I am trying to ping one of my local host and checking CPU process to see how "Ping of death" attack behaves. I tried to ping my other PC which is in local network with 192.168.44.2 IP Address. I tried this,

ping -l 5000 192.168.44.2

and I got error like this,

ping: -l flag: Operation not permitted

I am on MacOSX Lion. How can I remove this flag so machine can let me ping with preload?

Thanks for any direction!

I'm a bit out of touch with Lion but do you not need to use sudo for some of the more advanced ping options?

I've been using Ubuntu of late and I know I must use sudo to use the -i option to set a delay between pings of less than 0.2 seconds.

Exactly I needed sudo su, and than get more permission for power :) thanks – Brogrammer Nov 22 '11 at 9:40
I can confirm this. I just tried it on my Lion box and it worked with sudo and gave the same "Permission denied" error without. – Ladadadada Nov 22 '11 at 9:40
sudo su, can you just sudo? Or where you being general there? :) – javano Nov 22 '11 at 9:41
