[lug] making ping not respond

[Brad Doctor]

This will do it:

   if [ -e /proc/sys/net/ipv4/icmp_echo_ignore_all ]; then
           echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
   fi


  # Ignore any broadcast icmp echo requests
  # 
   if [ -e /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts ]; then
           echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
   fi

  # Don't accept ICMP redirects
  #
   if [ -e /proc/sys/net/ipv4/conf/all/accept_redirects ]; then
           echo 0 > /proc/sys/net/ipv4/conf/all/accept_redirects
   fi

However, it will disable ICMP for all interfaces...
