LSSTP(8)

💅 LSSTP — the STP tea-spiller 💅

okay so real quick, this page lives in the Linux Administrator's Manual (section 8, sysadmin stuff, you know the vibe), and it's literally just lsstp — that's it, that's the whole command. Let me tell you everything it spills. 🫶

---

✨ NAME ✨

lsstp — shows you the STP configuration info. like, the current Server Time Protocol setup. clock gossip, basically. ⏰

---

🎀 SYNOPSIS 🎀

lsstp

no flags, no args, no drama. she just runs. 💅

---

🌸 DESCRIPTION 🌸

lsstp displays information about the current Server Time Protocol (STP) configuration — like the coordinated time network (CTN) ID, the timing state, and leap seconds. it's giving "let me check my clock's whole personality" energy. ✨

---

🦋 OUTPUT 🦋

here's every single thing she can print at you, and what it means. no cap, all of it: 💖

• STP online — indication of the online state. is STP up or not, that's the vibe check.
• CTN ID — the ID of the coordinated time network. if it can be decoded as EBCDIC it's shown as an EBCDIC string, otherwise you get a hexadecimal representation. either way she's showing you something. 🔥
• CTN Type — the type of timing network:
  • No CTN — STP is not configured for attachment to a CTN.
  • STP-only — STP is configured and attached to a CTN with only STP nodes.
  • Mixed — STP is configured and attached to a CTN with both STP and external time reference (ETR) nodes.
• Stratum — the number of servers in the timing path between the local STP clock and the selected primary time server. think of it as how many hops away your time source is living. 🌈
• Timing mode — how the TOD clock is doing:
  • Local — the Time-of-day (TOD) clock is stepped by the local hardware oscillator and is not steered by the STP facility. she's on her own, main character energy.
  • ETR — the TOD clock is synchronized with an attached 9037 Sysplex Timer.
  • STP — the TOD clock is steered by the STP facility to maintain synchronization with a Coordinated Server Time (CST).
  • Uninitialized — the TOD clock is not initialized. the STP facility is allowed to perform a step adjustment to the TOD clock for synchronization. 😭
• Timing state — the synchronization state of the STP facility. can be unsynchronized, synchronized or stopped.
• DST offset — the daylight savings time offset relative to UTC, in minutes. 🍓
• Timezone offset — the offset of the local time relative to UTC, in minutes.
• Time offset — the total time offset at the server. ⚠️ this field is only valid in mixed CTN configurations, so don't come for her if it's not giving anything in other setups.
• Active leap seconds — the number of leap seconds that are currently in effect at the STP facility. yes, plural, she can stack.
• Leap second \<insertion|deletion\> at — if a leap second insertion or deletion is scheduled in the STP facility, this field shows the day and time of the scheduled change. mark your calendar bestie. 📅

✨ and that's the whole page, bestie ✨ — this little beauty comes from the s390-tools and the date on it is Jul 2020, so go forth and check your STP configuration with confidence. mwah. 💋🎀
