rsh on Cluster nodes
 

i have RedHat 7.3 in a 8 cluster Nodes
i have enabled rexec/rsh/rlogin in xinetd.d
we are using cluster for processors only so there is no user accounts on any clusters.
i can ssh to all the nodes
we want to run our programms to run on all the nodes using rsh.
but rsh is asking for the password.
any Experts.
