Hi,
I am trying to set up a tftp server
I am accessing a tftp server from client.

- I am able to get a file from server.
- But I am not able to put a file on the server. Whenever I try to
do so, it is giving an error:

Error code 2: Access violation
-----------------------------------------------------------------
TFTP configuration in inetd.conf is as follows :

tftp dgram udp wait nobody /sbin/tftpd tftpd -s /var/tftp
------------------------------------------------------------------------------------
tftp file in init.d contains :

#!/bin/sh
#
# tftpd
#
case $1 in

start)
echo "tftpd starting"
/sbin/tftpd -s /var/tftp
;;

esac
--------------------------------------------------------------------------------------
TFTP. service file contains :

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

[Service]
Type=forking
ExecStart=/usr/sbin/inetd

[Install]
WantedBy=multi-user.target
----------------------------------------------------------------------------------------------
TFTP folder details :
owner: nobody
group: root
Permisiions: 777
--------------------------------------------------------------------------------------
What could be the reason for this error and how can I solve it?

Any help is highly appreciated.

Thank You

Try adding the -c option which allows the creation of files.

@michaelk

I tried adding but its not recognising.

I tried following and it shows error:

tftp dgram udp wait nobody /sbin/tftpd tftpd -s -c /var/tftp

tftp dgram udp wait nobody /sbin/tftpd tftpd -c /var/tftp

tftp dgram udp wait nobody /sbin/tftpd tftpd -c -s /var/tftp


Can you please tell me where to add the -c option.

What distribution are you running?

xinetd replaced inetd many years ago. On SysV init systems tftp ran from xinetd so script in init.d is not necessary.

On CentOS 7 guide has you installing and running xinetd although there is a separate tftp service. Still determining what is required.

I had to add the -c option to both xinetd and tftp.service and allow write permissions to the tftp directory. Not sure if the first -c is required. I had to restart several time before the service would show it using the -c option. You also have to change selinux to allow writing if enabled.

Hi @michaelk
I am using Ubuntu.
And I am using inetd.
There is no syslinux in my distro.

What version of Ubuntu are you running?

I would expect that if you used apt-get to install inetd that it would of actually installed xinetd.

How did you install tftp and inetd?

systemd not syslinux. I do not have a running Ubuntu system at the moment. systemd replaces xinetd as far as I know. There is no need for an init.d script.

I do not know how tftp is starting i.e xinetd/inetd, init.d script or systemd. What command did you run to start tftp server?

I suspect tftp is running from systemd. What is the output of the command?
systemctl status tftp

Hi,

I have used following command to start tftp :

systemctl start tftp

I am using inetd service. My requirement is to use inetd not xinetd.

Name of service file is tftp.service
The location of service file is in /etc/systemd/system

The output of systemctl status tftp is

��● tftp.service - Tftp Server
