1. Install the package.
$ sudo apt-get install tftpd-hpa
2. Edit config file as follows.
$ sudo vi /etc/default/tftpd-hpa
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="-s -c -l"
Note: -l for listening all time this avoided the timeout issue, -c to create files in tftfp folder.
3. Create TFTP folder.
sudo mkdir /tftpboot
$ sudo chmod -R 777 /tftpboot
$ sudo chown -R nobody /tftpboot
4. Finally restart the app to apply new configuration.
sudo service tftpd-hpa restart
