Help me to configure my dhcp server!

I want to configure a dhcp server which assign ips, dns, gateway and subnet mask to dhcp clients. What I want to do is assign to each client the following ips as requiered

xxx.xx.xx.210
xxx.xx.xx.212
xxx.xx.xx.214
xxx.xx.xx.216
xxx.xx.xx.218

but I can only use these and no mid ips like xxx.xx.xx.211 or internet will be down for the computer with that ip

Should I put the IPs in the SLP directory agent IPs under webmin?

And it also says that I haven't defined a subnet or shared network or hosts
Are they neccesary?

The current dhcpd.conf I managed to do is

Code:

---

option broadcast-address 172.16.40.209;
option slp-directory-agent true 172.16.40.212, 172.16.40.214, 172.16.40.216, 172.16.40.218;

option domain-name-servers 201.219.5.186, 201.219.6.242;

option subnet-mask 255.255.255.248;
default-lease-time 1200;
max-lease-time 7200;

Just figured out how to configure the dhcp through webmin but now when I try to start dhcpd it say that there's an error (bug in webmin?)

Code:

---

/etc/dhcpd.conf line 2: no option named slp-directory-agent
option slp-directory-agent true
      ^
Configuration file errors encountered -- exiting
exiting.

I myself am learning DHCP as you are, but I am getting a little bit further than you, I actually have mine talking to the other routers on my network in a similiar set up to yours... I am working from the copy i made from the setup... Looks like this:

Quote:

---

ddns-update-style interim;
ignore client-updates;

subnet 192.168.1.0 netmask 255.255.255.0 {

# --- default gateway
option routers 192.168.1.1;
option broadcast-address 192.168.1.255;
option subnet-mask 255.255.255.0;

option nis-domain "NixBox";
option domain-name "NixBox";
option domain-name-servers 192.168.1.1;

option time-offset -18000; # Eastern Standard Time
# option ntp-servers 192.168.1.1;
# option netbios-name-servers 192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
# option netbios-node-type 2;

range dynamic-bootp 192.168.1.1 192.168.1.128;
default-lease-time 21600;
max-lease-time 43200;

# we want the nameserver to appear at a fixed address
host ns {
next-server NixBox;
hardware ethernet 00:40:05:08:89:CA;
fixed-address 192.168.1.1;
}
}

I have noticed after playing with it, as wikipedia says too, you have declare subsets of each of the computers your are trying to talk to.... Hope something in there seems right.

The only thing I don't clearly understand is probably the most basic that is this

Code:

---

ddns-update-style interim;
ignore client-updates;

subnet 192.168.1.0 netmask 255.255.255.0 {    <===HERE====

# --- default gateway
option routers 192.168.1.1;
option broadcast-address 192.168.1.255;
option subnet-mask 255.255.255.0;
