Copy and execute code for im probes in one 1.4 is located here:

http://dev.opennebula.org/projects/opennebula/repository/revisions/one-1.4/entry/src/im_mad/im_ssh/one_im_ssh.rb#L60

That ssh connection creates the remote directory and writes the script
using "cat >" (script is sent in stdin).

By default remote scripts directory is /tmp/one-im. Check that is dir
and files do have correct permissions if it exists, or delete it, will
be created when monitoring the host.

Bye
