How you exec something in the master produce a file and
this files you transfer it to your node?

take a look at the template(), inline_template() and generate() function:

        exec { "sshkeygen":
                path    => "/usr/bin:/usr/sbin:/bin",
                creates => [ "puppet:///myuser/files/$username/id_rsa" , "puppet:///myuser/files/$username/id_rsa.pub" ],
                command => generate("/bin/bash","/etc/puppet/manifests/myusers/sshkeygen.bash" )
        }


this command does not work!! why?

err: Could not retrieve catalog from remote server: wrong header line format
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run

At least the following things are wrong/do not work as you seem to
expect it:

* The generate() function is run on the master while compiling the
catalog.
* The exec then tries to execute the stdout of the script on the
client.
* The "creates" parameter avoids running the command when the
specified files exist. This only checks local files and not
puppet:/// urls.

I use this inside the class

generate("/bin/bash","/etc/puppet/manifests/myusers/sshkeygen.bash")

and I am generating a key inside the server but the permission of the folder
must be: user: puppet group: puppet
