How to Use the Ping Command

Ping Demand in Linux
The ping command is one of the most utilized utilities for troubleshooting, tests, and identifying network connectivity issues.
Ping functions by delivering several ICMP (net controls Message process) Echo Request packages to a specific destination internet protocol address throughout the community and waits for an answer. Once the resort receives the plan, it will answer right back with an ICMP echo response.

With the ping order, it is possible to determine whether a remote location internet protocol address is energetic or sedentary. You can also find the delay that is round-trip chatting with the destination and look whether there is a packet control.
The ping energy was a right part associated with iputils (or iputils-ping) package, and that’s pre-installed on almost all Linux distributions. ping is also readily available on house windows, macOS, and FreeBSD.
Utilizing the Ping Command
The syntax for the ping order is as uses:
ping [OPTIONS] DESTINATION
To illustrate that is best how to ping a server order works let’s ping google.com:
ping google.com
The productivity shall take a look something like this:
PING.com this is certainly google (172.217.22.206) 56(84) bytes of data.
64 bytes from muc11s01-in-f14.1e100.net (172.217.22.206): icmp_seq=1 ttl=53 time=40.2 ms
64 bytes from muc11s01-in-f14.1e100.net (172.217.22.206): icmp_seq=2 ttl=53 time=41.8 ms
64 bytes from muc11s01-in-f14.1e100.net (172.217.22.206): icmp_seq=3 ttl=53 time=47.4 ms
64 bytes from muc11s01-in-f14.1e100.net (172.217.22.206): icmp_seq=4 ttl=53 time=41.4 ms
^C
— google.com ping data —
4 packets transmitted, 4 gotten, 0% packet control, opportunity 7ms
rtt min/avg/max/mdev = 40.163/42.700/47.408/2.790 ms
The ping command resolves the domain into an IP address and begins giving ICMP bundles towards the location IP. A line that includes the following fields if the destination IP is reachable it will respond back and the ping command prints
The sheer number of facts bytes. The default was 56, which translates into 64 ICMP data bytes – 64 bytes
The internet protocol address associated with the destination – from muc11s01-in-f14.1e100.net (172.217.22.206)
The ICMP sequence wide variety for every single package. icmp_seq=1
The full time to live on. – ttl=53 – How does TTL jobs?
The ping energy, assessed in milliseconds which can be the trip that is round for the packet to attain the variety, and for the response to go back to the transmitter. – time=41.4 ms
By standard, the period between sending a new packet is actually one second.
The ping command will continue to submit ICMP bundles for the location IP address until it receives an interrupt. To prevent the order, just smack the Ctrl+C trick mixing.
Once the command stops, it exhibits a statistic like the portion of package control. The package loss suggests the information was actually dropped someplace in the network, indicating an presssing issue inside the system. When there is a packet reduction, the traceroute can be used by you command to determine where in actuality the packet loss happen.
If ping does not come back a reply, this means that the system interaction is not developed. At these times, it doesn’t always signify the resort internet protocol address is certainly not energetic. A firewall may be had by some hosts this is certainly preventing the ICMP traffic or set never to respond to ping demands.
On triumph, the ping command exits with code 0. Otherwise it will leave with laws 1 or 2. this is often helpful while using the ping energy in a layer script.
When you look at the following areas, we’ll go on top of the most often utilized command that is ping.
