Hi:

I`m working with LAM 7.1.1. My cluster have 4 nodes. I ran "recon" and "lamboot" without problems, but when I run "mpirun C hello", I obtain the following error message:

mpirun: cannot start hello on n1: Connection refused.

I use "rsh" to the communication with nodes.

I wait for help.

Best Regards 

Jose
