View source for Setting up TFTP server on Linux machine

==Introduction==

This guide explains how to set up and configure a tftp server on a linux machine using the tftpd-hpa package.

==HOW TO==

===Set up===

Ensure tftpd-hpa has been installed on the machine. This can be checked by running 'sudo apt install tftpd-hpa'. Ensure the service is active and enabled with the command 'sudo systemctl status tftpd-hpa'. To start the service run the command 'sudo systemctl start tftpd-hpa', this is not required if the service is already running. To make the service run when the machine is booted enter the command 'sudo systemctl enable tftpd-hpa', this is not required if the service is already enabled.

===Configuration===

The configuration file for the tftp server is located in the file /etc/default/tftpd-hpa. This allows you to configure the tftp root directory, username, ip address and port and additional option. When using the PUT command from the client ensure that the option --create is configured. Ensure there is no firewall rules preventing traffic on udp port 69.

==Example==

/etc/default/tftpd-hpa

TFTP_USERNAME="tftp"</br>
TFTP_DIRECTORY="/srv/tftp/public"</br>
TFTP_ADDRESS="0.0.0.0:69"</br>
TFTP_OPTIONS="--create --secure"</br>
