Chapter 29 Tools

1Use telnet from your computer to connect to the ZyXEL Device and log in. Because TFTP does not have any security checks, the ZyXEL Device records the IP address of the telnet client and accepts TFTP requests only from this address.

2Enter command “sys stdio 0” to disable the management idle timeout, so the TFTP transfer will not be interrupted. Enter command “sys stdio 5” to restore the five- minute management idle timeout (default) when the file transfer is complete.

3Launch the TFTP client on your computer and connect to the ZyXEL Device. Set the transfer mode to binary before starting data transfer.

4Use the TFTP client (see the example below) to transfer files between the ZyXEL Device and the computer. The file name for the configuration file is rom-0 (rom-zero, not capital o).

Note that the telnet connection must be active before and during the TFTP transfer. For details on TFTP commands (see following example), please consult the documentation of your TFTP client program. For UNIX, use “get” to transfer from the ZyXEL Device to the computer and “binary” to set binary transfer mode.

29.7.5 TFTP Command Configuration Backup Example

The following is an example TFTP command:

tftp [-i] host get rom-0 config.rom

where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the ZyXEL Device IP address, “get” transfers the file source on the ZyXEL Device (rom-0, name of the configuration file on the ZyXEL Device) to the file destination on the computer and renames it config.rom.
