This post is for the following situation:
You’ve installed “Suse 11.0” on your computer. Although all of your computer’s ports are stealth mode, your computer still replies to random ping request.
Solution 1 of 2
Google the following items
#echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all
#echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
Do they work? Probably, I’ve never tried it.
Using solution, do I know how to backup the file to be modified? Do I know how to tell you to import and then export this file should you make a mistake with its implementation or in the event that the Googled instructions prove to be invalid? Do I know how to tell you o backup and save your original configuration should something go wrong? The answer to these questions for solution one only, is no. Solution 2 goes without saying and so the answer is yes. 
Solution 2:
Have I tried it?
Yes, and it worked like a charm, and here it is. Oh by the way, it easier to execute than the steps or the number of steps indicate.
Please message me if you find an error and if it helped you, thanks
Solution 2 of 2
-
From the desktop, lower left-hand corner click start, the lizard looking icon.
-
Click the “applications” tab.
-
Scroll to “system” and then left click it.
-
The menu changes, now left click “Yast admin settings”
-
After a an extremely short delay, the “Run
as Root” dialog appears. -
Enter the “root password.”
-
After a short delay, the “Yast Control
center” Dialog box will appear. -
Within the left-hand column of the “Yast
Control center” Dialog box, select “system” -
From near the top of the “Yast Control
center” Dialog box, select “/etc/sysconfig
editor.”
The “yast2 dialog box will appear although
it will take awhile, 2 seconds on my
system. -
In the lefthand column click “Network.”
-
From the collapsible drop-down menu (menu
tree for some) click “Firewall.” -
From the collapsible drop-down menu (menu
tree for some) click “Suse "Firewall2.” -
From the collapsible
drop-down menu (menu tree for some)
scroll to “FW_ALLOW_PING_FW”
Note: You’ll be scrolling for quite some time as the “FW_ALLOW_PING_FW” is beyond the halfway point of the collapsible
drop-down menu (menu tree for some)
-
In the upper center part of the screen,
verify that the words “FW_ALLOW_PING_FW”
are there. Then, slightly below and to the
far right click the down arrow and
select “No.” -
In the lower right-hand corner, click the
“finish button.” Wait for the ensuing
computer activity to finish. -
Exit these dialog boxes and then restart
the system.
Congratulations, your system will no longer reply to random ping request!
