2ping - A bi-directional ping utility

https://www.finnie.org/software/2ping/

About

2ping is a bi-directional ping utility. It uses 3-way pings (akin to TCP SYN, SYN/ACK, ACK) and after-the-fact state comparison between a 2ping listener and a 2ping client to determine which direction packet loss occurs.

Installation

2ping requires Python 3 version 3.4 or higher.

To install:

sudo python3 setup.py install

Python 3 stdlib is the only requirement for base functionality, but 2ping can utilize the following modules if available:

Usage

Please see the 2ping manpage for invocation options, but in short, start a listener on the far end:

2ping --listen

And run 2ping on the near end, connecting to the far end listener:

2ping $LISTENER

Where "$LISTENER" is the name or IP address of the listener.
