you could also do the following:

Alvin,
That's it. I saw instructions on the internet to update /etc/sysctl.conf, but they did it wrong. Your command line works!
Thank you.
I will be updating my website to show easy install methods for Ubuntu and Fedora.
Greetings I have ping disabled directly on my router so none of the machines behind it can be accessed from outside. Why wouldn't you do it there? A possible answer is that you are using the laptop truly mobile but that would be the only need for such a mod imo. For those that 'know' is there any other scenario where you might want to disable ping access on a machine basis? Regards Dee
