? What can be done to stoop this message?
You could do this:
# echo 0 > /proc/sys/net/ipv4/tcp_syncookies
Or, if you want it permanent (after reboot), set: net.ipv4.tcp_syncookies = 0 in /etc/sysctl.conf

I am also getting TCP SYN flooding msg in dmesg of Haproxy host m/c:
[ 2965.742025] possible SYN flooding on port 80. Sending cookies.
Command cat /proc/sys/net/ipv4/tcp_syncookies is set to 1.
What can be done to stoop this message?
