Re: bin/52403: dhclient program doesn't send dhcp-client-identifier set in /etc/dhclient.conf

[Mickael Viey <m.viey%wanadoo.fr@localhost>]

The dhcpclient works correctly now. I succeed to send an identifier to 
DHCP server.


But now I have a problem dhclient run at boot time but doesn't get any 
information from the DHCP server which log nothing during BSD boot.

So ntpdate send an error when booting because there is not 
domain-name-servers set in resolv.conf.

However if i run the rc.d script after boot I get an address, see the 
request in router monitoring. Bellow some transaction done just after a 
boot:

Any idea ?
