Hello
I am an administrator network and I must install a DHCP server.
I started one but it allows a IP to workstation by the last range's IP.
That is not normal.
Here the config network used :
the IP workstations : 192.168.220.1 to 192.168.222.254 with a net mask 255.255.252.0.
My distribution is Redhat Enterprise 3, DHCP 3.0pl2
My dhcpd.conf :

ddns-update-style ad-hoc;
subnet 192.168.220.0 netmask 255.255.252.0{
option domain-name "exempletest.lan";
option routers 192.168.223.254;
option domain-name-servers 192.168.223.254;
default-lease-time 604800;
max-lease-time 604800;
range 192.168.220.1 192.168.222.254;
}

The first wks connected obtain the ip 192.168.222.254 but I'd like it to obtain 192.168.220.1

Help me please

This is a big shot in the dark since I don't really have a clue how to set up a DHCP server in linux but why don't you try changing"

range 192.168.220.1 192.168.222.254
to:
range 192.168.222.254 192.168.220.1
?

I'd try that just for the heck of it.

still done

another suggest ?

thanx

It might have to do with using a class B mask with a class C address. Is there a reason for this or can you just use 255.255.255.0 as your mask? You can try it to see if it behaves as expected. Then you will at least know what direction to take.

when i try with a mask 255.255.255.0,
I have a error on the dhcp start. It don't start.

I have tried 4 different range configs and all 4 configs asign the highest address first, so it seems to be in the program itself.

That's really odd. Surely there's a setting to change that. Although I can't see where it really matters although it's confusing.

Is this an error in my configuration dhcpd.conf or my program dhcpd ?
Because my configuration dhcpd.conf seems good.

Help me please

You're being pretty vague as to what is actually wrong.... you say i allocates an address within the given range... so what's the problem? it's *not* meant to give them out in any particular order.. seems like it's doing exactly what you're asking of it.

the problem is : for the firts wks connected, my dhcp assign the last ip of the range.ex: 192.168.222.254 and not the 192.168.220.1.
There is a problem.
