[SOLVED] Execute program

Hi everybody,

I have a problem using the execute program module, the command I am trying to execute is

ssh user@remotehost touch /home/user/test

The actors are: my laptop, server1, server2.

the hosts recognize themself without password but with pub/private keys.

when I launch it from rapidminer with my laptop (authenticated in the same way) everything goes fine, but when I try to run it from rapidanalytics (remotely) it gives me this error:
