pingo

README

pingo

This is a naive implementation of the ping command using Go's x/net/icmp package. This is a learning/experimentation exercise.

Building

A make build should build a binary called pingo.

Running

A make run should build and run the program. Currently, these are the parameters you can change when running pingo:

Usage: ./pingo host
  -c uint
        number of packets to be sent and received; if not specified, ./pingo will send requests until interrupted
  -s uint
        number of data bytes to be sent in each request (default 56)
  -t uint
        timeout in seconds for each request (default 1)

Note: You need sudo privileges in order to send ping requests, so make run uses sudo for running the binary that is built.

Acknowledgements

I've used go-fastping a lot as a reference while trying to understand how to implement ping, and a few fuctions were directly copied from it (see comments in the code) and adapted for use with my own implementation.
