500 points EXCELLENT

hi xeroxzerox

you can download gpxe-1.0.1-gpxe.dsk and make iso image with cd.
and you configure in clonezilla dhcp with one line as given below.

filename = "gpxelinux.0";

save the dhcp.conf file

again you take any clone of system first time boot with gpxe-1.0.1-gpxe.dsk.iso cd

it is automatic go away with clonezilla dhcp.

Our task is take the system image via clonezilla..When we configured clonezilla it by default configured dhcp server...Now i want client take ipaddress from clonezilla dhcpserver not another dhcp server......

Note:when we provide ipaddress via mac address then it take the ip address..otherwise it not grep the ip address...

Why not tell us why you have to do on Two dhcp server in same network (linux)
For what reason or application or concept only?

Expert: fmarshall replied at 2024-08-02 07:02:33

Since the address ranges overlap, how do you expect to avoid address duplication/conflict?
As above, there is likely no control over which server responds unless you go to some lengths to prevent it with firewalling.

Well the way dhcp works is that, the first DHCP server which gets the request, would respond with the IP address. You would not have control.

For a solution you either need to have vlan infrastructure or have two switches and two dhcp servers on them

Think it can ;)

I used my modem/router's firewall to block a DHCP server from another NAS/Firewall appliance I was building - I got it to work :D

How is your network setup? You could block one DHCP server if you have a firewall or router but since both DHCP servers are in the same segment, the fastest one will get your client an address... Otherwise it may be possible to use MAC address filtering on the 12.04 server by setting an explicit allow list.
