I recently learned this and I wanted to know how to ping an ip address like forever without stopping because usually when you send the ping command it only pings like for four times, then it stops, but i am monitoring a server and to ping continuously all you have to do is use the -t option
For example, if you want to ping this ip: 192.168.1.155 you would send this command in the Windows DOS terminal, Linux or OSX:
DOS COMMAND:
ping 192.168.1.155 -t
top stop it, just hit control+c
that's it
