3.6 FTP Server
The FTP server included with the QuickPanel
+
supports standard (RFC 959). It does not
support SFTP or implicit FTPS, which uses different ports and is based on SSH rather
than 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 susceptible to packet sniffing and various
FTP attacks.
Note
If the server status is changed, the QuickPanel
+
must be re-booted before changes
take effect.
3.6.1 Authentication of Remote Users
The FTP root directory is
available from the QuickPanel
+ as \ and is the root of the
flash device.
The server only supports anonymous login: Anonymous with password requested (but not
validated). This may prevent some types of attacks and is required by some clients. Once
connected, a remote user is logged into the FTP root directory.
3.6.2 FTP with Removable Flash Devices
All removable flash devices appear to remote FTP users as directories off the FTP root
directory. Computer Flash card partitions display as directories such as
\SDMemory and
USB Flash Keys 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 SD Card installed, you will have
to close your session and login again to see the SD Card directory. If the SD Card existed
when you logged in and is removed and inserted, it will still work, provided the SD
Card’s device name did not change during reinsertion.
