Question

I need to call a fabric method on a remote machine through django. I mean when user send a given request get the hostname of a remote machine.
Something like this:

def get_hostname(request):  
  hostname = os.system('fab remote_server hostname')  
  return hostname

For greater control and flexibility you should use fabric as a library. see: http://docs.fabfile.org/en/1.3.3/usage/library.html

import fabric.api as fab
from fabric.network import disconnect_all
from contextlib import contextmanager

@context_manager
def ssh(settings):
    with settings:
         try:
            yield
         finally:
            disconnect_all()

def hostname(request, host='somehost', user='someuser', pw='secret'):  
    with ssh(fab.settings(host_string=host, user=user, password=pw)):
         return fab.run('hostname')
