which system command should I use to make some ICMP activity? I tried to use system("ping www.google.com");, but it looks like program does not read further code after that.

Or how to make it read after system("ping www.google.com");?

For example:

#include <stdio.h>
#include <stdlib.h>
int main() {

    system("ping www.google.com");
    printf("\ncheck");
}

outputs PING www.google.com (173.194.78.105) 56(84) bytes of data (no check) and I need to stop the program myself afterwards

Maybe "ping -c 1 ..."? – drull Nov 29 '13 at 15:20
it says `ping: bad number of packets to transmit` if I do `ping -c` – maximilliano Nov 29 '13 at 15:29

Which OS? On Linux "ping -c 1 www.google.com" works. On windows it will be "ping -n 1 www.google.com" – drull Nov 29 '13 at 15:31
1

And looks like you forgot "1" after "-c" – drull Nov 29 '13 at 15:32
well it still does not printf `check`, but yes, it works with 1 – maximilliano Nov 29 '13 at 15:52
weird. for me it ok. http://pastebin.com/EsME63QJ . as you can see it prints "check" in one line with "root@localhost", maybe you just didnt notice it? – drull Nov 29 '13 at 16:04
I am using QEMU. It seems like the program is runnig, cause I need to exit from program myself, I do not have bash otherwise – maximilliano Nov 29 '13 at 16:06
Add a `flush(stdout);` after the `printf()`. – alk Nov 29 '13 at 17:32
used fflush, nothing changed, just flush does not work – maximilliano Nov 29 '13 at 17:36
