TFTP Timeout Issue/First FOG Install

[george1421]

@weltern Interesting what I expected to be wrong, is right. I need to think about this first. Because something is a bit off. You should not be getting this far because the ipxe boot file is coming form some place just not where I’m expecting it.

[george1421]

@george1421 OK so tell me a bit more about this network.

Is this a home network or a business?

Did you have fog setup here before?

For your dhcp server that your computers are using, what is supplying the dhcp information?

Home Network

Have not installed Fog here before, Although i have reinstalled Fog on the same Virtual machine (by removing the fogsettings files and running install again)

Built in DHCP server in Comcast Gateway. Comcast locks that bit down. Only thing i can do is set the scope size and manual reservations

[george1421]

@weltern When you installed fog either time, did you have it install the dhcp server?

1. I can’t understand how it get the next server (10.0.0.16) in the first try and iPXE loads correctly.
2. When iPXE asks for the next server it gets the comcast gateway.

I understand about the comcast gateway they will point to itself as the pxe boot server for some reason. So I can’t understand how you are getting the ipxe kernel from the fog server to begin with. It should be either left or right, not both ways.

It acts like there might be two dhcp servers on your home network.

Yes i did. Was following a video tutorial and wasn’t sure how i wanted to run fog on my network (either on bridged or on its own virtual network) and installed the DHCP service during the initial install.

Should i wipe the virtual machine and try again with installing fog fresh as i did this time and without the dhcp?

[george1421]

@weltern No we can just stop the service.

Issue the following command from the linux console command prompt.

sudo service isc-dhcp-server stop

Understand this will not fix our issue. It will break pxe booting but return you to a sane setup. From there we will install dnsmasq and get you moving in the right direction.

I will also give you a tip. Download and install putty on your windows laptop. Then you can connect to the fog server using putty (ssh). It makes copy and pasting a bit easier from the fog forums.

[george1421]

@george1421 When you get isc dhcp server stopped, then pxe boot your target computer. You should get something about the boot file was not sent or some kind of pxe timeout error. This is a good thing in a way. We can work from there.

[george1421]

@george1421 Here is the config file we will start with for dnsmasq. The contents of this below shall go in /etc/dnsmasq.d/ltsp.conf

# Don't function as a DNS server:
port=0

# Log lots of extra information about DHCP transactions.
log-dhcp

# Set the root directory for files available via FTP.
tftp-root=/tftpboot

# The boot filename, Server name, Server Ip Address
dhcp-boot=undionly.kpxe,,<fog_server_IP>

# Disable re-use of the DHCP servername and filename fields as extra
# option space. That's to avoid confusing some old or broken DHCP clients.
dhcp-no-override

# inspect the vendor class string and match the text to set the tag
dhcp-vendorclass=BIOS,PXEClient:Arch:00000
dhcp-vendorclass=UEFI32,PXEClient:Arch:00006

Tried it but nothing happened. Terminal never said anything stopped

When i ran the command and then checked the Status

When i tried to PXE boot after

[weltern]

@george1421 Don’t see this file in file veiwer. Is it hidden? what is the best way to copy this stuff over to it?

[george1421]

@weltern This last picture “When I tried to PXE boot after”. Is the exact error I want. That sounds a bit strange, but this is what I would expect to happen with only the dhcp server running on your comcast router.

The comcast router says I’m the next server, but it doesn’t provide the boot file.

Now you need to install dnsmasq on your fog server.

It will probably be a command like this:

sudo apt-get update

sudo apt-get install dnsmasq

Then paste the config file I posted below into /etc/dnsmasq.d/ltsp.conf

And finally start dnsmasq with this command sudo service dnsmasq start. All of these commands I posted here are from memory. They may not be exactly right but they are very close. Note: You may need to do a little research to find the exact command.

[weltern]

@george1421 Tried what you said but still got the same PXE error as last time now.

The file wasn’t there after it installed so i had to make it. Made it on the desktop and pasted your code into it and them sudo moved it to the location.
The file name is ITSP or LTSP? i have ITSP with the I capital.

[george1421]

@weltern With linux (unix) case is important.

I just sent you a IM. Look at the bubble on the fog forum tool bar.

[george1421]

@george1421 we moved the conversation to IM since turn around time was much quicker.

We got dnsmasq setup with all of the configuration required to pxe boot in a home router environment. DNSMasq probably won’t be needed in a business envionment since a business will typically have a dedicated dhcp server where you can set dhcp options 66 {next-server] and 67 {boot-file}. In the case of the home routers, dnsmasq will provide these missing values.

At this time the OP is able to pxe boot the VM target computer and was in the process of registering the VM with FOG.

Marking topic solved.
