There are different websites, which will give the status of your server from worlds different locations. User can use the ping command to check the reachability of your server from different locations. Checking reachability of your server from different locations : If you specify the less time then the timeout error will come. This actually specifies the total number of seconds the Ping command to send the packet to remote host. User can set the specific time to send the packets in the network. The packet size is 100 and its header size is 28. The size is showing 128 which is nothing but the Packet header size + packet size. Ping Bytes Sent = Ping Packet Size + Ping Header Packet Size (28 bytes) Ping command is used to change the packet size using – s option of command.
The user will get the beep sound after the remote computer is reachable. The disadvantage of this option is this option will not work with console. You can continue working with your changes, and when the remote machine become reachable you’ll hear the beep automatically. The –a option of ping command is used for audible ping.This option is useful for system admin for troubleshooting. The ping will exit after response or error. The above ping command will send 5 packets over the network and waits for response from destination. Using this option the ping command will exit automatically rather than pressing CTRL + C to exit. c option of ping command will send N packets over the network and then exit. The –V option is used to show the current version of ping program. The –V option of ping is used to show the version and exit. The above ping command will wait 1 milliseconds before sending next packet. The above ping command will wait 5 seconds before sending next packet. Only super user can specify interval less than 0.2 seconds. Minimum = 0ms, Maximum = 0ms, Average = 0msģ.Increase or decrease the time interval between packets :īy default the Ping Command will wait till 1 second to send next packet.User can increase or decrease the packet interval by using –i option of ping. Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Īpproximate round trip times in milli-seconds: User can ping the ip address of local computer to check it is added to network correctly.User can check the connectivity of default gateway as well as remote host. Reply from 127.1.0.1: bytes=1450 time<10ms TTL=32Ģ.Ping IP address of local computer / Default gateway / remote host : Ping the loopback address to check TCP-IP connection is working fine. If you are thinking that the ping is very simple command used to check the connectivity of the network, there are other uses of ping command.įirst and most important use of ping command is to diagnose the network connectivity. The ping command is used to isolate the network hardware problems. If user will get proper reply then the network is working properly. It usually sends the request to the computer in the network or device in the network. The Ping command is used to check the connectivity with your source computer with the set of devices in the network. The Ping Command in UNIX is used to test ability of source computer to reach specified destination. When you work in distributed environment, you need to communicate with remote users and need to access remote machines. I have already explained about the file creation in UNIX using multiple ways. In UNIX, there are lot of communication utilities and user needs to use set of UNIX commands.
