Introduction to TFTP Server and its Uses
TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that allows you to transfer files between a client and a server. It is commonly used for network booting, firmware updates, and transferring configuration files to network devices. In this article, we will guide you through the process of installing and configuring a TFTP server on Ubuntu 20.04.
Before we dive into the installation process, let’s take a moment to understand the uses of a TFTP server. One of the primary uses of a TFTP server is network booting. When a computer is configured to boot from the network, it needs to download the operating system image from a TFTP server. This is particularly useful in large-scale deployments where it is impractical to install the operating system on each individual machine manually.
Another common use of a TFTP server is for firmware updates. Many network devices, such as routers and switches, have the capability to update their firmware. These updates are often distributed as firmware image files that can be downloaded from a TFTP server. By configuring the device to retrieve the firmware image from a TFTP server, you can easily update the device’s firmware.
Additionally, a TFTP server can be used to transfer configuration files to network devices. Network devices often require specific configuration files to operate correctly. By hosting these configuration files on a TFTP server, you can easily distribute and update them across multiple devices.
