Other Troubleshooting
0.32 and below
- From your FOG server test out tftp
tftp -v X.X.X.X -c get pxelinux.0
- From a Windows PC run at the cmd prompt: (Windows TFTP Service must be Installed first)
tftp x.x.x.x get pxelinux.0
0.33 and 1.x.x
- From your FOG server test out tftp
tftp -v X.X.X.X -c get undionly.kpxe
- From a Windows PC run at the cmd prompt: (Windows TFTP Service must be Installed first)
tftp x.x.x.x get undionly.kpxe
Expected Results
- If tftp & xinetd are running your should get:
Received XXXX bytes in X.X seconds....
Restart TFTP Service
- Restart the TFTP service.
service tftpd-hpa restart
Rights to tftpboot folder
- Are the rights to your tftpboot folder correct?
- If you tried the above Section-1.5.2 and you get the "Expected results" then the rights are correct.
Check DHCP Option 67
- Go to your DHCP and confirm that option 67 is set to undionly.kpxe.
- ==DHCP Settings==

FOG dnsmasq (ProxyDHCP)
- You would use ProxyDHCP if you do not have access to your DHCP server, or are using a device that isn't capable of specifying option 066 and 067 (next server and file name). The most popular ProxyDHCP method with fog is dnsmasq. This article will walk you through that:

MAC Server DHCP
Use OS X Server app to install and utilize DHCP.
Use DHCP Option Code Utility to generate the code necessary.
https://docs.google.com/uc?id=0BwD4il5Z1G6fTmFFYU91bDNuRmc&export=download
One MUST generate the codes in order for PXE booting to work!
bootpd.plist is located in /etc/bootpd.plist
- Option 66
- Option 67
- Sample bootpd.plist
- This is a sample file DO NOT USE THIS IN YOUR ENVIRONMENT!!!! OS X Server app will generate most of this code for you, this example file is to show you the place where the generated code needs to be placed.
- For Reference, your generated code should be placed between "dhcp_domain_search" and "dhcp_router"
- This is a sample file DO NOT USE THIS IN YOUR ENVIRONMENT!!!! OS X Server app will generate most of this code for you, this example file is to show you the place where the generated code needs to be placed.
