Hello,
Was playing with te iptables and suddenly had the problem.

I'v tried to add the following rule to limit number of connections to 80 port:

Code:
-A INPUT -p tcp --syn --dport 80 -m connlimit --connlimit-above 5 -j REJECT


And get the following error in /var/log/messages:

Code:
kernel: ip_tables: connlimit match: invalid size 32 != 16


Do zcat /proc/config.gz | grep -i connlimit and get CONFIG_NETFILTER_XT_MATCH_CONNLIMIT=y - so connlimit is supported by the kernel?

Is it possible to load connlimit iptables module?

OS: Debian 4.0

Thanks.

Put it into bugs/reports section.

This thread can be closed I guess.
