history

Project history and usage

2ping is a bidirectional ping utility that uses a listener/client protocol to distinguish inbound, outbound, and undetermined packet loss.

Project history

Ryan Finnie's official project page and README describe 2ping as a Python networking diagnostic tool built around three-way pings and after-the-fact state comparison between a listener and a client. The README copyright line dates the project from 2010 through 2025, and GitHub release metadata shows the maintained 4.x series continuing into 2026.

Adoption history

The official project page lists packaging in Debian, Ubuntu, Fedora/EPEL, Arch AUR, Gentoo, and Homebrew, with Windows source installation notes. That is unusually broad for a niche network diagnostic and reflects a tool that sysadmins can install from normal OS channels when ordinary ICMP ping does not answer the direction-of-loss question.

How it is used

Typical use starts a remote listener with `2ping --listen` and runs `2ping` from the near side against that listener. The project also maintains public test listeners and warns users not to abuse them, making quick one-off connectivity tests possible without first deploying both endpoints.

Why package nerds care

2ping is package-nerd useful because it is a small, mostly-stdlib Python CLI that solves a specific network debugging problem traditional ping cannot solve. Its presence across multiple distro families makes it easy to recommend in runbooks without asking operators to build custom tooling.
