Subject: manage NET HTTP errors

Hi to all,

i've done a ruby script that restart a VoIP network device. The code i s
below:

                url = URI.parse('http://192.168.0.111/dologin.htm')
                response=Net::HTTP.start(url.host, url.port) {|http|
          req = Net::HTTP::Post.new(url.path)
    req.set_form_data({'P2'=>'password', 'Login' => 'login', 'gnkey' =>
'0b82'}, '&')
    res=http.request(req)
    puts res
    cookie=res.get_fields('Set-Cookie')
cookie=cookie.to_s.match(/SessionId=((.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)(.))/).to_s
    req=Net::HTTP::Get.new('/rs.htm')
    req.add_field('Cookie',cookie)
    http.request(req)
  }
  case response
          when Net::HTTPSuccess     then status=1
    when Net::HTTPClientError then status=2
    when Net::HTTPServerError then status=2
    when Net::HTTPUnknownResponse then status=2
  end

I've problems to manage these errors:
when the device is not connected i get an (Errno::EHOSTUNREACH) or the
script seems freezed....
Any suggetion???
Thanks in advance

Andrea
