# This very simple experiment will ssh in a linux box, and from there
# issue a ping command towards a landmark (default faraday.inria.fr)
#
# $ ping.py -u root mybox.domain.com
#
# would do the equivalent of
# ssh root@mybox.domain.com ping -c3 faraday.inria.fr
#
# If nepi is not installed in your system, and you only have a git clone
# you might wish to do instead
#
# $ cd /src
# $ python ../examples/linux/ping.py -u root mybox.domain.com
# let's be ready for python3
