→Investigation 1: How do you enable the sshd service.
# You should see a number of packages installed including <code>openssh-clients</code> and <code>openssh-server</code>
# <code>openssh-server</code> installs a service called <code>sshd</code>, confirm this service is running by issuing the command:<br /><code>systemctl status sshd.service</code>
# Now check that the sshd service is configured to start for runlevels 2, 3, 4, & 5, by issuing the commandautomatically:<br /><code>systemctl is-a list-units | grep enabled sshd</code> # If the .service is not configured correctly fix it by issuing the command:<br /> <code>chkconfig --level 2345 sshd on</code>
# Now that you know the service is running investigate what port number and protocol sshd uses by issuing the command:<br /><code>netstat -atunp</code>
# What protocol and port is the sshd process using?
