Ran out of IP Addresses?

[newlined]

Hello, I was making 120 something computers via Unicast and after when I started PC #121 it stopped booting into PXE. So after 3 hours trying to figure it out, I decided to redo and reinstall the entire server and it gave me another 120 uses before it stopped working again.

Is there a setting where I can change that? I don’t want to reinstall the whole thing every 120 computers.

@newlined I would suggest shorter lease times. Something like below. These values are in seconds, so you can play with them yourself.

    default-lease-time 1800;
    max-lease-time 3600;

After each of these changes, you need to restart dhcp with this command: systemctl restart dhcpd

Here is my DHCP config file. I tried to mess up with it last night but I did not know what or where to update.

@newlined Please tell us if you installed FOG to be your DHCP server as well? If so please post your DHCP config (e.g. /etc/dhcp/dhcpd.conf)
