 201     "The SSH2 protocol implemented in OpenSSH is standardised by the
 202 IETF secsh working group and is specified in several RFCs and drafts.
 203 It is composed of three layered components:
 204
 205 The transport layer provides algorithm negotiation and a key exchange.
 206 The key exchange includes server authentication and results in a
 207 cryptographically secured connection: it provides integrity, confidentiality
 208 and optional compression.
 209
 210 The user authentication layer uses the established connection and relies on
 211 the services provided by the transport layer.  It provides several mechanisms
 212 for user authentication.  These include traditional password authentication
 213 as well as public-key or host-based authentication mechanisms.
 214
 215 The connection layer multiplexes many different concurrent channels over the
 216 authenticated connection and allows tunneling of login sessions and
 217 TCP-forwarding.  It provides a flow control service for these channels.
 218 Additionally, various channel-specific options can be negotiated.")

 795 purpose is to put your real SSH server on another port and then let the script
 796 kiddies get stuck in this tarpit instead of bothering a real server.
 797
 798 Since the tarpit is in the banner before any cryptographic exchange occurs, this
 799 program doesn't depend on any cryptographic libraries.  It's a simple,
 800 single-threaded, standalone C program.  It uses @code{poll()} to trap multiple
 801 clients at a time.")
