#585 atftp: Failing pxe boot
If I start the installation process of a node and try to boot the node via pxe, the node does get the correct IP address via DHCP but the pxe boot process on the node exists with a file not found error message. Initially I thought it might be an update problem, so I additionally installed the xnba-undi and xnba-kvm package. This added the missing file to the /tftpboot directory, but did not change the error message.
Thank you very much for your help. The detailed description is added below.
Regards,
Andreas

On the management node I get the following error message:

If I look at mt /tftpboot directory I find everything which I think should be there, including the
/tftpboot/xcat/xnba.kpxe file. However I find one corrupt system link in the pxelinux.cfg directory:

Do you have gpxe installed gpxe-xcat-0.9.5-1.noarch and syslinux-xcat-3.82-1.noarch.rpm. if so run makedhcp -n and makedhcp -a service dhcpd restart and try again.
I found the problem. I tried to increase the log level of atftpd by modifying the /etc/init.d/tftpd file. To increase the verbosity I added -v 5 or -v 7 to the startup option of atftpd. The correct syntax however is --verbose=7 . The previous version adds the 5 or the 7 to the path for the boot image. That's where the strange path in the error log comes from.
With the correct option the pxe boot works perfectly.
Now I have a new problem with the repositories, but that has to wait until after my holidays ...
Thanks,
Andreas
