# You should see a number of packages installed including <b>openssh-clients</b> and <b>openssh-server</b>
# <b><code><span style="color:#3366CC;font-size:1.2em;">openssh-server</span></code></b> installs a service called '''sshd'''. Confirm that this service is running by issuing the command:<br /><b><code><span style="color:#3366CC;font-size:1.2em;">service sshd status</span></code></b>
# Also, check you should confirm that the sshd service is configured enabled (to start automaticallyupon boot-up). To do this issuing the following command: <br><b><code><span style="color:#3366CC;font-size:1.2em;">chkconfig systemctl list-unit-list files | grep sshd</span></code></b>
# Now that you know the service is running investigate what port number and protocol sshd uses by issuing the command:<br /><b><code><span style="color:#3366CC;font-size:1.2em;">netstat -atunp</span></code></b>
# What protocol and port is the sshd process using? What is the state of the port? Why wouuld you think that UDP ports don't have a state?
