Disabling ping requests

[Azerate]

Basically i want my Android phone to stop responding to ping requests.

I tried searching but i found no solution to this matter.

Has anyone done this? What's the easiest solution to permanently prevent the phone from responding to ping requests?

My phone is rooted and running 2.1 if that helps.

You can use iptables:
iptables -A INPUT -p icmp -j REJECT

Thanks for the reply!

This works great until i restart my phone.

What would be the best way to store this setting permanently?

I tried searching for an iptables config file but i couldn't find any.

iptables has no config file, you need run a script with all rules.
In the market you can find Autostart (root) to run a script at boot.

I downloaded Autostart and then ran the following commands:

su
mkdir /data/opt
echo "iptables -A INPUT -p icmp -j REJECT" > /data/opt/autostart.sh

Then i rebooted, pressed "Allow Always" for Autostart and rebooted once more.

Still i can ping my phone. Did i do anything wrong? Any more suggestions?

Check the rules with 'iptables -L -nv'
If nothing, try with the full path to iptables on the script (/system/xbin/iptables) and 'chmod 755 /data/opt/autostart.sh'
