A easy question.
this is the simple question, please help me!

the question is: how to send exactly 50 ICMP Echo request packets with 500 bytes of payload to 202.139.129.221?

I tried to use ping -F 500 202.139.129.221, but it didn't work.

Thanks!

Try using

ping -s 500 202.139.129.221 500 50

Most OS's have their own implementation of "ping" with slightly varying syntax. What is the output of uname -a?

Cheers

shell:
[kuqiu:~] ping -s 500 202.139.129.221 500 50
ping: bad data size: 202.139.129.221

this is the result......still can not find out the way.....T_T

My apologies:
try this one -

ping -s 202.139.129.221 500 50

Hmm. You still didn't post the output of "uname -a" - i.e. which OS you are using.

Anyway, examples of correct ping usage are:

Solaris/HP-UX:
ping 202.139.129.221 500 50 # with solaris use -s

Linux:
ping -c 50 -s 500 202.139.129.221

Windows (i.e. Cygwin)
ping -n 50 -l 500 202.139.129.221

One of these should work for you

----202.139.129.221 PING Statistics----
50 packets transmitted, 50 packets received, 0% packet loss
round-trip (ms) min/avg/max = 23/56/168




this is 0% packet loss, but if I want to find out where there could be packet loss, how can I do?
