Subject: thread exec

Hi List,

I've a problem with threads using exec, system or similar:

...
...
domains = ['www.bim.com','www.bum.com','www.bam.com']
...
def check (host,domain,timeout)
  puts "checking... #{host} -> #{domain}"
  timeout(timeout) do
   begin
    `/usr/bin/nslookup #{domain} #{host}`
   rescue Timeout::Error
   end
  end
end

iplist.each { |host|
 threads << Thread.new(host) { |host|
  domains.each do |domain|
   check(host,domain,timeout)
  end
 }
}
...

With this code will be check only the first domains of three. Why?

checking... 127.0.0.1 -> www.bim.com
checking... 127.0.0.2 -> www.bim.com
checking... 127.0.0.3 -> www.bim.com
checking... 127.0.0.4 -> www.bim.com
checking... 127.0.0.5 -> www.bim.com
checking... 127.0.0.6 -> www.bim.com
checking... 127.0.0.7 -> www.bim.com
checking... 127.0.0.8 -> www.bim.com
checking... 127.0.0.9 -> www.bim.com

Thank you very much,
Al
