Hi, 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. I never customized the /etc/sysctl.conf on my machine, but it contains other enabled entries too. $ grep -v "#" /etc/sysctl.conf.pacsave net.ipv4.tcp_syncookies = 1 net.ipv4.ip_forward = 0 net.ipv6.conf.all.forwarding = 0 kernel.sysrq = 0 vm.swappiness = 10 fs.inotify.max_user_watches = 524288 This is confusing.
