PXE Problems (random)

Use DNSMASQ to serve your bootfile and server information.

This should alleviate the TFTP errors you are experiencing.

Is there a specific reason you want to update the kernel? After you set up DNSMASQ if you have issues booting a device to the PXE menu, I would look into updating the kernel.

As for the kernel, have you thought about backing up your current kernel and manually downloading he new one?

Hello Jaymes,
Maybe there is a connection between the problems… So that was the idea to update the kernel.
But first i wanna check your solution out.

Thanks in advance…

Jaymes Driver

Definitely give the DNSMASQ a shot, I have to use this because my Novell network is sorely outdated and won’t support the length of the bootfile name either

Then if you still have issues come back and I would be happy to help you update your kernel.

Oh… Just for the information, the DHCP server is on another machine… is that a problem?

Does the DHCP server have the proper scope options specified (either Option 66 – IP of tftp server or next-server (and/or) Option 67/filename – undionly.kpxe)

Jvdkruit

i will check that out Tom… thanks

Jaymes Driver

With DNSMASQ you don’t need the DHCP on the server and you don’t need to adjust scopes. You supply all the information in the ltsp.conf file.

Jaymes… The PXE is also coming from another server… so… uhm… I feel myself a n00b right now…

Jaymes Driver

So your FOG server is not supplying your PXE or your boot menu?

Jaymes Driver

Could you give us a better understanding of your network and servers?

Jvdkruit

sure:
I have a DHCP Server: 192.168.50.1
And a PXE Server: 192.168.50.95
I’m now asking the network manager if i can get the pxe-settings, once i have that i will post it here!!

Hey John,

I am having the exact same issue when trying to upgrade my kernel to one of the latest versions. I also use our networks DHCP server that points to the FOG Server and Bootfile name undionly.kpxe. Though, I have no issues getting my machines to pxe boot into the FOG menus. Is there a known solution to this outside of using the FOG server for DHCP?
