William --

Unfortunately these limits only work on the number of simultaneous
connections, not on the bandwidth used.

Unfortunately when Y! (or similar) gets it in their head that they want to
pipeline their e-mail to our server, they fill our pipe, and render it
useless to everyone else.

What I need is a way to limit every TCP connect to only 10k a second, or
something to that affect.

Failing that, an overall bandwidth cap at the OS level would work.

Failing that, we will buy a switch/router that supports rate limiting.

I thought maybe someone on this list would know of a WBEL solution which
allows granular bandwidth control.

My "Foundation" verse:
Isa 54:17 No weapon that is formed against thee shall prosper;
and every tongue that shall rise against thee in judgment thou
shalt condemn. This is the heritage of the servants of the LORD,
and their righteousness is of me, saith the LORD.
