When the ping test and the traceroute test both indicate everything is working, you are the proud owner of a working network interface. The next step you may need to take is to test the availability of services. You have two methods of testing service availability: those for services on your computer or those for services on external computers. Many tools are available to test service availability. I won't try to be exhaustive here, but I will discuss two of the most popular tools to check service availability. First, you can use the netstat tool, which can test the availability of services on the host where you run the command. Then, you will read about nmap, which you can use to test the availability of services on other hosts.
