DHCP Service

[Nabeel]

I have installed FOG Project 1.5.6 on Ubuntu 18.04.2, during installation, I specified Yes to use the Fog server for DHCP Services, but I have already use DHCP server.
So now how to stop DHCP service on FOG server.

[Sebastian Roth]

@Nabeel To stop the service run: systemctl stop isc-dhcp-server
If you want to disable the service (not active after reboot) run: systemctl disable isc-dhcp-server

[Nabeel]

Thank you very much @Sebastian-Roth, it’s working.
Another problem has occurred that, after stopping dhcp service, my client system cannot connect with Fog server with network boot.
Please provide a solution i can connect fog server with network boot without using FOG/Ubuntu DHCP service, because I’m using Active directory 2012 with dhcp server on another machine.

Then you should search how to DHCP Proxy or your current DHCP Server on how to specifiy the boot file.

Search for the term “DHCP Proxy” if your current DHCP Server can’t specify a boot file.

@Nabeel Did you configure your dhcp server to supply dhcp options 66 and 67? For dhcp option 66 that needs to be the IP address of your fog server. For dhcp option 67 that should be undionly.kpxe for bios based computers and ipxe.efi for UEFI based systems.

If you need to support both systems in your environment then once you prove that the above options work you can review this article: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy
