[K12OSN] FW: DHCP Option128/129 MOPTS - not working

[Peter Van den Wildenbergh]

Hi All :
 
We are struggling with option 128 / 129 on a Novell Netware 6 DHCP server.
What I would like to do is using TCP for NFS and not UDP.
 
I've read this:
http://wiki.ltsp.org/twiki/bin/view/Ltsp/KernelOptions#Etherboot
 
>From what I can see the root filesystem get mounted by the cmd:
mount -n -o ${MOPTS} ${NFS_IP}:${NFS_DIR} /mnt
in linuxrc.
 
We've put the following in 128/129
128    e4:45:74:68:00:00
129    MOPTS=nolock,ro,proto=tcp
 
(Found this on this list Dec 1 2004 - solved pivot_root hang)
 
According to ethereal we are still using UDP :-(
 
The reason for all this is to get (in case you want to know)
a server running K12LTSP with NX on one end and
clients on the other end of a 1MB pipe.
All works fine in a test lab were server and client are close to each other
as soon as we put the client a couple hops further away
the client boot process hangs on the pivot_root.
 
Any suggestions?
 
Peter
 
PS Is there a very detailed howto available on how to alter linuxrc?
so I can hardcode the proto=tcp... or at least get a couple extra 
echo statements in the script...
