What is the best way to limit concurrent connections per IP to, say, 20?
I'm having some problems with "connection storms" caused by bots
harvesting websites.
mod_limitipconn.c ?
http://dominia.org/djao/limitipconn2.html
Never tried it, but looks like it should work.
Or, just use iptables?
iptables -A INPUT -p tcp --syn --dport 80 -m connlimit --connlimit-above
20 -j REJECT
Anyone had experiences with that?
What number of connections should I allow not to cut off legitimate
users? 20? 30?
