Subject: Timeout error?


Hi ..

I have the following code:


  def alive?(host,port)
    ok = false
    begin
        Timeout::timeout(30) {
            begin
                t = TCPSocket.new(host,port)
                t.close
                ok = true
            rescue Exception => e
                @exception = e
            end
        }
     rescue Timeout::Error => e
         @exception = e
     end
     return ok
  end

In a known failure case, TCPSocket will fail (no host connectivity).  
This will cause timeout() to trigger an exception that will get caught by 
the Timeout::Error handler.  Right? 

However,

13:56 (hobbes)$ ruby foo.rb 
Exception `Errno::ETIMEDOUT' at ./bsn.rb:150 - Connection timed out - 

13:57 (hobbes)$ ruby -v
ruby 1.8.1 (2003-12-25) [i386-cygwin]

What is the right way of handling this exception?
