Utilisation

scrippy_remote

Ce module offre l'ensemble des objets, méthodes et fonctions permettant les opérations sur les hôtes distants accessibles via SSH/SFTP ou FTP:

• Exécution de commandes sur hôte distant
• Copie de répertoires/fichiers sur hôte distant
• Suppression de répertoires/fichiers sur hôte distant
• Copie de fichiers entre hôtes distants (la machine locale agissant comme tampon)
• ...

Attention: Il appartient au développeur du script de penser à fermer la connexion après usage.

Le module scrippy_remote.remote fournit plusieurs objets pour transférer des fichiers via SFTP, FTP(es) ou CIFS pour transférer des fichiers et SSH pour l'exécution distante de commandes.

Le code source du module scrippy_remote.remote et de ses sous-modules est également largement commenté et reste la meilleure source de documentation.

SSH/SFTP

Exécuter une commande sur un hôte distant:

import logging
from scrippy_remote import remote

remote_host = "srv.flying.circus"
remote_port = 22
remote_user = "luigi.vercotti"
key_filename = "/home/luigi.vercotti/.ssh/id_rsa"
password = "dead_parrot"

with remote.Ssh(username=remote_user,
                hostname=remote_host,
                port=remote_port,
                key_filename=key_filename,
                password=password) as host:
  stdout = host.exec_command("ls /home/luigi.vercotti", return_stdout=True)
  if stdout["exit_code"] == 0:
    for line in stdout["stdout"]:
      logging.info(line)

CIFS

Exemple d'utilisation :

with Cifs(
  hostname='SRV2GNC.gnc.recif.nc',
  shared_folder='BackupConfluence',
  username='svc.conf-bkp',
  password='MonSuperMotDePasse') as cifs:

  cifs.create_directory('myfolder')

  cifs.put_file(local_filepath='./mlocal-file.txt', remote_filepath='myfolder/remote-file.txt')

  cifs.get_file(remote_filepath='myfolder/remote-file.txt', local_filepath='./copy.txt')

  with cifs.open_for_write('myfolder/new-remote-file.txt') as file:
    file.write(b'Hello from cifs.open_for_write')

  with cifs.open_for_read('myfolder/new-remote-file.txt') as file:
    print(file.readlines())

  cifs.delete_directory_content('myfolder')
