I am using a Linux board based on TI Sitara

and configuring the static IP, netmask and gateway by writing same in interface file from user interface (using webpage).

as I see the network configuration on console(by ifconfig command) it shows Bcast:0.0.0.0.

I did not understand how to configure Bcast address.
does it require the user entry or method to auto configure the Bcast address.

Please Guide me.


my Ubantu PC configures Bcast address itself.

e.g. my Linux PC showing
inet address:172.16.8.63 Bcast:172.16.15.255 Mask:255.255.248.0

gateway address is 172.16.15.238

The broadcast mask is made from your IP address and network Mask. All of the fixed bits in your IP address, with all of the bits turned OFF in your network mask turned ON for broadcast. It makes perfect sense in binary, and provides a mask that addresses your entire configured subnet in broadcast.

If Broadcast Address is 0.0.0.0 its whole network

All the IP Addresses covered in your Subnet Mask.

Broadcast are on 255 not 0. There seems to be something not configured correctly on your system.

Does anyone have a link to a site with ipv6 exercises/ info for Linux beginner?

Thanks
