Hmmm, what platform are you running it from? Just ran in from Mac OS 10.5.8
with Ruby 1.8.7 and it ran fine (ruby 1.8.7 (2009-06-12 patchlevel 174)
[i686-darwin9.7.0]).

Maybe a tcp stack implementation difference between platforms? I did notice
you had some addresses that have colons in them (e.g. 123456:201.92.93).
Still handled fine on my machine but maybe not on others. Anyone else?

What if you just run it from irb? I get the following under Linux:

$ irb --simple-prompt

require 'ping'

=> true

Ping.pingecho('1.1.1.1', 2, 80)

=> false

RUBY_VERSION

=> "1.8.7"

RUBY_PATCHLEVEL

=> 174

Looking at the source code for ping.rb around line 46:

    begin
      timeout(timeout) do
        s = TCPSocket.new(host, service)
        s.close
      end
    rescue Errno::ECONNREFUSED
      return true
    rescue Timeout::Error, StandardError
      return false
    end

I don't understand why the exception isn't being caught. You could try
adding:

    rescue Exception => e
      $stderr.puts "Actual exception: #{e.class.inspect}"

just before the 'end', see if that shows anything.

Incidentally, if you're trying to ping lots of hosts, 'multiping' may be
a better tool. It can ping them all in parallel, and you can run it from
ruby using IO.popen or %x{..} to collect the results.
