having a program start upon network starting

[Nick Gawronski]

Hi, I am running the dns2go program and was wondering how I can configure
debian 3.1 sarge so when the network interface starts on boot time for my
local networking loopback and ether net for my dsl the dns2go client
starts automatically.  it is currently only started when I login as root
and start it manually.  Also, with the 2.6.17 speakup kernel I get beeps
from the PC speaker everytime pine goes to a new line or when I press
backspace, how do I turn these off and where in 2.6.17 in /proc does the
kernel store it's contents of .config file?
