There is no concept of user accounts so anyone will be able to connect to your TFTP server. Due to this limited functionality, TFTP servers can have an extremely small footprint on the disk as well as in memory, making it ideal for use in embedded network devices.Ĭaution: TFTP has zero security. The protocol is not capable of allowing more advanced functionality but compensates by using the lockstep method of fault-tolerance that makes it extremely reliable. In contrast, TFTP offers only the ability to upload or download a file and uses UDP over IP instead of the more standard TCP/IP stack. While logged in to an FTP server, users can usually list, delete, rename, upload, or download files and change directories.
