[ts-7000] Re: udp broadcast doesn't work ?

["gcworrell" <>]

I agree that it doesn't work.  I'm trying a slightly different 
method, but I get a message saying permission is 
denied when I try to broadcast to my subnet.

I'm guessing it's a Debian configuration thing, anybody know?  Dave 
did you figure it out?
