Authentication Preferences
The following four configuration options allocate preferences to the authentication methods 
that should be used. As above, a value of zero disables the particular authentication method 
and lower values indicated greater preference than higher values. So, for example if MAC 
SHA1-96 was the preferred method for authentication, this option would be given the value 1 
and the other options given a value of 2 or greater. If all these parameters are set to the same 
value, the router automatically uses them in the following order: SHA1, SHA1-96, MD5, 
MD5-96.
MAC MD5
The preference level for MAC MD5.
MAC MD5-96
The preference level for MAC MD5-96.
MAC SHA1
The preference level for MAC SHA1.
MAC SHA1-96
The preference level for MAC SHA1-96.
Enable Server Keepalives
When enabled, enables server keepalives to use the same tcp connection for HTTP 
conversation instead of opening new one with each new request.
Enable Debug 
The router supports logging and output of debugging information for situations where there 
are problems establishing a SSH connection. When enabled, this checkbox causes the router 
to trace and output information that should be helpful in diagnosing and resolving the 
problem.
