3.6 FTP Server
The File Transfer Protocol (FTP) server included with the QuickPanel
+
unit supports
standard (RFC 959). It does not support Secure File Transfer Protocol (SFTP) or implicit
FTPS, which uses different ports and is based on Secure Shell (SSH) rather than Secure
Sockets Layer (SSL).
The FTP server is configured with the Quick Panel + Setup Tool. By default, the server is
not enabled. Once enabled, a background program will run, waiting for clients to connect.
Up to ten connections are supported. Sessions that are idle for five minutes are terminated
by the server.
The server supports non-secure operation. All information including username, password,
and data is transmitted with no encryption and is susceptible to packet sniffing and
various FTP attacks.
Note If the server status is changed, the QuickPanel + must be restarted before changes
take effect.
3.6.1 Remote User Authentication
The FTP root directory is
available from the
QuickPanel
+
as \, and is the
root of the flash device.
The server only supports anonymous login with password requested (but not validated).
This may prevent some types of attacks and is required by some clients. Once connected,
the remote user is logged into the FTP root directory.
3.6.2 FTP with Removable Flash Devices
All removable flash devices remote-FTP users as directories off the FTP root directory.
Computer Flash card partitions display as directories such as
\SDMemory and USB Flash
Keys display as directories such as \Hard Disk . Full access privileges are granted for the
client in these folders/devices.
Removable flash device directories are captured when a session is opened and are not
changed while the session exists. If you start without an installed SD Card, close your
session and log on again to view the SD Card directory. If the SD Card existed when you
logged on, and is removed and inserted, it will still work, provided the SD Card’s device
name did not change during reinsertion.
