TFTP Issues

[Danny R]

Poor me not having any luck with FOG.

Today’s issue boot from network on any computer. Can’t find selected boot device press any key yada yada.

On a Win7 Machine I try to TFTP 10.16.10.126 get undionly.kpxe
Timeout occurred
Connect request failed

Even tried it from the same machine the file is on.

atg@atg-HP-Pro-3500-Series:~$ tftp -v 10.16.10.126 -c get undionly.kpxe
Connected to 10.16.10.126 (10.16.10.126), port 69
getting from 10.16.10.126:undionly.kpxe to undionly.kpxe [netascii]
Transfer timed out.

Turned off Ubuntu Firewall. Checked DHCP Server 2012 r2 for OPT 66 and OPT 67. Rebooted the Fog Machine. Rebooted my DHCP Service on my server. Disabled Windows Firewall on my server.

Checked my PCAP file with Wireshark didnt find anything.

Any ideas?

EDIT: Also says on machine No DHCP or proxy DHCP offers received.

Are you positive that your computers are not receiving anything from DHCP? Does wireshark show DHCP requests and responses?

@Wayne-Workman The computer gets an IP in PXE mode and eventually gets a TFTP timeout.

So it gets ip X.X.X.X then goes to TFTP . . . .

Time Out

@Danny-R What model of computer are you trying to network boot? Is UEFI enabled on it? Secure boot?

Optiplex 9020 tried also with an HP 3400 MT.

Same issue for some reason they both TFTP timeout.

@Danny-R Can you make sure tftp is running on your fog server? That link will tell you how to check it and start it.

You can also try to get the file via TFTP through the CLI on the FOG server itself. If it succeeds, it’s a firewall issue. If it does not, you have either permissions or TFTP goofed. The Troubleshoot TFTP article shows how everything should be and gives commands for all of it.
