Subject: Pingecho, causing SocketError.

I have a strange problem. The script posted at the end off this post is
not working properly on one of my computers. If I run it alone, it works
just fine, but not inside one of my scripts. The script works fine on
all other computers that I have tested. Do anyone now what could be
causing this.

//Walle

It raises the following exception:
"Exception `SocketError' at ./Handlers/ServerStatusHandler.rb:125 -
getaddrinfo: Name or service not known"'

The script:
def pingecho(host, timeout=5, service="echo")
    begin
      timeout(timeout) do
  s = TCPSocket.new(host, service)
  s.close
      end
    rescue Errno::ECONNREFUSED
      return true
    rescue Timeout::Error, StandardError
      return false
    end
    return true
  end
