FTP (File Transfer Protocol) est un protocole Internet utilis\u00e9 pour transf\u00e9rer des donn\u00e9es entre un serveur de fichiers et un client. Le FTP transf\u00e8re des fichiers en \u00e9tablissant une connexion entre l'ordinateur sur lequel l'utilisateur travaille et l'ordinateur qui h\u00e9berge le fichier. Les clients FTP fonctionnent sur des ordinateurs personnels connect\u00e9s au m\u00eame r\u00e9seau local et sont g\u00e9n\u00e9ralement lents et peu fiables.<\/p>\n\n\n\n

Un transfert de fichiers FTP se compose g\u00e9n\u00e9ralement de trois phases :<\/p>\n\n\n\n

    \n
  1. Connecter : Le Client FTP \u00e9tablit une connexion avec le serveur FTP afin de demander l'acc\u00e8s aux donn\u00e9es sur le serveur. La demande est un paquet unique (appel\u00e9 demande de connexion) envoy\u00e9 en texte clair (c'est-\u00e0-dire sans cryptage).<\/li>\n\n\n\n
  2. Connexion : d\u00e8s que l'acc\u00e8s est accord\u00e9, le client FTP se connecte et s'authentifie aupr\u00e8s du serveur. Pour cela, deux autres paquets doivent \u00eatre \u00e9chang\u00e9s.<\/li>\n\n\n\n
  3. Transfert : une fois que l'utilisateur s'est connect\u00e9, il peut commencer \u00e0 transf\u00e9rer des fichiers. Dans une transaction FTP typique, le client FTP initie une connexion en envoyant une requ\u00eate CONNECT au serveur FTP. La requ\u00eate CONNECT contient le nom de connexion et le mot de passe de l'utilisateur. Le serveur r\u00e9pond par un message de r\u00e9ponse 220 lorsque la connexion a \u00e9t\u00e9 \u00e9tablie avec succ\u00e8s.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"
