To upload a file to the tftp server use the put command as shown. To download a file from the tftp server use the get command as shown. If the tftp connection is successful, we’ll see a tftp prompt, where you can check the status of the connection. Then, use the tftp command to connect to the server. To test the TFTP server, you can install a commonly used TFTP client called tftp-hpa on your local computer. ![]() Create a TFTP Shared DirectoryĪfter making these changes, restart the TFTP server for the configuration to take effect. These commands set the ownership to the TFTP server’s default user and group ( nobody:nogroup) and allow full read and write access. Sudo chown -R nobody:nogroup /var/lib/tftpboot ![]() Once the configuration is complete, create a shared directory and set the required permissions that allow users to access it. Not specifying the -c flag disallows any connected client from uploading new items to the server. The -s ( -secure) flag is used here, and other possible flags include -c ( -create), -a ( -address), -u ( -user), etc. The TFTP_OPTIONS uses various aspects of the TFTP server’s behavior, including timeout, security settings, block size, transfer size limits, and other parameters related to file transfer operations. In this instance, we’ve set it to ‘ secure‘.

Open this file with your favorite text editor or use the following command. Once the installation is complete, you need to configure the TFTP server’s mail main configuration file located at /etc/default/tftpd-hpa. These access restrictions are specific to the server and should be configured based on individual requirements. Consequently, it is advisable for the remote server to implement access control measures or a firewall. It’s important to recognize that the TFTP protocol lacks authentication and security features. sudo systemctl status rviceĪlternatively, we can configure the TFTP server to start automatically during boot. After completing the installation, let’s confirm that the TFTP server is running and has been installed successfully. ![]()
