Ping Command in Linux
The ping order is one of the most put utilities for troubleshooting, examination, and identifying community connection problem.
Ping functions by giving more than one ICMP (websites regulation information Protocol) Echo consult solutions to a specific location internet protocol address from the circle and delays for an answer. When the destination obtains the bundle, it shall reply back once again with an ICMP echo response.
With the ping command, you are able to see whether a destination that are remote is effective or sedentary. There are also the round-trip wait in communicating with the destination and check whether there is certainly a packet loss.
The ping electricity is actually a right part regarding the iputils (or iputils-ping) package, and that is pre-installed on almost all Linux distributions. ping can be available on screens, macOS, and FreeBSD.
The way you use the Ping Command
The syntax for any ping command is just as follows:
ping [OPTIONS] DESTINATION
To finest illustrate exactly the ping demand works let’s ping google.com:
Ping.com that is google
The productivity shall check something such as this:
PING.com that is google (188.8.131.52) 56(84) bytes of information.
64 bytes from muc11s01-in-f14.1e100.net (184.108.40.206): icmp_seq=1 ttl=53 time=40.2 ms
64 bytes from muc11s01-in-f14.1e100.net (220.127.116.11): icmp_seq=2 ttl=53 time=41.8 ms
64 bytes from muc11s01-in-f14.1e100.net (18.104.22.168): icmp_seq=3 ttl=53 time=47.4 ms
64 bytes from muc11s01-in-f14.1e100.net (22.214.171.124): icmp_seq=4 ttl=53 time=41.4 ms
4 boxes transmitted, 4 received, 0% packet control, times 7ms
rtt min/avg/max/mdev = 40.163/42.700/47.408/2.790 ms
The ping command resolves the domain name into an ip and initiate giving ICMP plans into the location IP. In the event the resort IP try reachable it’s going to reply back and the ping order images a range that includes listed here sphere:
How many data bytes. The standard is actually 56, which means 64 ICMP data bytes – 64 bytes
The ip in the resort – from muc11s01-in-f14.1e100.net (126.96.36.199)
The ICMP series wide variety for each package. icmp_seq=1
The full time to call home. – ttl=53 – so how exactly does TTL efforts?
The ping opportunity, determined in milliseconds that will be the round trip energy when it comes down to packet to achieve the host, and for the a reaction to return to the transmitter. – time=41.4 ms
By default, the interval between delivering a packet that is new one next.
The ping command shall continue to deliver ICMP products with the Destination ip until it receives an interrupt. To cease the order, only hit the Ctrl+C trick blend.
The moment the command puts a stop to, it shows a statistic including the portion of package control. The packet reduction suggests the data had been fallen someplace in the circle, suggesting an issue around the community. If there is a packet control, the traceroute can be used by you demand to determine where packet control starts.
If ping will not go back an answer, this means that the system communications is certainly not founded. When this occurs, it doesn’t always mean that the resort internet protocol address is not productive. Some offers possess a firewall that will be stopping the ICMP traffic or ready never to respond to ping requests.
On achievements, the ping command exits with code 0. Otherwise it will leave with rule 1 or 2. this is beneficial with all the ping electricity in a cover program.
When you look at the next sections, we’ll get on top of the mostly utilized command that is ping.
