I would like to ask question about my last work with Ethereal. I'm trying
to listen to a server which send broadcast message on a particular port.
Since I failed to do so, then I brought up Ethereal to see what was
actually happening. I found out that the server did send broadcast message
(dest. address ff:ff:ff:ff:ff:ff) but the IP address turned out to be
192.9.204.0. The host id is zero instead of ff(255) as I expected. Is this
the reason I can't listen to the UDP broadcast send by the server ?.


It might be.
0's rather than 1's in broadcast IP addresses is a *really really really really really really really really really* ancient convention. You might want to ask whoever manages that server why it's sending broadcasts to 192.9.204.0 rather than 192.9.204.255.
