TFTP is available in Windows operating systems as standard. It enables the simple transfer of files to/from other devices over the network.
The syntax of the TFTP call is dependent on the operating system. The syntax under Windows:
- tftp -i <IP address Host> [get|put] source [destination]
Note: The ASCII format is pre-configured on many TFTP clients. Binary transmission therefore usually needs to be selected explicitly for the transfer of binary data (such as firmware). Parameter '-i' is used for this in this example under Windows.
If the device is password-protected, user name and password must be included in the TFTP command. The file name is either made up of the master password and the command to be executed (for supervisors), or of the combined user name and password separated by a colon (for local administrators), with the command as a suffix. A command sent by TFTP therefore resembles the following:
- <Master password><Command> or
- <User name>:<Password>@<Command>
The rights to use TFTP can be restricted for administrators—see also “Managing rights for different administrators”.
