TFTP is the short form of ‘Trivial File Transfer Protocol’ that works as a medium for file transfer without user authentication. It is beneficial for efficient file transfers, network booting, firmware updates, backups, etc. TFTP is the simple version of FTP and works on the UDP or User Datagram Protocol. However, the TFTP server requires correct configuration involving setting up the storage directory and providing access permissions. That’s why many Rocky Linux beginners always need clarification while setting up a TFTP server and get errors. So this article has the complete method to configure and run a TFTP server on Rocky Linux 9.
How to Configure and Run TFTP Server on Rocky Linux 9
First, please update the current system as per the latest updates available in Rocky Linux 9 and then install the TFTP server utility:
sudo dnf install tftp-server
After installing the TFTP server, you must copy the tftp.service to tftp-server.service and tftp.socket to tftp-server.socket. First, copy tftp.service and tftp-server.service using the cp command:
Now, copy the tftp.socket to the tftp-server.socket:
Once you copy the services to the TFTP server, you need to edit the TFTP-server.service in the text editor:
In the above text, please replace the tftp.socket with the tftp-server.socket and replace the ExecStart as we did below:
In the above line, the -c option lets the TFTP server create the file, which means the client can upload files to your TFTP server. On the other hand, the -p option lets the TFTP server create the files with the current permission the source file includes.
Once done, please save the file to make the modification successful. After that, you can reload the daemon and enable the TFTP server:
sudo systemctl enable --now tftp-server
Moreover, you can also check the status of the currently running TFTP-server:
Now, you can run the following command to enable the read and write permission for TFTP server to upload folders:
