CSF causing server Ping timeout




Posted by hbhb, 07-28-2008, 12:18 AM
I just installed a fresh new server with CSF Soon I find out that my ping keeps dropping. The server was smoothly running, SSH is smooth, Website are loading fine, except I cannot ping my server. I disable SELINUX completely and it still doesn't help. When I disable CSF, my server ping are responding back! So I remove CSF installation and reinstall CSF, the same problem appear How can I solve this issue? My kernel is 2.6.18-92.1.6.el5PAE running on latest version of cPanel on CentOS 5.1

Did you install this as part of a package, or did you install it from the source package?

Check the ping rate in CSF configuration Increase the rate to 2-3 per second.

Allow incoming PING ICMP_IN=1 # Set the per IP address incoming ICMP packet rate # To disable rate limiting set to "0" ICMP_IN_RATE=1/s should i change it to 3/s ?i installed it by following http://www.configserver.com/free/csf/install.txt

when i change ICMP_IN_RATE = 0 from 1/s, the ping works. but is it safe?

Hi I have set ICMP_IN_RATE to 30/s And now result is showing okay except 1/2 places. see the result here http://easycaptures.com/fs/uploaded/371/5512036852.png Cheers!

it`s safe but not a good way, i think it`s better if you Set this per IP address ICMP_IN_RATE =
