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. This is the default.

Both secure and non-secure operation. This mode of operation, either
secure or non-secure, is determined by the client when it connects.
This operation is active when „Support Secure Connection‟ is enabled,
but „Required‟ is not.

Secure operation only. Secure operation uses encrypted connections
for the control connection. The data connections are encrypted or non-
encrypted based on the settings of the client. Secure operations also
require the server to have a signed server certificate it can use to prove
it is the actual machine the client wanted to reach and not an imposter.
This mode is active when both „Support Secure Connection‟ and
„Required‟ are enabled.
By default, the server requires a username/password combination to be
configured. The server supports one username/password combination to
authenticate remote users. There are three modes of authentication operation:

No support for anonymous login. This is the default.

Anonymous with no password. This is enabled when
„Allow
Anonymous Access‟ is checked, but „Require Username and
Password„ is not checked.

Anonymous with password requested (but not validated). This is
enabled when „Allow Anonymous Access‟ and „Require Username and
Password‟ are checked. This can prevent some types of attacks and is
required by some clients.
Note: To save the settings, run Backup (see page 2-10).
Once connected, a remote user is logged into the FTP root directory. This is
available from the QuickPanel View as \Temp\ftp and is a volatile RAM area.
Files placed in this area are not persisted over a power cycle/reboot and use
memory from the Storage Memory allocation. For this reason, remote users are
only able to read, rename and delete files from the FTP root directory.
Programs running on the QuickPanel can access the \Temp\ftp like any other
folder, but remote users cannot fill up storage memory.
