    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

    Edit the config from WHM -
    Find the module in the bottom left ConfigServer FireWall
    Firewall Configuration.

    Search for PING in your list of options, you'll come across

    (1 means yay, 0 means nay)
    # Allow incoming PING
    ICMP_IN = 1

    when i change ICMP_IN_RATE = 0 from 1/s, the ping works.

    but is it safe?

    We have been running that on all our servers for awhile now. No problems.
