Hello all -

I am running into a curious issue with Net-Ping on Windows (XP Pro SP2
with administrator privileges).  Attempting
Net::Ping::ICMP.new(host).ping fails.

Here's the code (which executes flawlessly under OS X 10.5 using sudo):
========================

require 'rubygems'
require 'net/ping'
include Net

hostlist = "192.168.1.1"

if Net::Ping::ICMP.new(hostlist).ping
  puts "alive"
else
  puts "down"
end



Here's the error message:
=========================


D:\Documents and Settings\220022671.USERSAPPLGE>ruby icmpping.rb
c:/ruby/lib/ruby/gems/1.8/gems/net-ping-1.2.3/lib/net/ping/icmp.rb:65:

sys_fail(socket(2)) - errno == 0
ruby 1.8.6 (2007-09-24) [i386-mswin32]


This application has requested the Runtime to terminate it in an unusual
way.

Seeing as how the application works in OS X and not in Windows it leads
me to think there's an issue with the Ping::ICMP implementation on the
Windows platform specifically.  Ping::TCP works perfectly.
