S6-IDENT-CLIENT(8)

📦 version 2.8.0.1, in nixpkgs unstable

💅 s6-ident-cliENT — like, the NAME bit

okay so bestie, meet s6-ident-client — a command-line client application that performs IDENT (RFC 1413) queries. that's it, that's the whole vibe. it asks the internet "hey who's that?" and the internet (hopefully) answers 🎀

(this whole page lives in section 8 of the System Manager's Manual, iykyk ✨)

✨ SYNOPSIS ✨

s6-ident-client [-t millisecs] remoteaddr remoteport localaddr localport

four arguments. no cap, you need all of them 👑

🌸 DESCRIPTION 🌸

So here's the tea ☕ — s6-ident-client contacts the IDENT server on address remoteaddr port 113, and asks it about the connection from address remoteaddr port remoteport to address localaddr port localport.

It prints the answer to stdout. literally just prints it. iconic behaviour 💅

Then the exit status does the talking:

  • exits 0 if the answer is positive 🟢
  • exits 1 if the answer is negative 🔴 — and in that case it also prints an informative message to stderr, so you're not just standing there confused 🫶

remoteaddr and localaddr can be either IPv4 or IPv6 addresses — however 🚨 they must both be of the same type. no mixing. that's the rule, fr fr.

🦋 OPTIONS 🦋

  • -t millisecs — if no answer has been obtained within millisecs milliseconds, s6-ident-client will exit 99 with an error message 😭. by default, millisecs is 0, which means no time limit — so it'll just wait there forever like a loyal little ghost 👻
⚠️ heads up: -t is your only option, and 0 (the default) means it will literally never time out. if you're the impatient type, set a number. i'm just saying 💀
