Subject: Catching exceptions


Can someone please let me know what I am doing wrong here?
I can't seem to catch the exception ..


$ cat test.rb
require 'socket'

def alive(host, port=80)
    s = "host=#{host} : "
    t = TCPSocket.new(host, port)
    begin
   s << " made it!"
    rescue Errno::ETIMEDOUT
          s << " Timed out -- node unreachable"
    rescue Exception => e
          s << " exception = #{e}"
    ensure
          t.close
    end
    return s
end
puts alive('10.10.10.2')

$ ruby test.rb
test.rb:6:in `initialize': Operation timed out - connect(2) (Errno::ETIMEDOUT)
        from test.rb:6:in `new'
        from test.rb:6:in `alive'
        from test.rb:19
