Cannot get iPXE to connect to FOG Server

[RAV]

@trev-lchs Ohh, okay, that makes sense. A windows server would have made this a lot easier I think, haha. I appreciate the help though

[Trev-lchs]

@rav I was assuming you were setting this up on a windows network, with an Microsoft windows domain. So is your DHCP server a linux box then?

[RAV]

@george1421 I run an Ubuntu server on VirtualBox and we use this as part of our imaging process in my job. It’s isolated on a computer that’s not regulated by my company, so it’s free to do whatever without blocks or firewalls.

I’m not sure how to change the dhcp options on my server.

[RAV]

@trev-lchs Yes, this is a linux/ubuntu server setup on VirtualBox

[RAV]

@george1421 " dhcp server, dhcp options 66 should be the ip address of your fog server, and dhcp option 67 should be undionly.kpxe for a bios based computer or ipxe.efi for a uefi based computer."

Can you tell me how to go about doing this?

[george1421]

@rav So just to be clear on this.

You are running fog on an isolated network. Is that correct?

When you installed FOG did you tell the installer to install the DHCP server?

[RAV]

@george1421 I believe I did make that choice, yes. I was following a guide. And it is on an isolated network.

[george1421]

@rav Ok lets assume yes.

The following command will tell if the dhcp server is running in memory.

ps -aux | grep isc This should return 2 lines. One of the lines will be the grep process and the second should be the process running the isc-dhcp server.

Another check we can do is see if the config file exists and is populated.

See if this file exists /etc/dhcp/dhcpd.conf

It should be populated with something that looks like this: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Example_1

[RAV]

@george1421 So, I actually had to manually create that /etc/dhcp/dhcpd.conf file. Which tells me the DHCP probably wasn’t set up correctly from the beginning, I’m guessing.

[george1421]

@rav Does your fog server have internet access? Possibly by a management interface? If yes then you can manually install the dhcp server. The config is as I pointed out before.

https://www.linuxfordevices.com/tutorials/ubuntu/dhcp-server-on-ubuntu

You will want to create your dhcp pool on the same subnet as imaging network interface.

[RAV]

@george1421 Okay, I went about creating the DHCP server. What should I do next?

[george1421]

@rav If you are using the config file from the web site, updated the scope in that config file to match the imaging subnet. Once that is set, I would restart the isc-dhcp server, then place an operating windows computer on that imaging subnet. Use ipconfig to confirm a windows computer can pull the IP address and ping the fog server. IF that all passes, then you should be able to pxe boot because the isc-dhcp config will / should point towards the fog server for pxe booting.

[RAV]

@george1421 Have I done this right? I’m still getting “No DHCP or proxyDHCP offers were received.”

[george1421]

@rav How about you share your dhcp config with my using a file share site so I can look at the entire config. Also provide the output of this command ip a s and the subnet you need for this dhcp server. I think that will be the shortest path to done.

[RAV]

@george1421 said in Cannot get iPXE to connect to FOG Server:

Also provide the output of this command ip a s and the subnet you need for this dhcp server.

I’m not sure how to do this. Do I put “ip a s” at the end of the code?

Sorry I should have been more clear. On the fog server linux console run that command. It will list out the network adapters configured in your computer.

[george1421]

@rav The config file you provided is for the dhcp client (app that runs on your computer that contacts the dhcp server). the file we are looking for is this: /etc/dhcp/dhcpd.conf
