Comment démarrer un serveur TFTP dans Ubuntu en utilisant la commande systemctl start tftp?

J'utilise Ubuntu 16.04 J'ai installé le serveur tftpd-hpa. Je veux démarrer mon serveur avec la commande systemctl start tftp. J'ai créé un fichier de service TFTP dans le dossier système et la configuration est la suivante

[Unit]
Description=Tftp Server
After=network.target

[Service]
Type=forking
ExecStart=/usr/sbin/in.tftpd /var/tftp
ExecStop=/bin/kill -15 $MAINPID


[Install]
WantedBy=multi-user.target

Chaque fois que je lance le

systemctl start tftp

Je reçois le message suivant:

Job for tftp.service failed because a configured resource limit was exceeded. See "systemctl status tftp.service" and "journalctl -xe" for details.

Après avoir exécuté:

systemctl status tftp.service

Je reçois le message suivant:

● tftp.service - Tftp Server
   Loaded: loaded (/etc/systemd/system/tftp.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Wed 2017-07-26 14:38:22 IST; 26s ago

Jul 26 14:38:22 map-VB systemd[1]: tftp.service: Failed with result 'exit-code'.

Toute orientation est grandement appréciée.

après avoir couru

journalctl -xe

Il a donné le message suivant

Veuillez modifier votre fichier de service à partir de:

[Unit]
Description=Tftp Server

[Service]
ExecStart=/usr/sbin/in.tftpd
ExecStop=/bin/kill -15 $MAINPID

StandardInput=socket

[Install]
WantedBy=multi-user.target

Pour cela puisqu'il s'agit d'un démon:

[Unit]
Description=Tftp Server

[Service]
Type=forking
ExecStart=/user/sbin/xinetd
ExecStop=/bin/kill -15 $MAINPID
StandardInput=socket

[Install]
WantedBy=multi-user.target
