During configuration, the SSH2_CONFIG. file is copied to TCPIP$SSH_DEVICE:[TCPIP$SSH.SSH2].
When the user invokes the SSH command, the SSH client process reads the file
and creates the run-time version of the configuration parameters. If you want
to specify user-specific parameters, you can create a client configuration
file in the [username.SSH2] directory. You can copy this
file from a UNIX or an OpenVMS system and then edit it, or create a new file
from the template supplied by TCP/IP Services. The file can be in either Stream_LF
or variable-length format. For more information about the client configuration
file, see Appendix B.
