|     "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.")
