fixed-address problem

Bernard Fay
Hello everyonw,

I am unable to assign fixed IP addresses to host.

I have the following configuration:

option domain-name "cts.org";
option domain-name-servers ns1.cts.org;

default-lease-time 300;
max-lease-time 1500;


subnet 192.168.99.0 netmask 255.255.255.0 {

#  range 192.168.99.201 192.168.99.250;
    option broadcast-address 192.168.99.255;
    option routers 192.168.99.1;
    option domain-name "cts.org";

  group {
    host vault {
      option host-name "vault.cts.org";
      hardware ethernet 52:af:12:cf:87:c5;
      fixed-address 192.168.98.101;
    }
  }
}


With "range 192.168.99.201 192.168.99.250;"  the host is assigned the first available IP address. If I disable "range" like in the shown configuration, the log says: "dhcpd: DHCPDISCOVER from 52:af:12:cf:87:c5 via eth1: network 192.168.99.0/24: no free leases".

This ISC DHCP 4.2.5.

What am I doing wrong?

Thanks,
Bernard

RE: fixed-address problem

Patrick Trapp
I don't see a problem with the subnet. OP just isn't using the entire pool, right?

I'm not sure what the effect of the "group" declaration is. I believe on my configurations where I'm assigning a static address, I'm just using a "host" declaration. I don't declare these hosts within the subnet declaration, either. I would be inclined to try the host declaration outside the subnet first.

RE: fixed-address problem

Your subnet clause is

subnet 192.168.99.0 netmask 255.255.255.0 {

Your fixed address is

fixed-address 192.168.98.101;

You can't service a subnet out side of the subnet in your declaration

Ah, since you called out the subnet, I looked at the subnet. Not the host address where the error appears to be. My apologies.

There's no subnet defined that contains the fixed-address, so dhcpd
can't offer that address to a client.  Perhaps you meant to allocate
'192.168.99.101', or use a different netmask?

Unrelated to the problem, option inheritance can work unexpectedly when
hosts are defined within subnets - you might find this less confusing in
future:

=-=
subnet 192.168.99.0 netmask 255.255.255.0 {
#   range 192.168.99.201 192.168.99.250;
     option broadcast-address 192.168.99.255;
     option routers 192.168.99.1;
     option domain-name "cts.org";
}

group {
     host vault {
         option host-name "vault.cts.org";
         hardware ethernet 52:af:12:cf:87:c5;
         fixed-address 192.168.98.101;
     }
}
=-=

(additionally the 'empty' group (i.e. no options defined) doesn't really
gain anything in this case, so you could move the 'host' to the outer
layer and dispense with the group entirely)

Re: fixed-address problem

Bernard Fay
I just stopped banging my head against the wall..  Yes, a ..... typo!  It should have been "fixed-address 192.168.99.101;"

Damn!

Thanks Sherman
