++Notes:
++
++MULTI-THREADED CIPHER:
++The AES cipher in CTR mode has been multithreaded (MTR-AES-CTR). This will allow ssh installations
++on hosts with multiple cores to use more than one processing core during encryption. 
++Tests have show significant throughput performance increases when using MTR-AES-CTR up 
++to and including a full gigabit per second on quad core systems. It should be possible to 
++achieve full line rate on dual core systems but OS and data management overhead makes this
++more difficult to achieve. The cipher stream from MTR-AES-CTR is entirely compatible with single 
++thread AES-CTR (ST-AES-CTR) implementations and should be 100% backward compatible. Optimal 
++performance requires the MTR-AES-CTR mode be enabled on both ends of the connection. 
++The MTR-AES-CTR replaces ST-AES-CTR and is used in exactly the same way with the same
++nomenclature. 
++Use examples: 	ssh -caes128-ctr you at host.com
++		scp -oCipher=aes256-ctr file you at host.com:~/file
++
++NONE CIPHER:
++To use the NONE option you must have the NoneEnabled switch set on the server and
++you *must* have *both* NoneEnabled and NoneSwitch set to yes on the client. The NONE
++feature works with ALL ssh subsystems (as far as we can tell) *AS LONG AS* a tty is not 
++spawned. If a user uses the -T switch to prevent a tty being created the NONE cipher will
++be disabled. 
++
++The performance increase will only be as good as the network and TCP stack tuning
++on the reciever side of the connection allows. As a rule of thumb a user will need 
++at least 10Mb/s connection with a 100ms RTT to see a doubling of performance. The
++HPN-SSH home page describes this in greater detail. 
++
++http://www.psc.edu/networking/projects/hpn-ssh
++
++BUFFER SIZES:
++
++If HPN is disabled the receive buffer size will be set to the 
++OpenSSH default of 64K.
++
++If an HPN system connects to a nonHPN system the receive buffer will
++be set to the HPNBufferSize value. The default is 2MB but user adjustable.
++
++If an HPN to HPN connection is established a number of different things might
++happen based on the user options and conditions. 
++
++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set 
++HPN Buffer Size = up to 64MB 
++This is the default state. The HPN buffer size will grow to a maximum of 64MB 
++as the TCP receive buffer grows. The maximum HPN Buffer size of 64MB is 
++geared towards 10GigE transcontinental connections. 
++
++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set
++HPN Buffer Size = TCP receive buffer value. 
++Users on non-autotuning systesm should disable TCPRcvBufPoll in the 
++ssh_cofig and sshd_config
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set
++HPN Buffer Size = minmum of TCP receive buffer and HPNBufferSize. 
++This would be the system defined TCP receive buffer (RWIN).
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf SET
++HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize. 
++Generally there is no need to set both.
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set
++HPN Buffer Size = grows to HPNBufferSize
++The buffer will grow up to the maximum size specified here. 
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf SET
++HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize. 
++Generally there is no need to set both of these, especially on autotuning 
++systems. However, if the users wishes to override the autotuning this would be 
++one way to do it.
++
++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf SET
++HPN Buffer Size = TCPRcvBuf. 
++This will override autotuning and set the TCP recieve buffer to the user defined 
++value.
++
++
++HPN Specific Configuration options
++
++TcpRcvBuf=[int]KB client
++      set the TCP socket receive buffer to n Kilobytes. It can be set up to the 
++maximum socket size allowed by the system. This is useful in situations where 
++the tcp receive window is set low but the maximum buffer size is set 
++higher (as is typical). This works on a per TCP connection basis. You can also 
++use this to artifically limit the transfer rate of the connection. In these 
++cases the throughput will be no more than n/RTT. The minimum buffer size is 1KB. 
++Default is the current system wide tcp receive buffer size.
++
++TcpRcvBufPoll=[yes/no] client/server
++      enable of disable the polling of the tcp receive buffer through the life 
++of the connection. You would want to make sure that this option is enabled 
++for systems making use of autotuning kernels (linux 2.4.24+, 2.6, MS Vista) 
++default is yes.
++
++NoneEnabled=[yes/no] client/server
++      enable or disable the use of the None cipher. Care must always be used 
++when enabling this as it will allow users to send data in the clear. However, 
++it is important to note that authentication information remains encrypted 
++even if this option is enabled. Set to no by default.
++
++NoneSwitch=[yes/no] client
++     Switch the encryption cipher being used to the None cipher after
++authentication takes place. NoneEnabled must be enabled on both the client
++and server side of the connection. When the connection switches to the NONE
++cipher a warning is sent to STDERR. The connection attempt will fail with an
++error if a client requests a NoneSwitch from the server that does not explicitly
++have NoneEnabled set to yes. Note: The NONE cipher cannot be used in
++interactive (shell) sessions and it will fail silently. Set to no by default.
++
++HPNDisabled=[yes/no] client/server
++     In some situations, such as transfers on a local area network, the impact 
++of the HPN code produces a net decrease in performance. In these cases it is 
++helpful to disable the HPN functionality. By default HPNDisabled is set to no. 
++
++HPNBufferSize=[int]KB client/server
++     This is the default buffer size the HPN functionality uses when interacting
++with nonHPN SSH installations. Conceptually this is similar to the TcpRcvBuf
++option as applied to the internal SSH flow control. This value can range from 
++1KB to 64MB (1-65536). Use of oversized or undersized buffers can cause performance
++problems depending on the length of the network path. The default size of this buffer
++is 2MB.
++
++
++Credits: This patch was conceived, designed, and led by Chris Rapier (rapier at psc.edu)
++         The majority of the actual coding for versions up to HPN12v1 was performed
++         by Michael Stevens (mstevens at andrew.cmu.edu). The MT-AES-CTR cipher was 
++	 implemented by Ben Bennet (ben at psc.edu) and improved by Mike Tasota 
++	 (tasota at gmail.com) an NSF REU grant recipient for 2013. 
++	 This work was financed, in part, by Cisco System, Inc., the National 
++         Library of Medicine, and the National Science Foundation.
