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

the duration function is not working for me, any ideas why

I was trying to rewrite this program so that it asks for the IP address to ping but have not had any luck. Can you help me out? I am new to programming and Ruby is the first language I'm studying. Thanks!

I changed line 3 to: @icmp = Net::Ping::ICMP.new(ARGV[0]) and now I can type, "ruby ping.rb 8.8.8.8" and it will ping 8.8.8.8 or whatever URL or IP address you type in. I wanted to actually use get.chomp with an "Enter the IP address or URL" dialog, but this works for now.

I took some inspiration from this and made some adjustments for my own purposes. Hopefully it's helpful.

@john916, you're probably looking for
print "Hostname: "
host = STDIN.gets.chomp

Having same issue @johngrindal described: the duration function not working. Does anyone know why? I'm on Windows.

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