Novice: rsh computer date -> Permission denied. rsh: connection failed

[clusardi2k@aol.com]

Hi,

  I have to be able to remotely execute a command from a SGI computer.
The man page tells me that I'm using the Kerberos version of rsh.

  On the remote (Red Hat Linux) host, I created a ~/.k5login file with
the line:

    clusardi at ONYX3900

  I have an account on both machines called clusardi.

On Onyx3900, this is what I do:

%rsh remote_computer date
Permission denied.
rsh: connection failed

Can you tell me specifcally what I need to do to get it to work?
