6.8. [ping]

ping is the name of a computer network tool used on TCP/IP networks (such as the

Internet). It provides a basic test of whether a particular host is operating properly and

is reachable on the network from the testing host. It works by sending ICMP packets to

the target host and listening for replies

For example: if 192.168.1.2 is not existing while 192.168.1.1 exists. Users will have

the following results:

usr/config$ ping 192.168.1.2

PING 192.168.1.2: 56 data bytes

no answer from 192.168.1.2

usr/config$ ping 192.168.1.1

PING 192.168.1.1: 56 data bytes

64 bytes from 192.168.1.1: icmp_seq=0. time=5. ms

64 bytes from 192.168.1.1: icmp_seq=1. time=0. ms

64 bytes from 192.168.1.1: icmp_seq=2. time=0. ms

64 bytes from 192.168.1.1: icmp_seq=3. time=0. ms

----192.168.123.100 PING Statistics----
