Simple ICMP Ping script in Ruby. Using the Net-Ping gem https://github.com/djberg96/net-ping

ping.rb

require 'net/ping'

@icmp = Net::Ping::ICMP.new('142.40.81.34')
rtary = []
pingfails = 0
repeat = 5
puts 'starting to ping'
(1..repeat).each do
  
	if @icmp.ping
		rtary << @icmp.duration
		puts "host replied in #{@icmp.duration}"
	else
		pingfails += 1
		puts "timeout"
	end
end
avg = rtary.inject(0) {|sum, i| sum + i}/(repeat - pingfails)
puts "Average round-trip is #{avg}\n"
puts "#{pingfails} packets were droped"

pinger.rb

run ping.rb

Ok I figured it out: I was calling @my_ping.duration before actually executing the ping with @my_ping.ping 😁
