Background

As a few people have had issues with iPXE booting correctly a, seemingly decent work around seems to work for most people.

Configure system

Obtain root access through terminal to your FOG Server. There are multiple means to do so.

The most common methods are:

  1. Open a terminal or console window.
  2. Login as your self and sudo up to root, su to root, or login straight as root.

If you logged in as your regular user try the command: 

sudo su -

Enter your local user password.

If you don't have sudo permissions but know the root password, try: 

su -

Enter the root users password.

Of course logging in straight as root you don't have to do any more work.

Make things work

  • If you are trying undionly.kpxe and this is already configured as your boot file (option 67):
cd /tftpboot
mv undionly.kpxe undionly.kpxeREAL
ln -s pxelinux.0.old undionly.kpxe
  • If you want to keep troubleshooting for "other" users a little easier, change the boot file pointer back to pxelinux.0 (option 67)
cd /tftpboot
mv undionly.kpxe undionly.kpxeSOMERANDOMNAME
ln -s pxelinux.0.old pxelinux.0
  • Create the pxelinux.cfg folder as it was removed.
mkdir /tftpboot/pxelinux.cfg
  • Create the /tftpboot/pxelinux.cfg/default using whatever editor you desire.
vi /tftpboot/pxelinux.cfg/default
  • Code is below, change x.x.x.x to the FOG IP Address.
