Problems with Net::Ping

Hello.
I’m trying to make a small program to ping an IP through TCP/ICMP but
when I run it I get an error.
D:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/net-ping-1.5.2/lib/net/ping/ping.rb:80:in
ping': no host specified (Argume ntError) from D:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/net-ping-1.5.2/lib/net/ping/tcp.rb:38:inping’
from png.rb:50:in do_ping_tcp' from png.rb:19:ininitialize’
from png.rb:61:in new' from png.rb:61:in
The snip of code which ping works fine if its alone but something gets
messy with the rest of the code and I just don’t know what is it. Any
ideas?

require ‘rubygems’
require ‘net/ping’
include Net

class Ping
def initialize(*argv)
@argv = argv

if  @argv[0]=="help" || [email protected][0]
  send :help
end
if [email protected][1]
  @argv[1]="tcp"
end
# swap with case() later
if @argv[1] == "tcp"
  send :do_ping_tcp
elsif @argv[1] == "icmp"
  send :do_ping_icmp
end

end

def repeat_every(interval)
loop do
start_time = Time.now
yield
elapsed = Time.now - start_time
sleep([interval - elapsed, 0].max)
end
end

def help
puts <<-help
Commands:
help
end

def do_ping_tcp
Net::Ping::TCP.econnrefused = true
result=Net::Ping::TCP.new(‘192.168.1.1’,80)
if result.ping?
puts “alive…”
else
puts “dead…”
end

end

def do_ping_icmp
end
end
ping = Ping.new(*ARGV)

Fixed.
It was Include Net. Some kind of interference with the Net module
initialization maybe?
