subnet error

[Mickael Choisnard]

Hi,
Eth1 is defined in hard on my gentoo. I don't know why dhcpd make a warning with
eth0. I use a dhcp-client to get ip.
When i add subnet 62.35.125.14 netmask 255.255.255.0 { not authorative; }
I have this error :
Feb 28 21:26:26 titi dhcpd: /etc/dhcp/dhcpd.conf line 4: subnet 62.147.195.246
netmask 255.255.255.0: bad subnet number/mask combination.
Feb 28 21:26:26 titi dhcpd: subnet 62.35.125.14 netmask 255.255.255.0
Feb 28 21:26:26 titi dhcpd:                                           ^
Feb 28 21:26:26 titi dhcpd: Configuration file errors encountered -- exiting
Feb 28 21:26:26 titi dhcpd: exiting.

I used also 255.0.0.0. I have the same error !!!
