# On your fedora host try the command <code>netstat -atn</code>. How is this output different?
# Without the <code>-n</code> option <code>netstat</code> attempts to resolve IP addresses to host names (using /etc/hosts) and port numbers to service names (using /etc/services)
# Examine the <code>/etc/services</code> file and find which ports are used for the services : <code>ssh, ftp, http</code>
# Now execute the command <code>netstat -au</code> What is the difference between <code>-at</code> and <code>-au</code>?
# When examining UDP ports why is there no state?
