Thanks, Patrick. That makes it a bit harder to manage from a remote
machine. I'll have to be very careful with that. I'll try to figure
out the implications of the default classification and send more email
if I can't get it.
So I reordered the commands and changed them around. It looks like I am
either doing something strange or I have found a bug. When I execute
the following script, the UDP traffic on port 1234 continues for a few
seconds and then stops. When I examine the tc data, it shows no change
in the periods or amount of bytes flowing after the flow stops. I am
enclosing the command and the output.
Thanks again!
