------- Additional Comments From lionel.ulmer@free.fr 2004-20-02 10:34 ------- If you do "ls -l `which ping`" on your Linux box, you will get :
-rwsr-xr-x 1 root root 15312 Nov 3 1999 /bin/ping
And you will see the SUID bit set.
In other words, in the Unix world, only root can send ICMP packets. So to be able to ping without using the 'ping' program, you need to be root.
