archlinux.org claims "If you never customized /etc/sysctl.conf, you have nothing to do", while archlinux.de's claim is that only those settings
"# Protection from the SYN flood attack. net.ipv4.tcp_syncookies = 1 # Disable packet forwarding. net.ipv4.ip_forward = 0 net.ipv6.conf.all.forwarding = 0"
were used by a /etc/sysctl.conf that never was customized.
These were the only *uncommented* settings in our old sysctl.conf but, since they are kernel defaults now, there is no need to put them in any sysctl conf file anymore. The meaning was probably lost in translation, which is not surprising as in German it is hard to make precise statements with great accuracy. When in doubt, always trust the one true original archlinux.org. :) -- Gaetan
