    Server box (F9) has:

    # Controls the use of TCP syncookies
    net.ipv4.tcp_syncookies = 1

    timestamp of /etc/sysctl.conf: 2008-05-15, installation default i think.

    Other (F8) box has:

    # Controls the use of TCP syncookies
    net.ipv4.tcp_syncookies = 0

    timestamp of /etc/sysctl.conf: 2007-01-28, touched 1.5 years ago.

    Have not checked the install defaults - if i touched them it was a long
    time ago.

    Ingo
