To run an OpenSSH server, you must first make sure that you have
the proper RPM packages installed. The
openssh-server package is required and depends on
the openssh package. Both of these packages are
included in Red Hat Linux 7.2.
The OpenSSH daemon uses the configuration file
/etc/ssh/sshd_config. The default configuration
file installed with Red Hat Linux 7.2 should be sufficient for most
purposes. If you want to configure the daemon in ways not provided by
the default sshd_config, read the
sshd manual page for a list of the keywords that can
be defined in the configuration file.
To start the OpenSSH service, use the command /sbin/service
sshd start. To stop the OpenSSH server, use the command
/sbin/service sshd stop. If you want the daemon to
start automatically at boot time, see Chapter 8
for information on how to manage services.
