![]() Perhaps the most common use of the ping utility is in troubleshooting. Until stopped – keeps running the ping until stopped by the user (-t in Windows) Ping command syntax for Windows (ping -4/ping -6 in Windows, ping or ping6 in Linux) IP4 or IP6– responds with IPv4 or IPv6 addresses. The default value on Windows is 32 bytes, many Unix/Linux systems default to 64 bytes. Size– changes the size of the ping packet. On Windows systems, the default value is 4,000 milliseconds, or 4 seconds. Timeout– changes the timeout before the utility waits for a reply from the destination. Setting a higher number allows the ping to continue to run either as a way of gathering more data, for example, to see if the reply time varies, or as a way of ensuring that a system continues to be responsive. By default, this number is four on most Windows systems, and five on most Unix systems. Number (or count) – sets the number of echo requests, or pings, to be sent. Generally, using ping -? will result in a list of switches along with the corresponding letter to use the switch on the operating system. Here are some examples of ping command switches. For example, Windows uses a -n (number) to set how many pings to send, while most Unix systems use a -c (count). ![]() Unfortunately, there is no consistency across platforms for the different switches. There are numerous switches available for the ping command that allow the default settings to be customized for more specific purposes. However, the ping utility also provides several customizable options. Minimum = 4ms, Maximum = 4ms, Average = 4ms Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Īpproximate round trip times in milli-seconds: The following is the output of a simple ping to the target host : The remote host can be specified either by name or address. In its simplest form, the ping utility can be run with nothing more than the ping command and a destination. While echo request and echo reply are ICMP messages, the exact implementation of the Ping utility varies slightly among manufacturers. The ping utility has been incorporated into virtually every operating system with network support.
