I set /etc/dhcp/dhcp.conf (on Jan. 08 09:20) to:

lease {
  interface "eth0";
  fixed-address 192.168.1.190;
  option subnet-mask 255.255.255.0;
  option dhcp-lease-time 86400;
  option routers 192.168.1.254;
  option dhcp-message-type 5;
  option dhcp-server-identifier 192.168.1.254;
  option domain-name-servers 192.168.1.254;
  option dhcp-renewal-time 43200;
  option domain-name "lan";
  renew 6 2012/01/08 22:53:20;
  rebind 6 2012/01/08 22:53:20;
  expire 6 2012/01/08 22:53:20;
}

Makes no diff. whatsoever.

Default is disabled. Makes no diff. whatsoever.

Where does one get another DHCP server?
