limiting connections for each IP

[Pere Camps <pere@casal.upc.es>]

Hi!

	Is there anyway to place an upper limit in the number of
connections from a machine? Let me explain myself, I want to limit the
number of tcp connections from a machine to my server in order to limit
possible DoS attacks from a single IP.

	How can I do that? 

	TIA!	

	I'm using Debian 2.1 with xinetd and kernel 2.0.37.
