Unhappy dhcpd problems... dynamic and static leases present

Hello guys. I need some help.
In my network I have set up a dhcp server on freebsd 6.3.

But I have some troubles. Here is message log:
Code:
May 16 15:49:59 netis0 dhcpd: Dynamic and static leases present for 192.168.0.144.
May 16 15:49:59 netis0 dhcpd: Remove host declaration vlado or remove 192.168.0.144
May 16 15:49:59 netis0 dhcpd: from the dynamic address pool for 192.168.0/24
May 16 15:50:02 netis0 dhcpd: Dynamic and static leases present for 192.168.0.144.
May 16 15:50:02 netis0 dhcpd: Remove host declaration vlado or remove 192.168.0.144
May 16 15:50:02 netis0 dhcpd: from the dynamic address pool for 192.168.0/24
Here is its conf file
Code:
authoritative;
option subnet-mask 255.255.255.0;
option routers 192.168.0.2;
option ntp-servers 192.168.0.2;
option domain-name "pulsar.bg";
option broadcast-address 192.168.0.255;
option domain-name-servers 192.168.0.2;
option netbios-name-servers 192.168.0.2;
option netbios-node-type 8;
default-lease-time 259200;
max-lease-time 259200;
ddns-update-style none;

subnet 192.168.0.0 netmask 255.255.255.0 {

    #uknown
    pool {
        allow unknown-clients;
        deny known-clients;
        range 192.168.0.101 192.168.0.199;
    }

    #known - here I'll put hosts
    group {
        deny unknown-clients;
        host geopc {
            hardware ethernet  00:30:18:A8:06:0D;
            fixed-address 192.168.0.60;}

        host jazz {
            hardware ethernet 00:1A:4D:5C:9F:7F;
            fixed-address 192.168.0.58;}

        host vlado {
            hardware ethernet 00:1A:4D:5B:86:0B;
            fixed-address 192.168.0.144;}

        host ico {
            hardware ethernet 00:18:F3:C7:4E:14;
            fixed-address 192.168.0.155;}

    } #end of group
} #end of subnet
for hosts in blue I never get warnings, they are out of my range definition,
but for those in red I get warnings in message log.

I have declared deny known-clients but it doesnt matter...
Need help

Depending on how full your network is, I'd recommend changing the IP addresses so that they are not in the DHCP pool. Or change the DHCP pool so it doesn't cover the static IP's.

Code:
pool {
        allow unknown-clients;
        deny known-clients;
        range 192.168.0.101 192.168.0.143;
        range 192.168.0.145 192.168.0.154;
        range 192.168.0.156 192.168.0.199;
       }
Now stop and start dhcpd again:

edit: !!!ooops i'll try upper, in time of my post i havent seen the preveous!!!

I wanted to do it without changing theese hosts, because their IPs are involved in other things...

I dont have many pcs on my network .. ~30 currently.

Actually I avoid this warning when I define the same subnet twice ... like this:
Code:
...
subnet 192.168.0.0 netmask 255.255.255.0 {
    range 192.168.0.101 192.168.0.199;
}


subnet 192.168.0.0 netmask 255.255.255.0 {
   deny unknown-clients;

same hosts..... blablabla

}
but I believe this is incorect too because on dhcpd daemon startup i get these warnings:
Code:
May 16 16:38:52 netis0 dhcpd: Warning: subnet 192.168.0.0/24 overlaps subnet 192.168.0.0/24
May 16 16:38:52 netis0 dhcpd: WARNING: Host declarations are global.  They are not limited to the scope you declared them in.

        range 192.168.0.156 192.168.0.199;
       }
Now stop and start dhcpd again:
Strange ... it didnt help:

Code:
May 16 16:46:14 netis0 dhcpd: Dynamic and static leases present for 192.168.0.144.
May 16 16:46:14 netis0 dhcpd: Remove host declaration vlado or remove 192.168.0.144
May 16 16:46:14 netis0 dhcpd: from the dynamic address pool for 192.168.0/24
May 16 16:46:16 netis0 dhcpd: Dynamic and static leases present for 192.168.0.144.
May 16 16:46:16 netis0 dhcpd: Remove host declaration vlado or remove 192.168.0.144
May 16 16:46:16 netis0 dhcpd: from the dynamic address pool for 192.168.0/24
EDIT: stupid me... I have been editing wrong file (dhcpd.conf-backup)
now it works with definied multiple ranges excluding fixed addressess

Edit: So does it work? Otherwise, try the following configuration:

Code:
subnet 192.168.0.0 netmask 255.255.255.0 {
        range 192.168.0.101 192.168.0.143;
        range 192.168.0.145 192.168.0.154;
        range 192.168.0.156 192.168.0.199;
}

        host geopc {
            hardware ethernet  00:30:18:A8:06:0D;
            fixed-address 192.168.0.60;}

        host jazz {
            hardware ethernet 00:1A:4D:5C:9F:7F;
            fixed-address 192.168.0.58;}

        host vlado {
            hardware ethernet 00:1A:4D:5B:86:0B;
            fixed-address 192.168.0.144;}

        host ico {
            hardware ethernet 00:18:F3:C7:4E:14;
            fixed-address 192.168.0.155;}

Default Another dhcpd question :)

Now one more thing ... is it possible to assign two ip addressess with differrent netmask to one host???

host geopc need two ip addresses - local and real
192.168.0.60 with mask 255.255.255.0
and
212.72.201.xx with mask 255.255.255.240 (28bits).
Currently this (i am sitting on it) is winxp machine with manually assigned ip adressess.
