[En-Nut-Discussion] No DNS addresses with DHCP, super Michel's DHCP

[Jean Pierre Gauthier]

Hi Michel,
I tested this morning  your dhcp.c . 

Congratulations! IT WORKS! I discovered the "4 steps" DHCP protocol by eth
sniffing. (discover->offer->request->ack).
NutDnsConfig2 call "Hits" : 10 / 10 DHCP tests. Reliable.
NutDhcpIfConfig call returns OK after 2 seconds instead after timeout value
with the native DHCP. 

Remark:
I'm not sure but both dhcp.c  seem to not support when dhcp task memory
context is over 0x8000. (my ethernut1.3 has 64K context ram instead 32K). 
Perhaps negative pointer test ? "if (ptr<0)..." [bad]  instead "if (ptr ==
-1)" or (!ptr) [good]?
Original dhcp freeze the system and your dhcp returns NOK.... Better but not
clear ;-)

More tests today. 

Jean Pierre

Hi Jean Pierre,

>DHCP is in sleep state. (70E1 dhcpc 64 SLP 0000 0944 70CD 492 OK )

I actually meant the state inside DHCP (REBOOTING, etc) Otherwise, try my
dhcp.c I sent to this list on 'za 18-12-2004 8:45'
