BPUTA(1)

📦 version 3.2.1, in ubuntu jammy

💖 BPUTA(1) — like, the whole vibe 💖

okay bestie, so this is the tea on bputa, one of the CFDP executables — yes, it's giving "manual page" but make it cute. it's bputa from the CFDP crew, and i'm about to tell you everything about it. no gatekeeping here. 🫶

✨ NAME ✨

bputa — the BP-based CFDP UT-layer adapter. that's it, that's the name, and honestly? iconic. 👑

🌸 SYNOPSIS 🌸

bputa

yeah. that's the whole thing. no flags, no arguments, no drama. she just runs. 💅

🦋 DESCRIPTION 🦋

so bputa is a background "daemon" task — like, the quiet bestie in the group chat who's actually getting everything done — and what she does is send and receive CFDP PDUs encapsulated in DTN bundles. that's the whole job. main character energy but make it infrastructure. ✨

here's the part you gotta know: nobody spawns her by hand. she gets spawned automatically by cfdpadmin in response to the 's' command — the one that starts operation of the CFDP protocol. and lowkey important: the text of the command that is used to spawn the task must be provided as a parameter to the 's' command. so cfdpadmin needs the receipt, basically. 🧾

and when it's time to go? the link service input task is terminated by cfdpadmin in response to an 'x' (STOP) command. she does not leave on her own terms. periodt. 💀

🎀 EXIT STATUS 🎀

  • "0" — bputa terminated normally, for reasons noted in the ion.log file. okay so if this wasn't, like, commanded, you gotta investigate and solve the problem identified in the log file, then use cfdpadmin to restart bputa. not me telling you to read the logs. bestie. READ THE LOGS. 😭
  • "1" — bputa terminated abnormally, for reasons noted in the ion.log file. investigate and solve the problem identified in the log file, then use cfdpadmin to restart bputa. she didn't choose this life, but here we are. 🚨

🍓 FILES 🍓

no configuration files are needed. zero. none. she's low maintenance, we love that for her. 💖

🌈 ENVIRONMENT 🌈

no environment variables apply. nothing to export, nothing to source. clean girl aesthetic. ✨

👑 DIAGNOSTICS 👑

okay so these are the messages that may get issued to the ion.log log file. they're basically bputa texting the group chat that something's up. let's go through them one by one, no skipping, i said what i said. 💅

  • CFDP can't attach to BP. — bpadmin has not yet initialized BP protocol operations. like, the BP protocol isn't even up yet. chill. 🙈
  • CFDP can't open own endpoint. — most likely another bputa task is already running. so use cfdpadmin to stop CFDP and restart. two of her? in this economy? no. 💀
  • CFDP can't get Bundle Protocol SAP. — most likely a BP configuration problem. use bpadmin to stop BP and restart. something's off in the BP setup, bestie. 🔧
  • bputa can't attach to CFDP. — cfdpadmin has not yet initialized CFDP protocol operations. she's knocking but nobody's home. 😭
  • bputa can't dequeue outbound CFDP PDU; terminating. — possible system error. check ion.log for additional diagnostic messages. she's out, fr fr. 🚪
  • bputa can't send PDU in bundle; terminating. — possible system error. check ion.log for additional diagnostic messages. the bundle just didn't bundle. 💔
  • bputa can't track PDU; terminating. — possible system error. check ion.log for additional diagnostic messages. can't track it, can't keep it. ✌️
  • bputa bundle reception failed. — possible system error; reception thread terminates. check ion.log for additional diagnostic messages. the reception thread said "i'm done" and honestly, valid. 🫠
  • bputa can't receive bundle ADU. — possible system error; reception thread terminates. check ion.log for additional diagnostic messages. 🚫
  • bputa can't handle bundle delivery. — possible system error; reception thread terminates. check ion.log for additional diagnostic messages. she cannot handle it. literally cannot. 😭
  • bputa can't handle inbound PDU. — possible system error; reception thread terminates. check ion.log for additional diagnostic messages. the inbound PDU said hi and she said no. 🙅
pro tip from your girl: any time it says "check ion.log for additional diagnostic messages," that's your cue to actually go check ion.log. i'm not saying it's the answer. i'm saying it's an answer. 👀

and that's the whole page, bestie!! 🎀 one last lil thing: this manual page is perl v5.24.1, dated 2016-07-07, and it's part of the CFDP executables. she's been here since 2016 and she's still serving. periodt. 💖🦋🌸🫶👑
