Hi Kalkoul,

Lease times of only one hour might indicate that your failover peers are not
in "normal state". The leases are being given the "mclt" time which in your
config (and most others) is 1hour.

Look in your dhcpd.leases file for the failover-peer-state. Below is an
example of what you should see.

failover peer "bup-pxy" state {
  my state normal at 6 2003/09/06 09:50:40;
  partner state normal at 5 2002/06/28 12:45:49;
}

There can be several reasons why the peers are not in normal state. In
brand-new installations it's often the system's date & time being too far
apart.

Regards Mike D.

Hi everybody,

I have some questions about dhcp server.


1. During the start of dhcp server, I could see it starts correctly , and
there is this line :

...Total free 8 backup 8 lts 0

It means that I have a pool of 16 Ip of wich 8free and 8 in backup. Why it
takes the half of my range to distribute in backup? that it happens when
addresses are in backup ?

Whats does it means Lts ?

2., I know that it is necessary to indicated at least one interface which is
logical, but I have two network interfaces on my dhcp server , how to make
for say it to listen on both ?


3.	it seems that the site of the options max-lease-time and
default-lease-time are not taken into account below. The lease time on PCs
is one heure. I Tried to put it at the first line os the dhcpd;conf but it
is similar. Where is the good place to put these options.


This is my dhcp.conf with failover on the primary.

  #server-identifier hulk.mk.strg;
        option domain-name "mk.strg";
        option domain-name-servers 175.25.0.2, 175.25.0.1 ;

        if substring (option dhcp-client-identifier, 0, 3) =3D "RAS" {
              deny booting;
        }

        #omapi-port 7911;
        ddns-update-style interim;
        ddns-updates on;
        ignore client-updates;
        update-static-leases on;
        authoritative;
