[K12OSN] Problems with dhcp packets

Tue Jul 3 05:10:42 UTC 2007

Just took a look at this and compared it to my dhcpd.conf.  I do see one
potential problem.  Take a look at the entry for host ws003, as an example:

host ws003 {
hardware ethernet 00:03:BA:D7:3A:C1;
fixed-address 192.168.2.117;
# kernels are specified
in /tftpboot/lts/boot/pxe/pxelinux.cfg/
filename "/lts/boot/pxe/pxelinux.0";

Note carefully the line that starts with "# kernels are specified" and
the one right after it, "in /tftpboot/lts/boot/pxe/pxelinux.cfg/". 
These two lines actually should be *one* line, like so:

# kernels are specified in /tftpboot/lts/boot/pxe/pxelinux.cfg/

What happens when you try to netboot a client that doesn't have a static
reservation?  Does it netboot, and do you get any error messages for it?
