According to the manual page, the Linux 89 ping 89 command uses the ICMP protocol s mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host of the gateway.

Path MTU discovery:
It is a simple protocol to find out the maximum MTU(Maximum Transmission Unit) a TCP path can take.
We use an option with -m do (prohibit fragmentation), want (do PMTU discovery, fragment locally when packet size is large), or dont (do not set DF flag).
Using of the Linux Command Ping (With Examples)
Other less commonly used switches for the ping command exist including [ -j host-list ], [ -k host-list ], and [ -c compartment ]. Execute ping /? from the Command Prompt for more information on these options.
Ping(8) - Linux man page
The ping command is a Command Prompt command used to test the ability of the source computer to reach a specified destination computer. The ping command is usually used as a simple way to verify that a computer can communicate over the network with another computer or network device.

It sounds simple, and it is. But you can use it to good effect. You can test whether your computer can reach another device like your router on your local network, or whether it can reach a device on the Internet. This can help you determine if a network problem is somewhere on your local network, or somewhere beyond. The time it takes packets to return to you can help you identify a slow connection, or if you 8767 re experiencing packet loss.
In this example, the ping command is used to ping the hostname . The -n option tells the ping command to send 5 ICMP Echo Requests instead of the default of 9, and the -l option sets the packet size for each request to 6555 bytes instead of the default of 87 bytes.
And of course, what we 8767 re talking about in this article is mostly about using ping to perform troubleshooting on a home or small business network. On larger networks, there 8767 s a lot more complexity to worry about. Plus, if you 8767 re tasked with troubleshooting larger networks, you probably already know how to use ping and many other networking tools.
For every ECHO_REQUEST sent a period '.' is printed, while for every ECHO_REPLY received a backspace is printed. This provides a rapid display of how many packets are being dropped. Only the super-user can use this option. This can be very hard on a network and should be used with caution.
Controlling the size of packets send:
Ealier a default sized packets were sent to a host but we can send light and heavy packet by using
We all have our favorite websites that we visit frequently if one of them doesn’t load, we really want to know why. Is it because we don’t have an Internet connection, or is it problems with our Internet service provider that are preventing us from accessing the website? Another reason could be the unavailability of the website itself. Whatever the reason, the Linux Ping command can give you all the answers.
For instance, you might not have an internet connection at all even though you are connected to your router. Sometimes the internet service provider has localized issues which prevents you from using the internet.
The 5% loss reported under Ping statistics for explains that each ICMP Echo Request message sent to was returned. This means that, as far as this network connection goes, it can communicate with Google s website just fine.
To test whether a website is available, type 89 ping 89 followed by the name of the site you wish to connect to. For example, to ping you would run the following command:
And it pretty much doesn 8767 t matter what operating system you 8767 re using. Pull up a terminal or Command Prompt window, and you can use ping on macOS, Linux, or any version of Windows.
