RKIK v0.6.0 – A stateless NTP inspection CLI (Rust, async, no root)

Hacker News

Hi HN, I've just released version 0.6.0 of RKIK (Rusty Klock Inspection Kit), a command-line tool for inspecting NTP servers. It's designed for passive, read-only analysis of NTP offset and delay — much like `dig` is to DNS or `ping` is to ICMP. Why? In environments where you can't or don't want to run `chronyd`, `ntpd`, or `ntpdate` (e.g. containers, sandboxes, CI), there's no lightweight way to check if your system is drifting from trusted NTP servers. RKIK fills that gap: - Query one or more NTP servers - Compare offsets between multiple servers asynchronously (thanks to Tokio) - Output in JSON or readable text - Works with both IPv4 and IPv6 - No root, no sync, no config, no daemon - Written in Rust, single binary (~2MB) Example usage: rkik pool.ntp.org rkik --compare time.google.com time.cloudflare.com rkik -C ntp1 ntp2 ntp3 --format json Example output: Server: time.google.com Offset: -1.203 ms RTT: 2.320 ms RefID: GOOG Stratum: 1 Why Rust? It compiles to a small static binary, has great async support via Tokio, and excellent libraries for terminal UI and NTP packet decoding.
