[K12OSN] pxe booting

[Paul Karrel]

Hi 
I need help solving a pxe problem,
the pc starts the pxe; the dialog passes by, I can see the NIC has
obtained the an IP from the dhcp server ;on the pxe host monitor one
sees
ip=192.168.2.21:192.168.2.6:192.168.2.1:255.255.255.0; these are
correct 

1) next TFTP prefix lts/pxe {which exits as subdirectries under
tftpboot }
  now the problems start
the pxe program tries  to find pxelinux.cfg/default this folder & file 
exits /tftpboot/lts/pxe/pxelinux.cfg ;;  ls -Z
/tftpboot/lts/pxe/pxelinux.cfg/default shows -rw-rw-r-- root   root   
default
regardless on the pxe host monitor is the prompt boot:

if I typevmlinuz.ltsp root=/dev/ram0 rw initrd=initramfs.gz; the os
starts to load 
creating     new ramdisk to hold our root fs
mounting  root file system:/opt/ltsp/i386   {as specified in dhcp}
input :        ps/2 genric mouse as /class/input/input1
mount :   unknown host
mount: nfsmount failed: no such file or directory
mount: mounting /opt/ltsp/i386 on newroot/nfsroot failed:invalid
argument

now I can go to another pc & issue mount nfs pkcentos:/opt/ltsp/i386
/mnt with no problem {pkcentos is the hostname of the ltsp } and view
ths contents
I can use nslookup pkcentos and that resolves to 192.168.2.6. 

I have turned selinux & the firewall off. Any suggestions would be
welcome
