Topic: Any way to stop my server from replying to a ping?

[Drifting]

Sorry if this is an FAQ, I have searched though the site as best I could.

What I really want to do is stop my server replying to a ping? is it possible? I have noticed in my snort logs that our ISP seems to be suffering from windows machines with worms? or something? The log always starts with a ping, then proceeds to do a port scan. However I have another server on the same ADSL line (With another IP) which has MS ISA server, which I have managed to stop responding to ping requests, and that very rarely gets port scanned.

I have SME 5.6 with latest patches.

Have I lost the plot over this? as I am a newbie to SME and Linux.

This is a very old subject. Try searching first.

I you are trying to stop Cyberkit ICMP Pings, check out this thread: http://forums.contribs.org/index.php?topic=18665.msg73540#msg73540

I just did this to my own firewall.  There is probably an easier/better way of doing this, but it works.

copy: /etc/e-smith/templates/etc/rc.d/init.d/masq/90adjustICMPIn
to: /etc/e-smith/templates-custom/etc/rc.d/init.d/masq/90adjustICMPIn
edit the section: my @OKicmpTypes
Remove the line that says: echo-request
run: /sbin/e-smith/expand-template /etc/rc.d/init.d/masq
run: service masq restart

Try a firewall tester like Shields-up at http://www.grc.com to see if you can be pinged.

Hope that helps
