The default location for the configuration file is /etc/ssh2/. You can edit the configuration file sshd2_config with your favorite text editor.
The configuration file consists of keyword-value pairs, one per line. Lines starting with the hash character # as well as empty lines are ignored. The configuration file is read when the server is started and each time a new connection to the server is made. If the configuration file is faulty or cannot be found, the server will not start.
For detailed information about the options available in the configuration file, see the sshd2_config man page.
