ProFTPD supports a number of configuration directives that specify a file whose contents should be displayed to connected clients at various times:

• DisplayConnect
  Displayed to clients as soon as they connect
• DisplayLogin
  Displayed to clients once they have logged in using the USER and PASS commands
• DisplayFirstChdir
  Displayed to a client the first time it changes into a directory
• DisplayGoAway
  Displayed to a client when it cannot connect because the maximum number of connections from its Class has been reached
• DisplayQuit
  Displayed to a client when the session ends via the QUIT command

Note the subtle difference between DisplayConnect and DisplayLogin. A DisplayConnect file will be displayed to all clients; this makes it suitable for server banners, messages of the day, etc. A DisplayLogin file will only be displayed once the client has logged in.

The configured file paths can be either relative or absolute (except in the case of DisplayConnect, which always requires absolute paths). In the case of a relative path, the file is assumed to be in the starting directory a user, i.e. the <Anonymous> directory for anonymous logins, and the user's home directory for non-anonymous logins. Note: If DefaultRoot is in effect, then the file must reside inside the chrooted directory. If the configured file cannot be found or accessed, no error occurs and nothing is logged or displayed to the client.

Display Variables
The following table contains the variables that can be used in Display files. Be aware that not all of these may have a rational value, depending on the context in which they are used (e.g., %u if IdentLookups are off).

Other contrib modules may provide additional variables for use as well; please consult their documentation for more information.
