Ping me maybe
ping is a command that tests a source computer's connection with a destination machine.
Open your terminal and give one of the following a try.
ping localhost
ping 127.0.0.1
ping example.com
It's all about the flags
Like any good Unix command ping has a host of flags. Let's explore some.
-A audible
Sound an audible beep when a packet is received before the packet what was sent before it.
ping -A localhost
-a audible
Sound an audible beep when a packet is received
ping -a localhost
-c count
Stop after sending and receiving count packets.
ping -c localhost
-i wait
Wait wait seconds between sending packets. You can only increase/decrease in
1/10 second increments.
ping -i localhost
-f flood
Output packets as fast as they come back or 100 times per second whichever is
faster. WARNING: This is basically a Denial of Service (DoS) attack and it can be illegal
to do against a computer that you don't own. I highly suggest only doing this on
your own machine or a machine that you own.
Only a SuperUser can use this command.
ping -f localhost
It's worth noting that when I just ping my localhost I have 0% packet loss.
However when I ping -f my localhost I have usually around a 20% packet loss.
-l preload
Send preload numer of packets as fast as possible before falling into normal
mode of behavior.
Only a SuperUser can use this command.
ping -l 100 localhost
-n
Numeric output only.
ping -n localhost
-o
Exit successfully after receiving only 1 packet.
ping -o localhost
-q
Quiet output. Only show summary at startup time and when finished.
ping -q localhost
-Q
Somewhat quiet output.
ping -Q localhost
-R
Record route. Many hosts ignore or discore the record route option.
ping -R localhost
