AW: [En-Nut-Discussion] Sending Host name to DHCP server

[Oliver Schulz]

Hi Damian,

your choice to take confnet.cd_name as ethernut's host name is a little
bit unlucky.
What happens, if somebody has more than one ethernut in his LAN? The
last booted ethernut is the winner in dns...

Next possibility is to have a separate field in confnet structure to
store the host name. But does it make sense to relate the host name to a
device configuration?

So I suggest to have the hostname stored in confos stucture, because the
host name is a kind of global setting and should not depend on any LAN
or PPP device.
Harald, what do you think?

Cheers,
Oliver.
