Possible DoS attack?

Port 113 is the identd service, which allows tcp connections from clients
(which are usually themselves servers of some service) to identify the
originator of a request.  This sounds to me like it could be consistent
with a DoS attack.

To echo a sentiment of my esteemed colleague, "Why can't everyone just be
nice?!?!"
