FTP Server
Path: Administration > Network > FTP Server
The FTP Server settings enable (by default) or disable access to the FTP server and
specify the TCP/IP port (21 by default) that the FTP server uses to communicate with
the Rack PDU. The FTP server uses both the specified port and the port one number
lower than the specified port.
You can change the Port setting to the number of any unused port from 5001 to 32768
for added security. Users must then use a colon (:) to specify the non-default port
number. For example, for port 5001 and IP address 152.214.12.114, the command
would be ftp 152.214.12.114:5001.
FTP transfers files without encryption. For higher security, disable the FTP
server, and transfer files with SCP. Selecting and configuring Secure Shell
(SSH) enables SCP automatically.
For detailed information on enhancing and managing the security of your
system, see
