TCP Ping Utility

This Node.js utility provides TCP-based ping functionality, enabling users to test the availability and measure the latency of specific services on given addresses and ports. Unlike traditional ICMP `ping` tools, `tcp-ping` avoids issues with ICMP-blocked servers and offers faster results by immediately dropping connections after acceptance. It's particularly useful for verifying service-level availability rather than just general network connectivity. The package's current and only documented version is 0.1.1, indicating a very early stage of development or a project that is no longer actively maintained. Its release cadence is effectively non-existent. Key differentiators include its speed, the ability to target specific ports and services, and its resilience to ICMP filtering, making it more effective for certain server monitoring scenarios.
