[En-Nut-Discussion] No DNS addresses with DHCP

[Jean Pierre Gauthier]

Hi Michel,
There are ONLY 2 DHCP messages (sniffed here)during boot :

1) Ethernut -> server : DHCP request : discover
... Some ARP/ICMP exchanges...
2) server -> Ethernut : DHCP reply : offer (after 2 seconds)

Timeouts tried 5... 30s : no changes.
Ethernut is well registered by the server with IP/MAC/hostname association.

Hi,

Apparently your Ethernut doesn't receive a final ACK from your DHCP server,
otherwise the NutDnsConfig2 call should have been executed. Or maybe the
timeout that the DHCP client waits is too short.

Hello,
I have a small problem with DHCP call and the returned DNS addresses. 

NutDhcpIfConfig returns good values (allocated address, mask, gateway addr)
and status, but DNS addresses are not set. 
DHCP ParseReply routine well and always detects primary/secondary DNS
address, but NutDnsConfig2 isn't called later so that doc.doc_ip1 and
doc.doc_ip2 remain null in DNS structures. 
(if I force an horribilis NutDnsConfig2 call in ParseReply with detected DNS
addresses as parameters, all become Ok)

DHCP server is a classical SMC7004VBR WAN gateway and sends one and its own
IP address as DNS server. 

Any idea?

Jean Pierre
