FOG issues on Ubuntu 16.04 LTS
-
I am constantly setting up equipment for different courses, so therefore I constantly need to setup 20+ computers/laptops identically. I have been attempting to use FOG to do the imaging/multicasting but seem to be running into a number of issues.
First, I had set up the fog server and captured an image. I then tried to multicast that image to 2 computers as a test. The capture seemed to work, but after multicasting, I ran into an error when booting the clients. I kept getting an error that said “Invalid Partition Table!” While troubleshooting this, I attempted to reboot the server computer and my network changed my IP Address, causing the server to get all messed up.
Next, I decided to set up a new fog server using a static IP Address, when I did this, I ran into an issue with the DHCP. The clients were now unable to communicate with the server when PXE Booting so I was unable to connect the clients, capture images, and multicast.
Also, I seem to be having some strange networking issue in Ubuntu. When I connect the ethernet cable to the network port, it gives me the up and down arrows to show that it is connected. But when I then connect the ethernet cable to the switch to do the PXE Booting, the up and down arrows do not appear and the computer seems to constantly be searching for a connection.
I have been trying to troubleshoot this issue for a while now and haven’t had any luck on any of the forums that I have been on, someone please help!

@IT-Knight I am not sure where to start with this. The issue you described when plugging in the network cable is very hard to impossible for us to investigate as it’s something we can’t really replicate. Does the switch show a link (LED) when you plugin the cable? What kind of switch is this?
While Ubuntu 16.04.6 LTS is still supported I am wondering why you are still using this kind of dated version.

First let me say that you should/must set the fog server to a static IP address before installing FOG. FOG does not support dhcp supplied IP addresses. If the fog server changes IP addresses after FOG is installed you will have a very unhappy FOG server. There is a process to resync the fog configuration, but I would get your fog server configured for a static IP address before going through the process.
The clients were now unable to communicate with the server when PXE Booting so I was unable to connect the clients, capture images, and multicast.
The pxe boot settings in your DHCP server need to be updated to the actual (new/current) IP address of your fog server.
Also, I seem to be having some strange networking issue in Ubuntu. When I connect the ethernet cable to the network port, it gives me the up and down arrows to show that it is connected. But when I then connect the ethernet cable to the switch to do the PXE Booting, the up and down arrows do not appear and the computer seems to constantly be searching for a connection.
I would say lets get your IP address issue resolved with the fog server first. Then we’ll need you to clarify “when I then connect the ethernet cable to the switch to do the PXE Booting, the up and down arrows do not appear and the computer seems to constantly be searching for a connection.” Is the fog server doing this or the target computer?
