LTPCLI(1)

📦 version 3.2.1, in ubuntu jammy

💖 LTPCLI — the LTP-based BP convergence layer input task 💖

okay bestie, gather round, because ltpcli is genuinely one of those little background tasks that just works and nobody ever thanks her. she's part of the BP executables crew, and she's about to become your new fave. no cap. 🫶

✨ NAME ✨

ltpcli — the LTP-based BP convergence layer input task. that's the whole vibe. she receives, she extracts, she delivers. main character energy fr fr. 👑

🌸 SYNOPSIS 🌸

ltpcli local_node_nbr

that's it. one arg. we love a low-maintenance queen. 💅

🦋 DESCRIPTION 🦋

so here's the tea: ltpcli is a background "daemon" task that:

  1. receives LTP data transmission blocks,
  2. extracts bundles out of the received blocks,
  3. passes them along to the bundle protocol agent on the local ION node.

three-step routine, iconic, no notes. ✨

now, who starts her? bpadmin does, automatically, in response to the 's' (START) command that starts operation of the Bundle Protocol. and listen — the text of the command used to spawn the task must be provided at the time the "ltp" convergence layer protocol is added to the BP database. like, that's not optional, bestie. 🙈

and when it's time to go? the convergence layer input task is terminated by bpadmin in response to an 'x' (STOP) command.

bonus round: ltpcli can also be spawned and terminated in response to START and STOP commands that pertain specifically to the LTP convergence layer protocol. versatile queen. 💜

⭐ EXIT STATUS ⭐

  • "0" — ltpcli terminated normally, for reasons noted in the ion.log file. if this termination was not commanded, investigate and solve the problem identified in the log file, and use bpadmin to restart ltpcli. 👀
  • "1" — ltpcli terminated abnormally, for reasons noted in the ion.log file. investigate and solve the problem identified in the log file, then use bpadmin to restart ltpcli. 😭

🎀 FILES 🎀

No configuration files are needed. she's self-sufficient. zero baggage. periodt. 💅

🌈 ENVIRONMENT 🌈

No environment variables apply. nothing to export, nothing to unset. breathe. 🧘‍♀️

🔥 DIAGNOSTICS 🔥

these are the messages that might get sent to the ion.log log file. read them, they're literally telling you what's wrong:

  • ltpcli can't attach to BP. — bpadmin has not yet initialized Bundle Protocol operations. 😭
  • No such ltp duct. — no LTP induct matching local_node_nbr has been added to the BP database. use bpadmin to stop the LTP convergence-layer protocol, add the induct, and then restart the LTP protocol. 🫠
  • CLI task is already started for this duct. — redundant initiation of ltpcli. she's already here bestie, chill. 🙈
  • ltpcli can't initialize LTP. — ltpadmin has not yet initialized LTP operations. 💀
  • ltpcli can't open client access. — another task has already opened the client service for BP over LTP. 💀
  • ltpcli can't create receiver thread — operating system error. check errtext, correct problem, and restart LTP. 🔧
