rsh without password

hi
I need to enable rsh on some machines. I put their hostnames into /etc/hosts.equiv so it looks like:
host_name +

But when I try

Code:

rsh hostname -n 'echo $SHELL'

I'm allways asked for passwd. What's wrong?

rsh is not very secure, i reccomend you use ssh instead.

I have to use rsh, I need it because of MPI....

There is a way to setup MPI to use ssh

I just like to tell everybody that at last I found out why my rsh was using
Kerbos5 resulting in annoying messages (when am trying to get a clean passwordless rsh). As I analysed from the list:

Connection refused
Trying krb4
Connection refused
Trying normal

The first being a kerberos 5, then a version 4 try before finally a normal
being successful. I thought there must be more than one version of rsh installed. So I typed 'locate rsh'. I try the first on the list. I typed '/usr/bin/rsh localhost' and that worked fine. Then typed 'which rsh'. To my surprise it says '/usr/kerberos/bin/rsh'. I then
looked at my $PATH and see that that's the first folder that's being pathed. So I removed it. Problem solved.
