TCPING is a lightweight command-line utility developed by Pouriya Jamshidi that re-imagines the classic ping diagnostic by sending TCP SYN packets instead of the customary ICMP echo requests, thereby circumventing firewall blocks that often forbid ICMP while still measuring reachability and round-trip latency to any chosen TCP port. Designed for network administrators, DevOps engineers, and security auditors who need rapid, script-friendly feedback on service availability, the tool supports simultaneous checks against multiple hosts and ports, coloring successful and failed attempts for instant visual parsing in a terminal. Beyond eye-friendly output, TCPING can serialize results in plain text, JSON, CSV, or an embedded sqlite3 database, enabling seamless integration with monitoring dashboards, log aggregators, and automated reporting pipelines. Version 2.7.1, the second public release in the 2.x line, refines connection-timeout heuristics and stabilizes JSON schema compatibility, making it safe to embed in CI/CD smoke tests or nightly cron jobs that verify critical web, mail, or database endpoints. Typical use cases include confirming that a remote web server is listening on port 443 after a certificate update, auditing a fleet of Ioable devices for unexpectedly open services, or benchmarking latency across geographically distributed load-balancers without requiring elevated privileges. The program ships as a single portable executable for Windows, requiring no installation or runtime dependencies, and can be invoked in PowerShell, CMD, or any terminal emulator that understands standard UTF-8 color codes. TCPING is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
