![]() ![]() ![]() Software Updates: TFTP servers are often employed to distribute firmware or operating system updates to network devices such as routers, switches, and so on.There are many freeware Trivial File Transfer Protocol (TFTP) servers on the Internet which are able to perform file transfers and help with other maintenance activities on Cisco devices, such as: For more information on this, refer to the Cisco TFTP Server. Note: The Microsoft Windows-based TFTP server previously provided by Cisco Systems has been discontinued and is no longer supported by Cisco Systems. The primary use of a TFTP server is to facilitate fast and efficient file transfers, typically in scenarios where simplicity and speed are more important than advanced security or authentication features. It serves as a communication platform for transferring files between client devices and the server. TFTP Server Software Selection and UseĪ TFTP (Trivial File Transfer Protocol) server is a simple file transfer protocol commonly used in networking. Conventionsįor more information on document conventions, refer to the Cisco Technical Tips Conventions. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. This document is not restricted to specific software and hardware versions. There are no specific requirements for this document. If the package is still not found, post the complete content of /etc/apt/sources.list and the output of sudo apt-get update.This document describes how to select and use a TFTP server. If you need to modify /etc/apt/sources.list, run sudo apt-get update afterwards, then try installing again. ![]() If you only find a line like deb precise main restrictedĪnd no line with universe, add universe at the end of that line, or a separate line with precise universe, as illustrated above. Or deb precise main restricted universe multiverse Check that this file contains a line like deb precise universe You can see what repositories you have enabled in the file /etc/apt/sources.list (and in files in the directory /etc/apt/).
