Dynamic "banners"

Some protocols feature so-called “banners”, which are short pieces of textual information that is sent to the client upon occurrence of certain events.

For example, the SSH2 protocol can send one such banner upon successful user authentication.

The FTP protocol has a richer set of banners: one that can be sent to the client upon connection (before authentication), one upon successful login, once upon failed login, and once when the user logs out.

All of these banners can be crafted by the Syncplify Server! Administrator to be dynamically built at run-time, using certain variables, at the exact time they are sent to each client. All of these variables must be enclosed between double curly braces.

For example, the following banner configured in the Admin UI:

{{software_name}} v{{software_ver}} FTP(E/S) Service Ready

will be sent to the client like this:

Syncplify Server! v6.0.8 FTP(E/S) Service Ready

So, what are the variable names that you can use? And what do they mean?
