This is the fourth page of a five part tutorial on cloning worker nodes with Udpcast. The full tutorial includes

• Cloning Worker Nodes
• Udpcast Cloning: Preparing the Udp-sender
• Udpcast Cloning: Preparing the DHCP Server for PXE Booting
• Udpcast Cloning: Troubleshooting PXE Booting
• Udpcast Cloning: Imaging using Udpcast

Troubleshooting

If the file isn't in the proper place, the TFTP server won't be able to find it, and you'll receive an error from the nodes trying to boot up -

PXE-T01: File Not Found
PXE-E3B: TFTP Error - File Not Found
PXE-M0F: Exiting Intel Boot Agent

Then doublecheck that pxelinux.0 is in the location specified by the file /etc/default/tftpd-hpa.
