How to start a tftp server in ubuntu using systemctl start tftp command?

Question

I am using ubuntu 16.04 I have installed tftpd-hpa server. I want to start my server with systemctl start tftp command. I have created a tftp service file in system folder and the configuration is as follows

[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

Whenever I am running the

systemctl start tftp

I am getting the following message :

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

After executing:

systemctl status tftp.service 

I am getting the following message :

● 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
  Process: 3309 ExecStart=/usr/sbin/in.tftpd /var/tftp (code=exited, status=1/FAILURE)

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

Any guidance is greatly appreciated.

after running

journalctl -xe

It gave following message

Solution

Please modify you service file from:

[Unit]
Description=Tftp Server

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

StandardInput=socket

[Install]
WantedBy=multi-user.target

To this since it's a daemon:

[Unit]
Description=Tftp Server

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

[Install]
WantedBy=multi-user.target

Thanks @George. But it's not working. I edited my tftp.services file in the question and now I am getting less errors. So please check it and if possible tell me where I am wrong.

[George Udosen]

Please run journalctl -xe and lets see the output, add to your code don't remove any old entries jut add under as an update

[ams]

I ran the journalctl -xe command please check the output in question description. Thank You.

[George Udosen]

Please run which xinetd and tell me what comes out

[ams]

Output: /usr/sbin/xinetd

[George Udosen]

ok that's the problem, it should be run like /user/sbin/xinetd not /usr/sbin/in.tftpd

[George Udosen]

Oh great it worked if my updated answer helped please accept it.

Hi, I am facing a problem when I am starting a tftp server. Here, I am using inetd not xinetd . Error is : Failed to start etc-init.d-tftpd.mount: Unit etc-init.d-tftpd.mount failed to load: No such file or directory. Can you please help me out I tried various ways to solve but I am not able to solve this problem. Thank You ..!
