🛠️ tcping-rs: Rust (rs) TCP Ping (tcping) Utility for Port Reachability.
| Feature | Description |
|---|---|
| Pure Rust | No runtime dependencies, produces a tiny static binary |
| ICMP-free | Works where traditional ping is blocked; relies solely on TCP handshake |
| Cross-platform | Linux, macOS, Windows, *BSD, and any Tier-1 Rust target |
| Continuous / Burst modes | -t for continuous, -c for specific count, plus -e early exit |
| Machine-readable output | JSON / CSV via -o, ideal for scripts & monitoring |
| Jitter stats | -j flag shows latency variance (p95) |
| Docker image | Multi-arch (amd64 / arm64) for pipelines or Kubernetes Jobs |

Run tcping-rs using the Docker image:
docker run --rm docker.io/lvillis/tcping:latest <host:port> [options]
This tool allows you to measure the latency to a server using TCP. It is built with Rust and uses the clap library for command line argument parsing.
