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:  
[BUG] rb\_  
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.  
Please contact the application’s support team for more information.

Windows platform specifically. Ping::TCP works perfectly.
