I'm looking into possible causes of this failure.

1) /opt/ltsp/i386/etc/ssh/ssh_known_hosts
Does this contain the IP address of your LTSP5 server?

2) /opt/ltsp/i386/usr/sbin/ltsp-client-launch
# Find tftp server
# XXX: option routers is not guaranteed to be the tftp server.  Need to 
figure
#      out a better way to detect the tftp server address.
ROOTSERVER="$(cat /dev/.dhclient-eth0.leases |grep "routers" |awk 
{'print $3'} |sed 's/;//')"

This runs late during the client bootup right before X in order to 
figure out where to grab the lts.conf via tftp.  It seems that getting 
ROOTSERVER from option routers is definitely wrong here because there is 
no good reason that routers need be the same IP address as the LTSP 
server.  It also falls apart entirely if you have multiple LTSP servers.

I checked in a fix that improves this aspect.  It might not fix your 
bug, but it could use some testing anyway especially since you have 
multiple LTSP servers.

I built test RPMS into the test repository.

There could be something else wrong.  Let's see if the two ideas above 
help first.
