Hello, my server is under SYN Floods Attacks.
There is many R ( Request Reading ) Proccess in apache Status. i searched the web and found a solution :

Add this commamds in on /etc/sysctl.conf

net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_syn_backlog = 2048
net.ipv4.tcp_synack_retries = 3

is these commands safe for cpanel and cloudlinux 7 enviroment ? can they cause any problem ?

Best Regards

i dont want cpanel / cloudlinux enviroment like updates , ... get problems with this change.
