In the second test, my computer remembered Google’s IP address, but could not actually reach the Google servers ( Request timeout). In the first test, ping told me that my machine could not even find the Internet address (IP 216.58.196.46) for. Or, for example #2, depending on exactly how the connection is failing: PING (216.58.196.46): 56 data bytesĪnd sometimes, if I have a particularly flaky connection, I’ll see a mixture of these messages. The first thing I notice is that it takes a lot longer for the command to respond: MacBook-Pro:~ ajm$ ping So what would happen if I could not connect to ? For example #1, I simulate a broken network connection to my Mac by unplugging my router from the wall, and re-run the command. When something is wrong (three examples): You can see from these examples that the connection is pretty good with average response times under 10ms. Minimum = 6ms, Maximum = 15ms, Average = 8ms Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Īpproximate round trip times in milli-seconds:

This is what my ping response looks like on a Windows computer when everything is working well: C:\Users\BJM>ping
#CHECK PACKETS FOR MAC INTERNET MAC OS X#
This is what my ping response looks like on my Mac OS X computer when everything is working normally here in Malaysia: MacBook-Pro:~ ajm$ ping At much above 200ms you’ll probably notice that you have a sluggish connection. A response time of 10ms or less is pretty fast, however values are often in the 100ms range. The response time is shown in “ms”, or millisecond, which is 1/1000th of a second. In its simplest form, the ping command provides two valuable pieces of information, whether the message was echoed back ( 64 bytes from…) and how long it takes to receive the message back (e.g., time=6.396 ms).ĭepending on what type of computer you are using, you may even get a summary containing minimum, maximum, average, and more.

In fact, ping uses the ” Internet Control Message Protocol Echo Request” as part of its underlying software design. If an echo of the ping comes back, it means that there is something out there. The original author, Mike Muuss, actually named the program after the “ping” sound that a submarine sends to detect objects in the water. The ping command is a simple way to verify that another computer can receive information from you.

Read below for details on how to launch a command line window and run ping from your Mac OS X or Windows machine. This can help you solve the problem and/or gain valuable debug information as a first step before calling support. You can use the ping command built into your Mac OS X, Windows, or Linux computer to identify basic network connectivity issues.
And please remember that your Support personnel are debug specialists, so follow their instructions when they step you through the troubleshooting sequence. Okay, this might not be enough to “wow” your fellow team members, however they will appreciate that you started the debug process. Next time you call your help desk, do you want to wow them with your networking knowledge? Using a command called “ping”, built right into your existing Mac, Windows, or Linux computer, will help identify basic connection problems.
