" situation, don't skip them 🙏
  • No space for ZCO extent. ION system error. check for earlier diagnostic messages describing the cause of the error; correct problem and rerun. same energy, same fix 🫡
  • Can't create ZCO. ION system error. check for earlier diagnostic messages describing the cause of the error; correct problem and rerun. yes bestie, again 🔁
  • bpecho can't send echo bundle. BP system error. check for earlier diagnostic messages describing the cause of the error; correct problem and rerun. her echo got stage fright 😔
pro tip from me to you: every single one of these says "check for earlier diagnostic messages" because the earlier messages are literally where the actual explanation lives. the last error is never the whole story. go read the log, bestie 📜
