Ah, I thought it was an internal openMPI error number and 'grep'ed the
source code without success. So "No rout to host" means that the TCP
package could not be sent (usually host down, broken routing table,
network interface down, ...). But it's 'ping'able and even rsh works

BTW, /etc/hosts.allow says "ALL : ALL", so there should be no trouble.
Do I have to modify /etc/securetty in order to allow orterun to access
the machines or is the rsh/rlogin entry sufficient?
