2. If are seeing a lots of “TCP: drop open request from A.B.C.D” messages and you don’t expect a real load the server, you’ll need to enable syncookies. Edit your /etc/sysctl.conf and append the following lines:
# enable syncookies
net.ipv4.tcp_syncookies = 1

from terminal, type sysctl-p to reload the kernel configuration.
