2ping - A bi-directional ping utility


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.


Python 2.7 is recommended for 2ping. Python 2.6 is also supported, with the following notes:

  • The argparse module is also required.
  • Monotonic clock support is not available on Unix platforms, instead falling back to time.time() (which will likely be using gettimeofday()).

To install:

sudo python install


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:


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