 * 1) Disable response to broadcasts.
 * 2) You don't want yourself becoming a Smurf amplifier.
 * 1) enable route verification on all interfaces
 * 1) enable ipV6 forwarding
 * 2) net.ipv6.conf.all.forwarding = 1
 * 3) increase the number of possible inotify(7) watches
 * 1) avoid deleting secondary IPs on deleting the primary IP
 * 1) # Inicio das Configuracoes
 * 1) disable SYN cookies
 * 2) Note: make sure this syncookies=1 item is commented out (it will already exist in this file).
 * 1) increase the TCP backlog to increase simultaneous new connection creation abilities
 * 1) increase and recycle TCP connection blocks for reuse in an optimal manner
 * 1) disable Selective Acknowledgements for 1GBps networking
 * 1) increase kernel memory by doubling the default (check your system first!)
 * 2) the value of this item will be related to the memory in your system
 * 1) manage the TCP network buffer sizings
 * 1) # Fim das Configuracoes
