rated 0 times [ 5] [ 0] / answers: 1 / hits: 6882 / 2 Years ago, fri, december 17, 2021, 5:48:19

I have setup-ed a PXE boot server for installing ubuntu via network. Currently i am using hosts mac address to install the ubuntu operating system. I would like to enable the DHCP server in all the subnets for example 172.29.34.0/24 172.29.36.0/24 etc.. instead of using its mac address. Please find my current configuration below,

DHCP Server Configuration:

allow booting;

allow bootp;

subnet 172.29.32.0 netmask 255.255.255.0 {

    range 172.29.32.20 172.29.32.200;

    option broadcast-address 172.29.1.255;

    option routers 172.29.32.1;

}

group {

    next-server 172.29.32.9;

    filename "/pxelinux.0";

    host webppc {

        hardware ethernet BC:30:5B:C3:23:69;

        option host-name  "webppc";

    }

}

I can't guarantee it will work, but you could specify the options per subnet and not by group (though you'll lose assignment of the hostname - that's to be expected if you don't have a unique way (i.e. MAC) of identifying each system).

allow booting;

allow bootp;

subnet 172.29.32.0 netmask 255.255.255.0 {

    next-server 172.29.32.9;

    filename "/pxelinux.0";



    range 172.29.32.20 172.29.32.200;

    option broadcast-address 172.29.32.255;

    option routers 172.29.32.1;

}

#Repeat this block for each subnet

subnet 172.29.34.0 netmask 255.255.255.0 {

    next-server 172.29.32.9; #Note this is on another subnet.

    filename "/pxelinux.0";



    range 172.29.34.20 172.29.34.200;

    option broadcast-address 172.29.34.255;

    option routers 172.29.34.1;

}
