31.2.4 GUI-based FTP Clients
The following table describes some of the commands that you may see in GUI-based FTP clients.
Table 31-2 General Commands for GUI-based FTP Clients
COMMAND DESCRIPTION
Host Address Enter the address of the host server.
Login Type Anonymous.
This is when a user I.D. and password is automatically supplied to the
server for anonymous access. Anonymous logins will work only if your
ISP or service administrator has enabled this option.
Normal.
The server requires a unique User ID and Password to login.
Transfer Type Transfer files in either ASCII (plain text format) or in binary mode.
Configuration and firmware files should be transferred in binary mode.
Initial Remote Directory Specify the default remote directory (path).
Initial Local Directory Specify the default local directory (path).
31.2.5 TFTP and FTP over WAN Management Limitations
TFTP, FTP and Telnet over WAN will not work when:
1. You have disabled Telnet service in menu 24.11.
2. You have applied a filter in menu 3.1 (LAN) or in menu 11.5 (WAN) to block Telnet service.
3. The IP address in the Secured Client IP field in menu 24.11 does not match the client IP. If
it does not match, the HomeSafe will disconnect the Telnet session immediately.
4. You have an SMT console session running.
31.2.6 Backup Configuration Using TFTP
The HomeSafe supports the up/downloading of the firmware and the configuration file 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 backup the
configuration file, follow the procedure shown next.
Step 1. Use telnet from your computer to connect to the HomeSafe and log in. Because TFTP does not
have any security checks, the HomeSafe records the IP address of the telnet client and accepts
TFTP requests only from this address.
Step 2. Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
Step 3. Enter command “sys stdio 0” to disable the SMT timeout, so the TFTP transfer will not be
interrupted. Enter command “sys stdio 5” to restore the five-minute SMT timeout (default)
when the file transfer is complete.
Step 4. Launch the TFTP client on your computer and connect to the HomeSafe. Set the transfer mode
to binary before starting data transfer.
Step 5. Use the TFTP client (see the example below) to transfer files between the HomeSafe 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 and the SMT 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 HomeSafe
to the computer and “binary” to set binary transfer mode.
