[K12OSN] Resolution Config Problem

Wed Nov 18 15:10:51 UTC 2009

I just noticed you said your lts.conf is in:  

/var/opt/tftpboot/ltsp/i386/lts.conf

It should be in:

/var/lib/tftpboot/ltsp/i386/lts.conf (on Ubuntu anyway - not sure on
redhat systems)

It should be in whichever directory your pxelinux.0 is in.  As it
appears your lts.conf file is not being read, please look at the
k12linux docs for the version you are using to make sure you have it in
the right place.
