I manage to get rshd/rsh and ssh to work. I can rsh / ssh to myself localhost. I notice that I cannot log in as root via rsh and have to use a normal user account for rsh. Is this normal? Does it matter to MPICH whether it's root or not root passwordless login?
When I ssh/rsh to another machine I have to use it's IP address. How do I get around this so that I can rsh/ssh using hostname?
I manage to get ssh passwordless to localhost, but not to other hosts. If I was using ssh, how would I configure MPICH-1 to use ssh instead of it using rsh by default?
Did anyone know how to make rsh passwordless?
