In TFTP, the user name and password are coded in the source (TFTP read request) or target file names (TFTP write request). The file name is either made up of the master password and the command to be executed, or of the combined user name and password separated by a colon, plus with the command as a suffix. A command sent by TFTP therefore resembles the following:
- <Master password><Command> or
- <User name>:<Password>@<Command>
Examples (the LANCOM has the address mylancom.intern, the master password is 'RootPwd' and a user has been set up named 'LocalAdmin' with the password 'Admin'):
- Read the configuration from the device (supervisor only) tftp mylancom.intern GET RootPwdreadconfig mylancom.lcf
- Write the configuration to the device (supervisor only) tftp mylancom.intern PUT mylancom.lcf RootPwdwriteconfig
- Read out the device MIB (for the local administrator) tftp mylancom.intern GET localadmin:Admin@readmib mylancom.mib
For the menus and available commands, the same limitations on rights apply as with Telnet.
