HP-UX Secure Shell Getting Started Guide HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3 (5900-3142, June 2013)

RhostsRSAAuthentication
Use this directive to specify whether to use host-based authentication with RSA host authentication.
NOTE: This directive is available for the SSH-1 protocol only.
The default setting is no.
For example:
RhostsRSAAuthentication no
RSAAuthentication
Use this directive to specify whether to use RSA authentication. RSA authentication is attempted
only if the identity file exists, or an authentication agent is running.
The default setting is yes.
For example:
RSAAuthentication yes
NOTE: This directive is available for the SSH-1 protocol only.
SendEnv
Use this directive to specify which variables from the local environ must be sent to the server.
Variables are specified by name and can contain the wildcard characters (*) and (?). Multiple
environment variables can be separated by spaces or spread across multiple SendEnv directives.
The default is not to send any environment variables.
For example:
SendEnv DISPLAY
Where:
DISPLAY is set as follows on the HP-UX Secure Shell client system:
$ export DISPLAY=john.users.com:0.0
NOTE: Environment passing is available for the SSH-2 protocol only. The server must also support
environment passing, and it must be configured to accept environment variables.
For more information on configuring the server, see “AcceptEnv” (page 63).
ServerAliveInterval
Use this directive to set a timeout interval value (in seconds) for a server. If no data has been
received from the server within the specified time, ssh sends a message through the encrypted
channel to request a response from the server.
NOTE: This directive is available for the SSH-2 protocol only.
The default setting is 0, indicating that no server alive messages are sent to the server.
For example:
ServerAliveInterval 0
ServerAliveCountMax
Use this directive to set the number of server alive messages that can be sent without ssh receiving
any messages back from the server.
Use this directive if the client or server depend on knowing when a connection is inactive.
If the number of server keep alive messages reaches the threshold, HP-UX Secure Shell disconnects
from the server, terminating the session.
