Hi all, I am trying to set up a dhcp server, without much success. The previous server worked fine. I more or less duplicated that setup. The situation: - LM 8.0 box, with three ethernet interfaces. eth0 Link encap:Ethernet HWaddr 48:54:E8:2B:7E:81 inet addr:123.45.123.210 Bcast:123.45.123.223 Mask:255.255.255.240 eth1 Link encap:Ethernet HWaddr 00:50:8B:E1:C5:45 inet addr:10.0.0.254 Bcast:10.0.0.255 Mask:255.255.255.0 eth2 Link encap:Ethernet HWaddr 00:50:8B:E1:C5:44 inet addr:10.0.2.254 Bcast:10.0.2.255 Mask:255.255.255.0 I want to serve DHCP requests on all three networks. Only 10.0.0.0/24 has (some) windows boxes on it. So I added the following route: route add --host 255.255.255.255 dev eth1 Created a proper dhcpd config file (which used to work on another server with a similar role:): # dhcpd.conf # # option definitions common to all supported networks... option domain-name "XXXXXXX.com"; option subnet-mask 255.255.255.0; default-lease-time 600000; max-lease-time 6000000; subnet 10.0.0.0 netmask 255.255.255.0 { option broadcast-address 10.0.0.255; option routers 10.0.0.254; option domain-name-servers 10.0.0.254; range 10.0.0.130 10.0.0.200; host printer.intra.XXXXXXX.com { hardware ethernet 00:10:83:F4:6A:37; fixed-address 10.0.0.10; } host tesla.intra.XXXXXXX.com { hardware ethernet 00:60:b0:29:fc:3a; fixed-address 10.0.0.101; } host spock.intra.XXXXXXX.com { hardware ethernet 00:50:fc:09:6f:0b; fixed-address 10.0.0.102; } host vanderheijden.intra.XXXXXXX.com { hardware ethernet 00:10:a4:92:73:b5; fixed-address 10.0.0.103; } host zuse.intra.XXXXXXX.com { hardware ethernet 00:10:a4:92:79:32; fixed-address 10.0.0.104; } host planck.intra.XXXXXXX.com { hardware ethernet 00:d0:59:0d:b1:01; fixed-address 10.0.0.105; } host firewall.XXXXXXX.com { hardware ethernet 00:50:8b:e1:c5:45; fixed-address 10.0.0.106; } } subnet 10.0.2.0 netmask 255.255.255.0 { range 10.0.2.135 10.0.2.200; option broadcast-address 10.0.2.255; option routers 10.0.2.254; option domain-name-servers 10.0.2.254; host gauss.dmz.XXXXXXX.com { hardware ethernet 00:20:af:b6:dc:1a; fixed-address 10.0.2.100;} host goedel.dmz.XXXXXXX.com { hardware ethernet 00:60:b0:29:fc:55; fixed-address 10.0.2.103; } } subnet 123.45.123.208 netmask 255.255.255.240 { range 123.45.123.220 123.45.123.222; option broadcast-address 123.45.123.223; option routers 123.45.123.209; option domain-name-servers 123.45.123.210; } ### End dhcpd.conf ### starting the dhcp deamon I get the following in my log: May 30 13:09:52 firewall dhcpd: Internet Software Consortium DHCP Server 2.0pl5 May 30 13:09:52 firewall dhcpd: Copyright 1995, 1996, 1997, 1998, 1999 The Internet Software Consortium.
