Dummynet is a tool that has been a BSD staple for a long time now. Originally it was developed to allow for simulation of various network configurations and scenarios. With dummynet you can do fun things like simulate a ASDL line that was suffering 70% packet loss, or take a trip back in time to a 300bps modem connection. (I used a 300 baud modem from 1984 to 1992!) dummynet is still often used for tasks like this, but sysadmins are crafty people and had the idea to commandeer these network simulation tools into a way to control the packets flowing through a server. You can do this for all packets or you can be selective, guaranteeing one protocol or service receives a greater --or lesser-- share of the managed bandwidth than the others. This is called traffic shaping. <div class="gmail_quote">On Tue, Mar 11, 2008 at 3:28 AM, (``-_-ДД) -- Fernando <<a href="mailto:ubuntu@bugabundo.net">ubuntu@bugabundo.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On Sunday 09 March 2008 07:18:01 Michael R.
