Hallo,
I had an openSUSE 10.3 home server. I used this server as a netboot server and I managed to upgrade 2 diskless PCs. After the server’s upgrade to 11.2, I cannot PXEboot any PC! So, I need to test the PXE boot options etc (since everything seems OK from the PCs side). Are there any tools that I can use?
Thanks
A direct upgrade from 10.3 to 11.2 is not recommended. You may have to readjust so many of your configuration setup.
Well, the upgrade was performed and it was OK. Since I have no X server on the server, it was a little bit painful for the PHP but, other than that everything seems to be better.
Anyway, the problem (after the useful help of VirtualBox, seems to be my
“default” file.
Specifically, I followed the openSUSE way of PXE boot ().
However, the PXE boot fails with the the error “Unknown keyword in configuration file”
The default file is:
default harddisk
#DISPLAY f1.txt
#F1 f1.txt
# hard disk
label harddisk
localboot 0x80
# install
label linux
kernel linux
append initrd=initrd splash=silent showopts

I see it refers to 11.1, is that OK? Are kernel image and initrd still there?
Yes.
initrd is copied from the ISO (mounted with -o loop on the server), as well as the kernel.
Let me explain:
I followed the SuSE install with PXE boot - openSUSE guide, with minor exceptions.
So my setup is the following:
TFTP server has 11.1 and 11.2 images.
The initrd and the kernels are copied from the respective ISOs.
The files:
were copied from the 11.2 i386 ISO.
The setup is the same as ir was before the upgrade. So, I cannot understand why the the NIC that used that environment to boot, now, they cannot. That’s why I setup a new VM in the VirtualBox to test it. There I see the error…
In the VirtualBox Machine, I can boot when I enter an option (eg 64b111).
But, from the rest of the PCs (including the VB Host!), I cannot.
Did you have a look in the messages? Beside that I prefer the atftp instead of the tftp package. If you used the yast control center to configure your tftp environment, I’m quite sure that it still uses tftp.
Well, as everybody suggests, I used the atftpd, since it should be better. Everything was configured with nano/vi, so, no yast. The “message” is a binary file. What puzzles me, are the following facts:
VirtualBox is receiving the DHCP and the boot data (since I can boot it when I enter the linux or the 64b111 command at the boot prompt)
All PCs (laptops and desktops) that before the server’s upgrade booted with the PXE, now they don’t!
I have no indication in the log files that the machines are requesting DHCP and boot data!
Again, let’s solve the only error that I have in my hand and I can work on. The “unknown keyword in configuration file” problem.
As PXE is nothing more than a DHCP and ATFTP teaming game: How does the dhcp server config looks like? As far as I know you should also see at least the pxelinux.0 being transfered to the client an the atftp server. Can you also specify more exactly at what point the error occurs? What steps get done (eg. DHCP IP address received?)?
Correct. As I dig further down the problem, it seems that either the PCs are not requesting DHCP information, or the DHCP so a reason is not responding. Anyway, the error occures when the pxelinux.0 file is tranfered. Because, I see it when the “default” file is read from the PXE client.
The DHCP requests are:

}
From the log files is pretty clear (to me because I know the MAC addresses) the the DHCP request arrived from the VirtualBox only. Anyway, I need to solve 2 issues. The 1st is the error message. What is wrong in the “default” file?
