DCCPLSO(1)

💫 DCCPLSO(1) 💫

okay bestie, pull up a chair, we're reading the dccplso(1) page from the LTP executables manual and honestly? it's giving main character energy for the whole DCCP link service situation 🦋

---

✨ NAME ✨

dccplso — the DCCP-based LTP link service output task. that's it, that's the girl 💅

---

🌸 SYNOPSIS 🌸

dccplso {remote_engine_hostname | @}[:remote_port_nbr] remote_engine_nbr

---

💖 DESCRIPTION 💖

so dccplso is a background "daemon" task — yes the quotes are in the original, we love a humble queen — and what she does is: she reaches into the queue of LTP segments that are headed for the remote LTP engine you pointed at, yoinks them out, wraps them up all cozy in DCCP datagrams, and ships those datagrams off to the DCCP port you named on the host you named. no cap. 📦✨

if you don't specify the port number, it lowkey just defaults to 1113. iconic of her.

every single "span" of LTP data interchange between your local LTP engine and a neighboring LTP engine needs its own link service output task, like dccplso. so yeah, one per span, she's not sharing 🫶

and here's the thing — you don't even spawn these yourself. all link service output tasks get spawned automatically by ltpadmin when you hit it with the 's' command that starts up LTP protocol operations. and when you want them gone, ltpadmin terminates every single one of them in response to an 'x' (STOP) command. group chat mod behavior, honestly.

---

💀 EXIT STATUS 💀

• "0" — dccplso terminated normally, for reasons noted in the ion.log file. if this termination was not commanded by you, bestie go investigate, solve the problem the log file is pointing at, and use ltpadmin to restart dccplso. 🔍
• "1" — dccplso terminated abnormally, for reasons noted in the ion.log file. investigate, solve the problem identified in the log file, then use ltpadmin to restart dccplso. same energy, worse vibe 😭

---

🎀 FILES 🎀

No configuration files are needed. literally zero. she's low maintenance, we stan 💜

---

🌈 ENVIRONMENT 🌈

No environment variables apply. none. nada. the environment is not her business ✨

---

🔥 DIAGNOSTICS 🔥

these are the diagnostics that may get dropped into the ion.log log file, so pay attention:

• dccplso can't initialize LTP. ltpadmin has not yet initialized LTP protocol operations. girl is not ready yet, wait for her 💅
• No such engine in database. remote_engine_nbr is invalid, or the applicable span hasn't been added to the LTP database by ltpadmin yet. check your number, check your span 🙈
• LSO task is already started for this engine. redundant initiation of dccplso. she's already here, bestie, she's already on the clock 😭
• LSO can't create idle thread. operating system error. check errtext, correct the problem, and restart dccplso.
• LSO can't open DCCP socket. This probably means DCCP is not supported on your system. operating system error. this probably means you are not using an operating system that supports DCCP. make sure you're running a current Linux kernel and that the DCCP modules are being compiled. check errtext, correct the problem, and restart dccplso. 🧚
• LSO can't connect DCCP socket. the remote host's dccplsi isn't listening or has terminated. restart dccplsi on the remote host and then restart dccplso. like, both of them. in that order. 👑
• Segment is too big for DCCP LSO. configuration error: segments that are too large for DCCP transmission (i.e., larger than 65535 bytes) are being enqueued for dccplso. use ltpadmin to change the maximum segment size for this span. that's a whole lotta bytes and DCCP said no 💀
