 In order to configure a TORQUE/PBS cluster accessed through ssh protocol, you should follow the next steps:
 
+1. Generate a public/private key pair without password :
+{{{
+#!sh
+[user@mycomputer~]$ ssh-keygen -t rsa -b 2048 -f $HOME/.ssh/meteo_rsa -N ""
+}}}
+
 1. Configure the `meteo` resource. If you do not have a [wiki:DRM4G#Resourcesection private_key] file, you can generate one by executing [http://www.openbsd.org/openssh/manual.html ssh-keygen]. This command will generate a public key (`~/.ssh/id_rsa.pub`) that will be necessary later on.

 That's it! Now, you can summit jobs to `meteo`.
