Greetings folks, I've been researching the various iptables modules that are included with the stock CentOS4 distro; particularly the connlimit module. Is connlimit included by default? I thought it is since performing # iptables -m connlimit --help returns information on connlimit usage along with the general iptables help info: <SNIP> connlimit v1.2.11 options: [!] --connlimit-above n match if the number of existing tc...

...CC| |netfilter at linuxace.com Resolution| |WORKSFORME --- Comment #2 from Phil Oester <netfilter at linuxace.com> 2013-06-06 18:09:21 CEST --- This works fine for me on recent kernels. Perhaps you misunderstand that connlimit means you need SIMULTANEOUS connections opened? It does not track CLOSED (historical) connections. Example on 3.10 kernel: # iptables -A INPUT -p tcp --syn --dport 25 -m connlimit --connlimit-above 2 -j REJECT Connection #1: # telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Es...

...user (client ip). So, different IP can have its own rate limit. This scheme ir working fine for a long time. But how can I limit number of connections (sessions) from one host? I see from ip_conntrack that some of users have more than 1000 active connections (mostly P2P udp). As I know there is connlimit patch for iptables, but it capable to limit only tcp sessions. And there is ESFQ qdisc, allowing to divide bandwidth more fairly, but inside one class. In my case every user have its own class and I''m not able to control how many connections simultaneously they do implementy ESFQ! Also I...
