Ping is a special command on Linux, Mac and Windows computers that allows one computer to send a request to another computer on the Internet and measure the response time to see how long of a delay, or lag, exists between the two systems. It is installed by default on Ubuntu and is easy to use.
Open the terminal by clicking "Applications," "Accessories" and "Terminal."
Type the following:
Wait for a few results to print onto the screen and press "Ctrl-C" when you are finished. Ping will print out a report analyzing the response times and telling you the minimum, average, maximum and standard deviation in ping times. It will also tell you if any of the requests were "dropped," or unanswered.
Tips & Warnings
- Pinging a well known and reliable server such as Google that is known to respond to ping requests is a common way to quickly check connectivity to the Internet.
- Systems administrators seeking to secure their computers and cut down on wasted bandwidth will sometimes disable ping responses. As of April 2011, Google responds to ping requests, but they may not in the future.
