NOTE:
•

You can use the FTP service after you have configured authorization and authentication on the FTP
server. Multiple clients can simultaneously access the FTP server. A remote FTP client sends a request to
the FTP server. The FTP server executes an action accordingly and returns the execution result to the FTP

client.

•

After you have configured authentication and authorization on the FTP server, you need to set the user
level to 3. Otherwise, when you use the backup files to restore those on the SecBlade card, “You have no
rights to store files” will be prompted.

Enable the FTP client program on the PC.

In the following example, Windows XP’s built-in FTP client program is illustrated.
Enter ftp in the DOS window.

C:\Documents and Settings\Administrator>ftp

Upgrade applications.

Using FTP, you can upload application files from the client to overwrite the existing application files on

the server (SecBlade card) to implement application upgrade. The upgraded application files take effect

at the next boot.

NOTE:
•

When you upgrade an application file, if the file name already exists on the FTP server, the existing file
will directly be overwritten.

•

You can upgrade configuration files in the way you upgrade application files. You can use a text editor
to modify a configuration file. You can download the modified configuration file to the SecBlade card

and the modified configuration file takes effect at the next boot.

Back up application files.

Using FTP, you can download application files from the FTP server (SecBlade card) to the FTP client (the
PC) for the backup purpose.
