# 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;">systemctl status sshd</span></code></b><br><br>'''NOTE:''' We can use the '''netstat''' utility as a trouble-shooting / confirmation tool to view the SSH service and determine which STATE the SSH service is performing:
:*'''LISTENING''' (waiting for a ssh connection attempt):*'''ESTABLISHED''' (connection established):*'''CLOSED''' (connection is closed):*'''WAITING''' (time between connection closed, and changing to LISTENING mode)<br><br>
# 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 | grep sshd</span></code></b>
# What protocol and port is the sshd process using? What is the state of the port? Why would you think that UDP ports don't have a state?
