	it just sends a random udp packet so your server could be
saying it's invalidly formatted and ignoring it.  this is likely what
is happening.

	some udp based services send back an "invalid req" packet
so you'd get a "response".

	i can look at adding back in a bootp/dhcp type
request.  would you want to also specify a client-id or mac address
in the configuration file for this type of a test?  what format
of a mac address?  0123.4567.89ab or 01:23:45:67:89:ab or other?
