Hi Morgan,
You just need to use the execute() function, which allows you to run
any task/function on any host/list of hosts/etc. See:
http://docs.fabfile.org/en/1.4.2/usage/execution.html#intelligently-executing-tasks-with-execute
It will even look at the @hosts decorators if you are using them, so
all you should have to do is change is_it_blocked() to:
@task
def is_it_blocked():
"""Verifie si un mail est bloqué sur firewall ou la
passerelle SMTP"""
address = raw_input("Entrez l'adresse ou mot clé à
rechercher: ")
execute(ask_fw, address)
execute(ask_smtp, address)
HTH,
Jeff
