   (description
    "The SSH2 protocol implemented in OpenSSH is standardised by the
IETF secsh working group and is specified in several RFCs and drafts.
It is composed of three layered components:

The transport layer provides algorithm negotiation and a key exchange.
The key exchange includes server authentication and results in a
cryptographically secured connection: it provides integrity, confidentiality
and optional compression.

The user authentication layer uses the established connection and relies on
the services provided by the transport layer.  It provides several mechanisms
for user authentication.  These include traditional password authentication
as well as public-key or host-based authentication mechanisms.

The connection layer multiplexes many different concurrent channels over the
authenticated connection and allows tunneling of login sessions and
TCP-forwarding.  It provides a flow control service for these channels.
Additionally, various channel-specific options can be negotiated.")

purpose is to put your real SSH server on another port and then let the script
kiddies get stuck in this tarpit instead of bothering a real server.

Since the tarpit is in the banner before any cryptographic exchange occurs, this
program doesn't depend on any cryptographic libraries.  It's a simple,
single-threaded, standalone C program.  It uses @code{poll()} to trap multiple
clients at a time.")
