41.5.5 TFTP File Upload
The ZyWALL also supports the uploading of firmware files using TFTP (Trivial File Transfer
Protocol) over LAN. Although TFTP should work over WAN as well, it is not recommended.
To use TFTP, your computer must have both Telnet and TFTP clients. To transfer the
firmware and the configuration file, follow the procedure shown next.
1 Use Telnet from your computer to connect to the ZyWALL and log in. Because TFTP
does not have any security checks, the ZyWALL records the IP address of the Telnet
client and accepts TFTP requests only from this address.
2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
3 Enter the command “sys stdio 0” to disable the console timeout, so the TFTP transfer
will not be interrupted. Enter “command sys stdio 5” to restore the five-minute console
timeout (default) when the file transfer is complete.
4 Launch the TFTP client on your computer and connect to the ZyWALL. Set the transfer
mode to binary before starting data transfer.
5 Use the TFTP client (see the example below) to transfer files between the ZyWALL and
the computer. The file name for the firmware is “ras”.
Note that the Telnet connection must be active and the ZyWALL in CI mode 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 ZyWALL to the computer, “put” the other way around, and “binary” to set binary transfer
mode.
