iptables firewall to protect against automated entries
- by Kenyana
I am getting unusually large calls on my app. I have implemented CSRF Check over ajax and its working but am still getting so many calls. My guess is that someone has a script that is 'logged' in and making all these calls. Could someone please share a good iptables script for blocking ip's that run 10 calls to /controler/action in a second.
I am using `/sbin/iptables -A INPUT -p tcp --syn --dport $port -m connlimit --connlimit-above N -j REJECT --reject-with tcp-reset
save the changes see iptables-save man page, the following is redhat and friends specific command
service iptables save`
That is from cyberciti
