dhcpd and two network interfaces

Hi!
I would like to set up dhcpd to use eth1 and eth2 (eth0 is in use for xdsl)

the config(s) should looks liks this:
#eth1 config
ddns-update-style ad-hoc;
default-lease-time 1200;
max-lease-time 9200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
option domain-name-servers 192.168.1.1, 1.2.3.4ISPDNSSERVER;
option domain-name "workgroup.local";
option netbios-name-servers 192.168.1.1;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.100 192.168.1.199;
}

#eth2 config
ddns-update-style ad-hoc;
default-lease-time 1200;
max-lease-time 9200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.2.255;
option routers 192.168.2.1;
option domain-name-servers 192.168.2.1, 1.2.3.4ISPDNSSERVER;
option domain-name "workgroup.local";
option netbios-name-servers 192.168.2.1;
subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.100 192.168.2.199;
}

but i dont know how to set it up properly :(
i couldnt find anything on google or so either...
has anyone tried to use dhcpd with 2 nics yet? any tutorials, guides or
howtos?

the best doc I know of is just the man page for dhcpd.conf

Try putting the global options (that are the same for both subnets) first,
and moving your subnet specific options inside the brackets for each subnet:

ddns-update-style
default-lease-time
max-lease-time
etc....

subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
etc...
}

subnet 192.168.2.0 netmask 255.255.255.0 {
option routers 192.168.2.1;
etc...
}

thats a real trouble ..... even if you run dhcpd with 2 interfaces ...


#/etc/rc.d/init.d/dhcpd eth1
it will run ....

then ....
#/etc/rc.d/init.d/dhcpd eth2
it will complain that there's another dhcpd running ... there's
something missing/should be done in pid file handling .... i guess.

Try to make one nic as fixed ip address and make one as dhcp client
that will get the ip address from the the

eg. Make eth0 as dhcp nic that will listen to dhcpd.

and make eth1 will take ip lease from eth0
