In this example, the Cisco IOS image is named. The file is located in the tftpboot directory. This download directory option is a configurable option, and you can select any valid directory on the host TFTP server. On the host TFTP server (in this case, a Windows 2000 PC), the Cisco IOS images reside in the tftpboot directory at c: ftpboot. The TFTP directory in Figure 2-1 is defined as c: ftpboot.

Security is reliant on the application and not the operating system.

For example, to copy a configuration file from a Cisco router to a UNIX or Windows host, the file must be predefined on the TFTP server with the appropriate access rights defined. This allows the remote hosts to TFTP the file from the remote TFTP client.

TFTP directory security (configurable on UNIX and Windows platforms) on the TFTP server is accomplished by allowing a predefined file on the server access to the file to be copied across. TFTP communication or data transfer is actually transferred between two UDP port values, a source and destination UDP port number.Ģ.

TFTP has no method to authenticate a username or password the TFTP packet has no field enabling the exchange of a username or password between two TCP/IP hosts. The following numbered list outlines the main components of TFTP:ġ. In fact, the only way to provide security to TFTP transfer is by defining (on the TFRTP server) the directory on the host TFTP device and the filenames that will be transferred. TFTP is typically used in environments where bandwidth is not a major concern and IP packets that are lost can be re-sent by the higher layers (typically the application layer). TFTP is a protocol that allows data files to be transferred from one device to another using the connectionless protocol, UDP.
