Rethink that. OpenSSH using key-based authentication is the best way to
do what you wish.
However, I use which command to find out where rsh is, it shows
/usr/kerberos/bin/rsh
And in /etc/xinit.d directory I can't find the rsh, rlogin, and rexec
daemons.
Probably because they have been deprecated and thus omitted from your
distro, and for very good reasons.
So my problem is how to enable rsh to log in nodes without password.
Use ssh instead. Create RSA keys for yourself:
$ ssh-keygen -t rsa
Copy your ~/.ssh/id_rsa.pub to the
remote_systems:/home/amy/.ssh/authorized_keys.
