Re: k12ltsp as next-server - solved or almost

William,

thanks again for the reply.

I was able to log in yesterday morning by logging in to the own ip 
address, then copying the key from /root/.ssh/known_hosts to 
/opt/ltsp/i386/etc/ssh/ssh_known_hosts.

I think that's the same result as running ltsp-update-sshkeys.

Thanks to your help, starting next Tuesday, we will have people doing 
their desktop business with the help of K12Linux.
Maybe that's a first in Belgium ??!! :-)

greetings, J.
