I am trying to access a .net page via my ruby app and pass it a couple  
parameters. Every thing I have tried has resulted in this Bad file  
descriptor, I am wondering if it is something wrong with my  
configuration, not the code. Here is the code that is causing  
problems:

Net::HTTP.version\_1\_2  
Net::HTTP.start(‘[www.url.com](http://www.url.com)’, 80) {  
|http|  
response =  
http.post(‘/DoSomething.aspx’,  
‘id=#{params[:id]}&path=#{params[:imagerecord]}’,  
{ ‘Content-Type’ =\> ‘application/x-www-form-  
urlencoded’ })  
puts response.body()  
}

Here is the error I get:

Errno::EBADF (Bad file descriptor - connect(2)):  
c:/ruby/lib/ruby/1.8/net/http.rb:560:in `initialize' c:/ruby/lib/ruby/1.8/net/http.rb:560:in `connect’  
c:/ruby/lib/ruby/1.8/timeout.rb:48:in `timeout' c:/ruby/lib/ruby/1.8/timeout.rb:76:in `timeout’  
c:/ruby/lib/ruby/1.8/net/http.rb:560:in `connect' c:/ruby/lib/ruby/1.8/net/http.rb:553:in `do\_start’  
c:/ruby/lib/ruby/1.8/net/http.rb:542:in `start' c:/ruby/lib/ruby/1.8/net/http.rb:440:in `start’

I am on Windows 2003 serer with Ruby 1.8.4 and Mongrel. Any help would  
be greatly appreciated.

Line 560 of net/http.rb is this:

s = timeout(@open\_timeout) { TCPSocket.open(conn\_address(),  
conn\_port()) }

What happens when you run this standalone snippet?

require ‘socket’  
require ‘timeout’

s = Timeout.timeout(5){  
TCPSocket.open(url, 80)  
}

p s

s.close

Dan,

Thanks. Here is the error I get when executing the above code:

Timeout::Error (execution expired):  
c:/ruby/lib/ruby/1.8/timeout.rb:54:in `open' c:/ruby/lib/ruby/1.8/timeout.rb:56:in `timeout’

I know it’s a valid URL. The page I am trying to access is sitting on  
the same box as my rails app.

That’s peculiar. Firewall or proxy issue perhaps? Maybe you need  
rubysspi?

[http://rubyforge.org/projects/rubysspi/](http://rubyforge.org/projects/rubysspi/)

Otherwise, I’m at a loss.
